Forum member Mike T. (aka “Watercam”), has cleverly adapted a tubegun cheek piece to conventional fiberglass and wood stocks. The cheek piece hardware comes from Competition Machine and is the same as used on Gary Eliseo’s tubegun stocks. Here is Watercam’s Project Report:
Installing Tubegun Cheek Piece on Conventional Gun Stock
All of my match rifles are equipped with thumb-wheel adjustable cheek pieces for the best of reasons — adjustments can be made while in position, on target. I’ve learned that variations in position, terrain, and vertical angle all demand adjustability to achieve optimal cheek weld.
I wanted a cheek piece for my hunting and tactical type stocks that gave the same adjustability without having to cut a chunk off of my butt stocks. It needed to be affordable and easy to install. I also wanted a unit that would not push my head laterally away from the centerline of the scope or iron sights. Turns out I already had what I needed on my Gary Eliseo B-1 tubegun. I ran the idea past Gary, who said: “If you’ll be the guinea pig I’ll send the hardware”.
Using Gary’s hardware, I mounted Eliseo alloy thumb-wheel adjustable cheek pieces on a Bell & Carlson Medalist hunting stock and a Boyd’s laminate tactical stock. Read Forum Discussion.
Building Version One on Bell & Calson Stock
I had a Bell & Carlson Medalist stock for a Mauser 98 chambered in 9.3×62. This test rifle was enough of a thumper to reveal if the metal cheek piece could handle strong recoil.
I started by drilling three 1/2″ holes into the top of the comb to match the two pillars and one threaded shaft on the cheek piece. I used aluminum tubing to make guides for each and epoxied them in place. Inletting the oval hole for the thumb wheel was reasonably straight forward and the fiber reinforced foam in the buttstock offered enough support. A large flat washer epoxied underneath where the thumbwheel lay gave a smooth bearing surface. Total adjustment (with 2.25″ pillars and shafts) is just about an inch. I chose to trim the bottom of the skirt of Gary’s cheek plate so as to allow better position behind the scope for me and allow maximum adjustment even with the cheek piece of the stock. Set screws could be used instead of the thumb-wheel or in conjunction with it. In the end it was exactly what I envisioned and works great! The only thing left to do is paint the metal to match the stock.
Version Two — Installed on Boyds Laminated Tactical Stock
Watercam’s second metal cheek piece installation was on a laminated tactical stock. This Boyds stock did have a movable comb, but the original adjustable cheek section was too awkward to adjust from position. So I adapted the Eliseo cheek piece to to the Boyds stock, as you can see:
Cheek piece installation for both stocks was straight-forward, and the new cheek pieces work every bit as well the systems on my match rifles. Aluminum tubes epoxied in place guide the rods and threaded shank. A matching-diameter flat washer epoxied under the wheel provides smooth bearing surface. The glass-filled filler of the butt stock is plenty strong enough to support the unit. A set screw and knob can be added to lock in changes if so desired.
Many of you may not have seen how Jerry Stiller’s innovative Drop-Port works with a 6BR, PPC, or Dasher case. Stiller Precision has created one slick system. Just retract the bolt and your case exits, nose-first, through a small port, coming to rest right under the gun. It works by gravity alone so you don’t need a conventional ejector, with the case alignment issues an ejector can create. (An ejector pushes on one side of the rim — this can push the case out of “perfect” alignment.) While Drop-port technology could, potentially, work with nearly any size cartridge, at this time, Drop-ports are only offered for PPC, 6BR, and Dasher-sized cases. Your Editor has a Drop-Port Viper action used with the 6mm BRDX cartridge, which is similar to a Dasher but with a slightly longer neck. It works flawlessly. Our Belgian friend David Bergen was kind enough to video his Viper Drop-Port in action:
Currently, the Drop-port system is available with the Viper action (both aluminum and stainless), and the round-profile Diamondback actions (but expect to wait a LONG time if you want the flat-bottomed Viper action). Because of the nature of Drop-port geometry, this system is optimized for short-length benchrest cartridges such as the 220 Russian, 22 and 6mm PPC, 6mmBR, and the 6mmBR Improved (Dasher, BRX, BRDX). If you plan to use a Drop-port with a Dasher or other improved case, you should tell Stiller Precision when you order. Also, if your gunsmith has not built a Drop-port rifle before, he should first consult with Stiller Precision, (972) 429-5000, to ensure the exit port is placed and inletted correctly in the stock. Getting the geometry exactly right is critical with this system.
Muzzle brakes are controversial. Some people swear by them, while others swear at them. Still, there’s no question that a good brake can reduce felt recoil up to 45%. And likewise, the best brakes, when installed properly, seem to have no negative effect on accuracy.
Roy Bertalotto has done considerable experimentation with muzzle brakes, testing dozens of brake designs on his own rifles over the past few years. Roy’s article, Adventures with Muzzle Brakes, discusses various aspects of muzzle brake design and performance. Roy doesn’t claim that his testing is definitive, but his article is definitely worth a read. Here are some of Roy’s interesting findings:
Exit Hole Diameter
“Best accuracy and effectiveness of the brake was obtained with a hole .020″ over bullet diameter. If the exit hole is too small, such as +.005″ over bullet diameter, accuracy suffers. If the depth of the exit hole is too shallow, the metal around the hole will erode very quickly.”
Hole Placement
“The most effective braking was with a brake 1″ in diameter with a 3/4″ exit hole on each side, just in front of the muzzle. The bullet passes through a cone of 35 degrees before it exits the brake. (Like the tank example), Incredible reduction of recoil. But loud and ugly. Very easy to make since you don’t need a spin fixture or a dividing head.”
Bottom Gas Venting Helps Accuracy
“In my tests, not having holes all around the brake effects accuracy a bit. I believe it does something to the bullet by the air pushed ahead of the bullet creating unequal turbulence in the bullet path. I’ve tried a few brakes where I drilled only holes on the top, test fired, and then completed holes on the bottom and in every case, accuracy improved.” Below are spiral-ported brakes crafted by Clay Spencer.
Brakes Work Best with High-Pressure Cartridges
“The higher the pressure of the particular round, the more effective the brake. I have over 20 rifles with brakes. The 220 Swift is the king of reduction. Followed very closely by the 25-06, 6mm Remington, any Weatherby small bore. With a proper brake and a hot handload under a 40 gr bullet, the Swift will move 1/2″ to the rear and 0 muzzle rise! Big boomers with low pressure like 45-70s and shot guns benefit the least.” [Editor’s Note: Roy is judging effectiveness by the percentage of recoil reduction rather than absolute levels of recoil. Obviously if you start with a heavier-recoiling round, the absolute amount of recoil energy reduction is greater. Roy is really talking about efficiency–brakes are most efficient when used with high-pressure cartridges.]
Installation is Key to Accuracy
Roy’s findings are fascinating and suggest that further study of muzzle brakes is warranted. But we can all agree that precision installation of the brake is essential for accuracy. A poorly-installed, mis-aligned brake will degrade accuracy, that is well-known.
Harrell’s Precision has made thousands of muzzle brakes, in many styles and port arrangements. The Harrell brothers offer some good advice for gunsmiths installing brakes: “Muzzle brakes aren’t magic, they reduce recoil by redirecting exiting gas. What’s important is that they are straight and the threads are perpendicular with the base. The only way to get the base and threads perpendicular is to thread, not tap, them on a lathe.”

On July 22, 2016 the U.S. Department of State’s Directorate of Defense Trade Controls (DDTC) issued a 4-page “Guidance” concerning gunsmithing activities. This “Guidance” described the types of tasks and services which would obligate gunsmiths to register as “manufacturers” under the Arms Export Control Act (AECA) and International Traffic in Arms Regulations (ITAR). Any “manufacturers” of “defense articles” (which includes firearms and ammunition) must fill out burdensome paperwork every year and pay an exorbitant $2,250 annual registration fee. The “Guidance” stated that completing even one simple smithing task, such as threading a muzzle, will obligate a smith to register as an ITAR “manufacturer”. And this holds true even if the “manufacturer” does not export a single product, or only makes component parts, such as a wood gunstock. READ 7/22/2016 DDTC Guidance.
Clearly this “Guidance” threatens the traditional activities and livelihoods of normal, non-exporting gunsmiths around the country. The potential penalties for failure to register are draconian — huge fines and up to 20 years in prison.
Recognizing that the latest DDTC “Guidance” represents a severe threat to the firearms industry, the National Shooting Sports Foundation (NSSF) is leading an effort to get the DDTC to change its policies. The NSSF also urges concerned citizens to contact their elected representatives in Washington.
NSSF Statement Regarding DDTC’s Firearms “Guidance” on ITAR Registration
DDTC asserts that the guidance merely restates existing DDTC policy and interpretation of the AECA and ITAR manufacturer registration requirement.
Unfortunately, DDTC’s “guidance” has created considerable and understandable confusion and concern among gunsmiths and gun owners. The National Shooting Sports Foundation (NSSF) is reviewing the guidance and will send a letter of protest to DDTC expressing our strong opposition to the new “guidance,” the scope of which clearly exceeds their statutory authority. The term “manufacture” as used in the AECA and ITAR is its ordinary dictionary definition. Clearly, many of the activities DDTC claims require registration constitutes gun smithing and is not manufacturing under any reasonable dictionary definition of the term. DDTC’s position is similar to claiming an auto mechanic who fixes your car is a car manufacturer.
NSSF has been working diligently for many years to eliminate, or at least significantly lower, the excessive and burdensome registration fee especially for non-exporting manufacturers and non-essential component parts manufacturers. Simply put, forcing small manufacturer to pay $2,250 annually to register when they are not utilizing the DDTC export licensing system to export products is an unfair and onerous regulatory burden. This is even more outrageous when one considers that DDTC is sitting on at least $140 million dollars of previously paid registration fees collected over many years from exporters from many industries including ours.
Additionally, we have been working with allies in Congress to pressure the Obama administration to complete the Export Control Reform (ECR) initiative, which would (with limited exceptions) do away with the AECA and ITAR manufacturer registration requirement and onerous fee for commercial and sporting firearms.
To date, the Obama Administration has refused to publish and implement the regulatory changes necessary to transfer [the] export licensing of commercial and sporting firearms and ammunition products to the Department of Commerce from the Department of State. Read more on Export Control Reform. Yet, the proposed rules have been drafted and ready for publication since December 2012. Inaction persists despite congressional testimony and letters to members of the U.S. House and the Senate that [the Administration] would publish the rules.
Why has the Obama administration refused to move ECR forward for our industry? It is really very simple. The Obama Administration is singling out our industry for different treatment under the ECR because of its gun control politics. It is time to force Congress to step in and stop the Obama Administration’s gun control agenda from stopping this needed reform.
Here is the key language in the DDTC’s “ITAR Registration Requirements – Consolidated Guidance” Ruling of 7/22/2016:
2. Registration Required – Manufacturing: In response to questions from persons engaged in the business of gunsmithing, DDTC has found in specific cases that ITAR registration is required because the following activities meet the ordinary, contemporary, common meaning of “manufacturing” and, therefore, constitute “manufacturing” for ITAR purposes:
a) Use of any special tooling or equipment upgrading in order to improve the capability of assembled or repaired firearms;
b) Modifications to a firearm that change round capacity;
c) The production of firearm parts (including, but not limited to, barrels, stocks, cylinders, breech mechanisms, triggers, silencers, or suppressors);
d) The systemized production of ammunition, including the automated loading or reloading of ammunition;
e) The machining or cutting of firearms, e.g., threading of muzzles or muzzle brake installation requiring machining, that results in an enhanced capability;
f) Rechambering firearms through machining, cutting, or drilling;
g) Chambering, cutting, or threading barrel blanks; and
h) Blueprinting firearms by machining the barrel.
How Can Gun Owners and Gunsmiths Help?
Call your U.S. Representative at 202-225-3121 and U.S. Senators at 202-224-3121 urge him or her to support Rep. Collin Peterson’s (D-Minn.) Resolution, (H. Res. 829) that demands the Obama administration complete the ECR and publish the proposed rules to transfer the licensing of commercial and sporting firearms and ammunition products to the Department of Commerce (which does not require registration or payment of a fee).
Tell your U.S. Representative and Senators to force DDTC to stop imposing excessive and onerous registration fees on small businesses that do not export products. Tell them to support language in the Fiscal Year 2017 State and Foreign Operations Appropriations bill that will reduce the registration fee to a nominal amount for all non-exporting manufacturers and component part manufacturers.
Tell your U.S. Representative and Senators to stop the Department of State and DDTC from exceeding their statutory authority. The DDTC should have no power to control non-export activities. Threading a barrel or fitting a stock should not oblige a gunsmith to register with the Department of State and pay a fee of $2,250 per year.
For anyone interested in accurate rifles, this is absolutely a “must-watch” video. Watch blanks being cryogenically treated, then drilled and lathe-turned. Next comes the big stuff — the massive rifling machines that single-point-cut the rifling in a precise, time-consuming process. Following that you can see barrels being contoured, polished, and inspected (with air gauge and bore-scope). There is even a sequence showing chambers being cut.

Chuck’s Pair of Pennsylvania Dashers
There’s been a lot of interest in the 6mm Dasher cartridge lately, so we thought we’d showcase a matched pair of Dasher rifles belonging to a Forum member. The 6mm Dasher began as a wildcat improved version of the 6mmBR Norma cartridge. The 6mm Dasher has been very successful in competition, and now factory Norma-made Dasher cartridge brass is available from Bullets.com.
Forum Member Chuck L. (aka “Ridgeway”) has created a handsome duo of 6mm Dashers for competitive benchrest and varmint matches in Pennsylvania. Both guns are built on Kelbly Panda RBLP actions, with Bartlein 8-twist barrels, and Shehane Laminated Tracker Stocks. However, the two rifles are not exact twins, as you can see. One, which we’ll call the Big Dasher, is built on a Shehane ST1000 Tracker stock. The other gun, the Small Dasher, sports Shehane’s “Baby Tracker” stock — a design used with great success by Richard Schatz. The Big Dasher, optimized for 1000-yard competition, also has a slightly longer freebore — 0.136″ vs. 0.104″ for the Small Dasher.
Specifications for the Dasher Duo:
Small Dasher (13.5-pounder): Chambered for 6mm Dasher with approximately .104 freebore and a .264 NK. (No way of knowing exactly since it freebore was done in a separate operation by Kelbly.) Components are: Shehane Baby Tracker stock, Kelbly Panda RPLB action, Bartlein 1:8″ LV barrel at 26 ¾”, Kelbly Rings, Weaver T36, Jewell trigger. The barrel was chambered by Kelblys and the stock was bedded, glued and balanced by a shooting buddy (Forum Member johara1). I clear-coated the stock with auto urethane. Total weight is 13 lbs., 4 ounces.
Big Dasher (1K Light Gun, 17-pounder): Chambered for 6mm Dasher with a .136 freebore and .264 neck (PTG Reamer). Components are: Shehane ST-1000 stock, Kelbly Panda RPLB action, Bartlein 1:8″ HV 5R barrel at 28″, Shehane +20-MOA rings, Nightforce NXS 12-42x56mm, Jewell trigger. The barrel work, pillar installation, and bedding was done by Dave Bruno. The stock was clear-coated by Chuck with auto urethane. Chuck also made the rear butt plate and balanced the rifle. Total weight: 16 lbs., 13 ounces.
Chuck tells us: “I don’t get out shooting competition as much as I want due to time and family, but when I do compete, I shoot a Groundhog match at Southfork Rifle Club in Beaverdale, PA. Info on Southfork Club events can be found at Southforkrifleclub.com. The Southfork match is basically a 100-, 300- and 500-yard match with one sighter the entire match and 5 shots at each yardage for score. The Small Dasher, with the shorter ‘Baby Tracker’ stock, was set up for the Southfork Rifle Club’s ‘Light Unlimited’ class which has a 13.5-lb max weight.” (Editor: ‘unlimited’ is a misnomer for a weight-limited category.)
Chuck adds: “The Big Dasher with the heavy ST-1000 stock is set up for 1000-yard benchrest matches in Light Gun class. I hope to shoot a couple 1K matches with it at Reade Range in southwest Pennsylvania. I am still in load development for this rifle since it was just finished in January. One ironic thing is, it shoots the same load I’m shooting out of the lighter gun rather well. The only difference between the two chambers is the freebore is roughly thirty thousandths longer on the 1K gun (Large Dasher). I will also shoot this at Southfork in the ‘Heavy Unlimited’ class.”
Dasher Case-Forming: Neck-Turn then Fire-form with Bullets Hard in Lands
To fireform, I turn my cases down to fit the chamber and stop where the false shoulder makes snug contact with the chamber. Fire-forming rounds are loaded up with a 29-grain charge of H4895 or Varget and a 108gr Berger bullet seated hard into the lands about 0.020″ past initial contact with the rifling. It takes about three firings to make a nice clean Dasher case with a sharp shoulder. I anneal about every 3-4 firings. I have many cases that have about 10+ firings on them and they are still shooting well. The primer pockets are a little looser, but still hold a primer.
Both Dashers Group in the Ones at 100 Yards
My main bullet for both rifles is the 107gr Sierra MK, loaded with Reloder 15 powder, Lapua cases and CCI 450 primers. My main load for the Small Dasher is 33.0 grains of Reloder 15. This load shoots in the ones at 100 yards. For the Big Dasher, I’m still working on a load, although the same 33.0 grain load shoots in the ones in the heavier gun as well. I’m still looking for more velocity and my ‘max’ node. So far, I’ve gone well above 33.0 grains of RL 15 without pressure signs, but that load produces vertical at 100 yards, so I’m going to tinker with the load until I see pressure or it starts to shoot.
The NRA’s American Rifleman showcased an interesting project this week — an upgraded Ruger American Rifle Predator in 6.5 Creedmoor. The video below shows how a laminated wood stock from Boyd’s Gunstocks was adapted for the Ruger. A Boyds Prairie Hunter model in gray laminate was selected. This was custom-bedded to the Ruger’s action using Brownell’s Acraglas.
All Ruger American Rifle models employ dual aluminum V-Blocks to support the action. These fit slots in the underside of the action. Boyds makes its own version of these V-Blocks which were installed in the Boyds stock to secure the action.
Project leader Joe Kurtenbach says the size, shape, and geometry of the Boyds V-Blocks is very accurate, so they fit the Ruger action well. To further support the action, Acraglas bedding compound was applied to the inside of the stock, after release compound was applied to the barreled action. With this DIY bedding job, the Boyds laminated stock is definitely an improvement over this original “Tupperware” factory stock.
DIY Bargain Hunter Upgrade
American Rifleman states: “The Ruger American has some great features—hammer-forged barrel, reliable action, crisp trigger — but many would not consider the molded, polymer stock to be among them. Luckily, there are aftermarket options to enhance the rifle’s utility and aesthetics. A durable, attractive stock from Boyds Gunstocks and some DIY action bedding, using Brownells Acraglas, is the next step in the precision-driven hunting rifle build.”
Choice of Gun and 6.5 Creedmoor Chambering
For this project, American Rifleman’s Joe Kurtenbach selected one of his favorite cartridges, the 6.5 Creedmoor. Introduced in 2007 by Hornady, the accurate, flat-shooting 6.5 Creedmoor has proven very popular with both hunters and tactical/PRS shooters. The Ruger American Rifle Predator was chosen for its affordable price, reliable action, and Ruger Marksman adjustable trigger.
In this video, Kurtenback explains how and why the 6.5 Creedmoor chambering and Ruger American Rifle were chosen for the Precision Hunter rifle build project.
If you are a gunsmith or work on firearms, you need to read this carefully. The Federal Government, acting through the Department of State Directorate of Defense Trade Controls (DDTC), has imposed significant new burdens on gunsmiths by expanding the definition of “manufacturing”. This is a big deal, as the Arms Export Control Act (AECA) and its implementing rules, the International Traffic in Arms Regulations (ITAR), require firearms “manufacturers” to register with DDTC and to pay a registration fee that (for new applicants) is currently $2,250 per year.
Previously, most small gunsmithing operations that did not export firearms were NOT subject to AECA/ITAR registration requirements. Now, by virtue of a DDTC “Guidance” ruling issued 7/22/2016, ordinary gunsmiths might be required to register as a manufacturer simply because they thread a muzzle or cut a chamber.
The NRA-ILA states: “DDTC is labeling commercial gunsmiths as ‘manufacturers’ for performing relatively simple work such as threading a barrel or fabricating a small custom part for an older firearm. Under the AECA, ‘manufacturers’ are required to register with DDTC at significant expense or risk onerous criminal penalties.” Read NRA-ILA Full Report.
Here is the key language in the DDTC’s “ITAR Registration Requirements – Consolidated Guidance” Ruling of 7/22/2016:
2. Registration Required – Manufacturing: In response to questions from persons engaged in the business of gunsmithing, DDTC has found in specific cases that ITAR registration is required because the following activities meet the ordinary, contemporary, common meaning of “manufacturing” and, therefore, constitute “manufacturing” for ITAR purposes:
a) Use of any special tooling or equipment upgrading in order to improve the capability of assembled or repaired firearms;
b) Modifications to a firearm that change round capacity;
c) The production of firearm parts (including, but not limited to, barrels, stocks, cylinders, breech mechanisms, triggers, silencers, or suppressors);
d) The systemized production of ammunition, including the automated loading or reloading of ammunition;
e) The machining or cutting of firearms, e.g., threading of muzzles or muzzle brake installation requiring machining, that results in an enhanced capability;
f) Rechambering firearms through machining, cutting, or drilling;
g) Chambering, cutting, or threading barrel blanks; and
h) Blueprinting firearms by machining the barrel.
Editor’s Comment: Does this mean that any stock-maker or stock supplier is an ITAR “manufacturer” under part 2(c)? Would installing a scope or accessory rail fall under part 2(a) as “equipment upgrading”? Would fluting a barrel be considered “manufacturing” under part 2(h)?
Impact of New Registration Requirements
As the NRA-ILA (Institute for Legislative Action) reads this, gunsmithing shops (even one-man operations) will now be subject to ITAR regulation though they export nothing: “These requirements apply, even if the business does not, and does not intend to, export any defense article. Moreover, under ITAR, ‘only one occasion of manufacturing … a defense article’ is necessary for a commercial entity to be considered ‘engaged in the business’ and therefore subject to the regime’s requirements.”
As a consequence, these new regulations may drive smaller gunsmithing services out of business: “DDTC’s move appears aimed at expanding the regulatory sweep of the AECA/ITAR and culling many smaller commercial gunsmithing operations that do not have the means to pay the annual registration fee or the sophistication to negotiate DDTC’s confusing maze of bureaucracy. [This is] likely to have a significant chilling effect on activity that would not even be considered regulated.”
Statutory Authority for Registration
The AECA’s statutory requirement for firearms manufacturers to register with DDTC is implemented in Part 122 of the ITAR:
§122.1 Registration requirements.
(a) Any person who engages in the United States in the business of manufacturing or exporting or temporarily importing defense articles, or furnishing defense services, is required to register with the Directorate of Defense Trade Controls under §122.2. For the purpose of this subchapter, engaging in such a business requires only one occasion of manufacturing or exporting or temporarily importing a defense article or furnishing a defense service. A manufacturer who does not engage in exporting must nevertheless register.

We know you guys like do-it-yourself (DIY) projects. And we also know that our readers like anything that helps a rifle sit more securely in the bags, and track better on recoil. Here’s a little accessory you can make yourself for pennies that will help rifles with conventional (non-benchrest) stocks ride the rear bag better.
This DIY Bag-Rider is simple in design and easy to make. The invention of Forum member Bill L. (aka “Nomad47″), this is simply a short section of PVC pipe attached to the bottom of a wood stock with a couple of screws. The back half of the PVC tube is cut at an angle to match the lower profile of the stock. Nomad47 painted the PVC Bag-Rider black for sex appeal, but that’s not really necessary.
In the top photo you can see Nomad47’s bagrider attached to a Savage varminter. In the photo below, the PVC bag-rider tube is fitted to an F-TR style rig with a green, laminated thumbhole stock. This rifle also features a Savage action with a custom barrel and “wide-track” bipod. (Note: to be legal in F-Class competition, the muzzle brake would have to be removed.)
All Ruger American Rifle models employ dual aluminum V-Blocks to support the action. These fit slots in the underside of the action. Boyds makes its own version of these V-Blocks which were installed in the Boyds stock to secure the action.
