Jerry Schmidt, an avid shooter and hunter from Montana, has created a tool designed to help install single-dovetail or double-dovetail rings on hunting rifles. Jerry’s invention, the Scope-Tru Alignment Bar (patent pending), is unique. Unlike most other alignment systems, this is a single, long precision machined rod with a pointed forward end. You work on one ring at a time, first setting the front ring in the dovetail and then setting the rear ring. The process is shown by Jerry in the video below.
Jerry explains: “The Scope-Tru Alignment Bar is a tool designed to install both standard ring/mount systems, and dual dovetail ring/mount systems. The tool provides significant leverage to turn the dovetail rings into their bases. By observing the pointer on the end of the bar, it is easy to align the ring with the center of the barrel, thereby assuring that the ring is installed at 90 degrees to the axis of the bore. Because the bar is a one-piece tool, it is possible to get the rings into nearly perfect alignment with each other, and near perfect alignment with the bore axis.”
The photos above show how the tool is used to install and align a set of standard hunting rings (with rear windage adjustment). You start with the front ring, rotating it 90 degrees in the dovetail, and then align with the center of the barrel. Next, slide the tool rearwards and loosely set the rear ring in place. With both rings adjusted correctly, the alignment tool will be perfectly centered and both rings with be subsequently squared at 90° to the bore axis. Schmidt says he can install conventional rings with this tool, tighten them to spec on a rifle scope, and there will be virtually no marks on the scope tube. (Of course this would require that the rings are extremely well made with no burrs or highspots on the trailing and leading edges.)
The Scope-Tru Alignment Bar is CNC-machined from TGP bar stock, and will be offered in both 1 inch, and 30mm diameters. The durable bar is designed for regular, long-term use by the professional gunsmith, the home gunsmith or “gun crank”, and retail or wholesale sporting goods store staff. The 1″-diameter, all-steel Scope-Tru is can be purchased for $135.00 plus shipping and handling. The version for 30mm rings AND a new combo 1″/30mm Scope-Tru tool are both in final development, and could be available in the near future.

Quite a few of our hunter friends have praised the DNZ Products (aka DedNutz) “Game Reaper” scope mounting system. This is a unitized one-piece base AND ring system. Because the rings are integral with the scope base, there’s no potential misalignment between the front and rear base. You also eliminate the need to keep separate rings torqued securely on an action-top rail. The rigid DNZ design has no moveable parts between the firearm and the scope.
Made of milled, anodized aluminum, the one-piece DNZ scope mounting system is one-third the weight of most other one-piece base and ring mounts and it can’t rust. For rifles with a Weaver or Picatinny-style base, we still advocate the use of Burris Signature Zee rings. However, if you are looking for a sturdy, low-profile set-up that attaches directly to the receiver, the DNZ system fits the bill. It would be a good choice for a walk-around varminter or a deer rifle. Because DNZ “Game Reaper” front and rear rings are precision CNC-machined, DNZ claims that it’s not necessary to lap the rings. We still recommend you inspect the ring edges and lightly debur as necessary. If you choose to lap the rings, do it gently as the inside should be very concentric already and you don’t want to grind through the anodizing.
One DNZ scope mount user, writing on huntingnet.com, comments: “I bought a pair of DedNutz for a Browning A-Bolt and a pair of Talley Lightweights for the same gun. I have to tell you that I think these DedNutz rings are some of the most rugged rings I have seen and yet are very lightweight. The [DedNutz] have a superior finish to the Talley lightweights … and they are better machined. I put a lapping bar on both and the Talleys needed it but not the DNs.” DedNutz scope mounts are are offered in 1″ and 30mm sizes, in matte silver, matte black, or Realtree Camo finishes.
DNZ scope mounts start at about $54.00 and can be purchased from MidwayUSA.com, or direct from DNZProducts.com. (You’ll probably find MidwayUSA’s prices to be considerably lower.)

Leupold’s Mark 4 riflescopes are highly respected for their quality of glass, user-friendly tactile turrets, and durability backed up by Leupold’s lifetime warranty. These scopes are favored by police and military shooters. Because of their popularity, Mark 4 scopes are in high demand and retailers maintain pretty high prices. We’ve worked with one of our sponsors to create a very attractive special discount on Mark 4 6.5-20x50mm LR/T M1 scopes, just for our readers.
Leupold 6.5-20x50mm Mark 4 with Leupold Tactical Rings for just $1375.99
Our sponsor DogHouse Outdoors has created a special package with a Leupold Mark 4 LR/T 6.5-20x50mm scope, plus Leupold tactical 30mm rings at a super-low price. These rings have an MSRP of $224.00. Through this special offer for AccurateShooter.com readers, you can get the Mark 4 scope, plus genuine Leupold Mark 4 30mm rings (either aluminum or steel), for just $1375.99. And shipping is FREE! Go ahead and comparison shop and you’ll see what a good value this is.
Choose either a mildot reticle or Leupold’s TMR® (Tactical Milling Reticle). Most tactical shooters seem to prefer the TMR, which has fine hash marks. However, in low light, some shooters say the older Mildot Reticle is easier to see.
This is a limited-time offer. DogHouse Outdoors plans to offer this $1375.99 pricing for the next three weeks, through the end of February, 2011. If you have been looking for a high-quality Leupold tactical scope, you should definitely check out this offer.
First Focal Plane, Mil-Mil Version Also Offered
Because most shooters actually are better served with a second focal plane reticle, and the vast majority of American shooters prefer MOA adjustments, the Mark 4 $1375.99 LR/T package scopes come with 1/4-MOA windage and elevation clicks with a second focal plane reticle. However, for those shooters who need a First Focal Plane (FFP) Reticle (for ranging at all magnifications), and mil-based clicks, DogHouse Outdoors is also offering a Mark 4, ER/T M5 6.5-20x50mm package. This features a FFP reticle, and turrets with 1/10 milrad clicks. The price, including Leupold Mark IV 30mm rings, is $1,775.99. That’s 24% off the normal list price (with the $224 rings). Again, this offer is limited in time. Get your orders in before 2/28/2011.

Stephen Ivey has engineered a set of gimbaled scope rings allowing up to 150 Minutes of Angle (MOA) of elevation. These rings have precision hinge pins front and rear allowing the entire scope to be tilted by a micrometer-controlled cam in the rear. This allows the scope to tilt upwards (in the rear) with the front ring as the axis while both rings remain parallel to prevent scope binding. The rear ring tilts to match the front while a cam pushes it up. Ivey also makes tilting +150 MOA Picatinny riser rails.
Ivey offers two scope-mounting products. First is the RT-150 Ring set (above). This has two, polished 30mm or 34mm 6061-T6 aluminum rings with bases to fit a Picatinny profile or mil-spec 1913 rail with standard 5mm cross slots at 10mm spacing. (Weaver installation requires extra cross-slots to be cut.) Total elevation is +150 MOA. The micrometer adjuster is graduated in true 1 MOA intervals, with 5 MOA of elevation change per rotation. This product costs $525.00 and requires at least 5-1/2″ length mounting base.
The newest product is the MSRR-150MOA Riser Rail, a pivoting 5.75″-long Picatinny-style rail that accepts Weaver-style clamping scope rings. This Adjusts from Zero to +150 MOA and raises the scope 1.45″ from the top of the action. The extra height provides clearance for large objectives when the unit is tilted for a full +150 MOA elevation. Cross slots are 5mm wide at 10mm (.394″) spacing. The $525.00 riser rail is made of 6061 T6 Aluminum hard-anodized black. Clamps are heat-treated steel. The micrometer thimble is marked for 1 MOA gradations, and provides 20 MOA per revolution.
The Ivey products are expensive, to be sure, but they are beautifully machined, and they offer unique capabilities for ultra-long-range shooters. With the +150 MOA units you have enough elevation to shoot at 2000+ yards! We like the idea of using the micrometer to dial within 1 MOA and then just using the scope turrets for fine-tuning.

We recently had a chance to test the new Chimera Titanium Rings from TacticalRifles.net. The Chimera Rings are “ultra-premium” items designed to compete with the very best tactical rings on the market. As you’d expect, they’re expensive. The 30mm Chimera Rings retail for $224.00 per matched set, including Torx driver. Though these fat boys are beefy in size, offering 7.5 square inches of clamping area per set (way more than most rings), they are very light weight. A medium-height, 30mm Chimera ring weighs just 84 grams (2.96 ounces).
The Chimera rings are precision-machined to exacting tolerances. We had our Mark, our in-house machinist, check them out and he was very impressed: “These rings exhibit beautiful fit and finish and are extremely tough. The fit of the ring bases on a Picatinny rail is perfect. I liked the radius shapes given to most of the surfaces. The front and back faces of each ring are standard flat planes, and the ring caps have a flat disc in their centers, but the remainder of the cap and the sides of the bodies are gently curved. This design requires sophisticated machining processes to pull off, but it looks good. The larger-than-standard heads on the cap hardware, 8-32 X #25 Torx, are another departure that looks well thought out. One danger this increased head size would present if the fasteners were threading into typical 6061 aluminum bodies would be the potential to over-torque and strip the threads with the larger #25 Torx wrench. However, since the titanium bodies have approximately double the tensile strength of 6061 aluminum this is not a problem.”
Assymetrical Tensioning by Design
The Chimera Titanium Rings employ an assymetrical clamping design. This should allow the rings to provide stronger clamping force with less chance of ring distortion. Here’s how they work. After placing the scope in the lower halves of the rings, you screw down the top halves on one side only (opposite the bolt head that clamps to the Picatinny rail). After the three Torx screws are tightened fully on one side, so that the top Ring half butts firmly on the bottom half, there will still be a small gap on the opposite side of the ring (see photo). Don’t worry — that is by design. Final torque is applied to the side with the gap. With the final tensioning done on one side only, the scope is less prone to twist. Furthermore, the manufacturer claims this design puts less stress on the scope tube during mounting.
We did fit the Chimera rings to a Leupold LRT 8-25x50mm scope with 30mm tube. Fit was excellent with no high or low points. With the rings installed as instructed, with one side first clamped flush and the opposite side then torqued to spec, the scope was very secure. On removal the Chimera rings left no visible marks on the tube. I can’t say that it would be a waste of time to lap these rings, but on our Leupold scope the fit was perfect, and the “grip” was uniform over the entire clamping surface.
Tactical Precision System TSR™ Rings TSR™ rings made by Tactical Precision Systems (TPS) have a clamping design very similar to the Chimera Titanium Rings. After placing the scope in the TSR ring set, you clamp down one side (of the ring tops) until metal meets metal. This then leaves a gap of 0.020″ on the other side. The TSR Picatinny 30mm 7075 Aluminum Medium Rings cost $82 in aluminum or $94.00 in alloy steel. The TSR rings are narrower than the Chimeras, and have two Torx bolts per side, rather than the three on the Chimeras.
M3 Hinged Scope Rings from American Rifle Company
An even more radical clamping system is employed by the new, patent-pendingM3 Scope Rings from The American Rifle Company. The top section of the M3 rings is attached with a hinge on one side. After placing the scope in the bottom section of the M3 rings, you swing the upper ring half into place over the scope tube. Then the clamping is done with two inverted (head-down) machine screws that actually pull the hinged ring section downwards. This is designed to put less stress on the scope than conventional rings. The axis of the screws is tangential to the scope tube. Sophisticated finite element analysis (FEA) was used to develop the “over the top”, tangential-clamping ring design. According to the manufacturer, this design evenly distributes clamping forces over the tube and “eliminates the damaging effects of [scope] bending”. The manufacturer claims that, with its rings, “no significant stress concentrations are present on the scope tube”. American Rifle Co. backs up these claims with a series of 3D stress analyses published on its website.

Brownells has added a new Professional Drill Jig to its collection of gunsmithing tools. The $194.99 jig, made by B Square, aligns hole-spacing for popular scope bases on most popular military bolt action receivers. According to Brownells, this jig: “aligns mount hole-spacing for Weaver, Redfield and Buehler bases on all Springfields, U.S. Enfields (not SMLE), Japs, Mausers, Remington 30s and similar bolt actions.” Brownells says this unit saves time and eliminates tedious measuring as it “automatically locates holes in reference to recoil shoulder, and aligns and spaces holes vertically on the centerline of the receiver.”
Brownells’ Drill Jig features all-metal construction. The jig bars, base block and top piece are gold-anodized aluminum while the bore arbor and “V” bushings are blued steel. For the $194.99 price, the Pro Drill Jig includes two bars (Mauser and Spgfld/Enf/Jap,), complete mounting assembly, and an interchangeable No. 31 drill bushing.
Editor’s Comment: In the past, we haven’t been particularly impressed with B Square consumer products, particularly B Square rails and rings, but with CNC machining these days, the Professional Jig should be a quality tool. Remember that Brownells offers a 100% Satisfaction Guarantee on everything it sells: “If you aren’t completely, 100% satisfied with any purchase you receive from Brownells, for any reason, at any time, return it for a full refund or exchange.

If you use mass-production ring sets, other than Burris Signature Rings or SAKO Optilock Rings (which both feature polymer inserts), you can benefit from lapping your scope rings. Lapping your rings, when done properly, with the right tools, can improve the fit of the rings, reducing bending forces and stress on the scope. Properly-lapped rings are also less likely to leave prominent marks on your scope tubes.
Forum member Boyd Allen is a strong advocate of ring lapping for factory-produced ring sets. He’s tried various lapping tools and he believes that the Kokopelli system is one of the best available. Custom crafted in Kalispell, Montana by John Werre, the Kokopelli lapping system combines a specially-machined lapping rod with patented flat-ended scope alignment bars.
Kokopelli Lapping Tool
John Werre, Kokopelli’s owner, explains why his lapping tool works better than most others: “No one was making a lapping bar that would lap anything more than the bottom half of the rings and they were made of rolled stock and only a very short stroke was possible, rapidly wearing out the bar due to the limited area of use. I did something entirely different. I designed the bar to be used with the top halves of the rings in place and utilizing a long stroke thereby distributing the wear over the entire 12″ length of the bar. Why just do half a job?”
John adds: “Another problem was that the lapping compound would readily scrape off the bar, slide around and wear the bar out as fast as the rings. I added the spiral groove to stop the scraping off of the compound and later changed to a much softer steel and put a very rough, but carefully designed, finish to accept the lapping compound, actually allowing the grit to be driven into the surface of the bar. The nasty, scruffy rough finish is full of grooves and valleys of a depth designed to ‘catch’ the very sharp lapping compound, imbedding it into the bar. You then will wear out what you’re trying to lap rather than wear out the bar at the same time. The spiral grooves also cannot catch on the edge of the scope rings as can one which has annular grooves cut perpendicular to the axis of the bar in separate rings. I have very good reasons for every unique feature of my tools. Every aspect has a valid design behind it.”
Kokopelli Scope Alignment Bars
Kokopelli’s patented scope alignment bars have flat ends and work differently than alignment bars which use pointed tips. Kokopelli came up with a flat-ended design because alignment bars with pointed tips can yield a “false positive”, meaning the points can touch when the scope rings are out of alignment. To demonstrate, try this simple experiment. Take two ordinary pencils. With one pencil in each hand, hold them parallel with the pointed (lead) tips touching. Now simply move the outboard end of each pencil, while keeping the tips touching. You can see instantly that the tips can touch even if the pencils are way out of alignment. The same thing can be true of scope alignment bars.
With the Kokopelli scope alignment bars, each bar is an exact cylindrical projection of the interior of each ring. When you bring the bars together, if they don’t mate perfectly, i.e. if there is any gap between the flat ends when the bars are touching, then you know you have an alignment problem. Kokopelli claims that misalignments as small as .002″ can be detected. John Werre explains: “The bars actually are a three-dimensional projection of each ring ‘hole’. You’re looking at a solid representation of the hole through the ring. Put one bar in each ring and you can then compare the axial alignment of the ‘ring holes’ to each other. If the ends match and are flat together you have reconstructed the bars into one [cylinder] and the alignment is PERFECT.” Below, in Figure 1, you can see rings that are out of alignment. In Figure 2 you can see rings that are properly aligned. Interestingly, the misalignment illustrated in Figure 1 did NOT show up with pointed ring alignment bars. This amount of misalignment can create up to 3/16″ of scope tube bending (depending on ring spacing).
The function of the Kokopelli lapping tool and alignment bars are described in greater detail on the Kokopelli website. The lapping tool and alignment bars are sold separately, or as part of Kokopelli’s complete Accurizing Kit shown below. The kit, which combines Scope Alignment Bars, Lapping Bar, pointer rod, and lapping compound in a fitted box, costs $84.50 for 1″ rings, or $91.00 for 30mm rings. For more info, contact John Werre at Kokopelli Products, 3820 Foothill Rd., Kalispell, MT 59901; phone (406) 755-3220. NOTE: Kokopelli has maintained the same prices since 2003. However, due to increased costs of materials, John Werre plans to raise his prices by mid-January, 2010. You can get current pricing by ordering soon.

On Sunday November 29th, the Ojai Valley Gun Club hosted its first-ever NBRSA-sanctioned, 600-yard Benchrest match. Ojai boasts a beautiful range in the Southern California foothills about 40 road miles from the coast. Many Pala Range regulars from the San Diego area were on hand, and some “big names” turned up for the event including Lou Murdica and 2007 NBRSA 600-yard Champion Don Nielson. In sunny but wildly changeable conditions (ranging from near-calm to 20 mph gusts), Don showed how it was done, winning the match with his 6.5×47 Lapua rifle.
Don finished first in ALL LG and HG categories except Heavy Gun score, where he placed second. In Light Gun class, Don shot a 2.207″ Agg for three, 5-shot targets (1.523″, 2.344″, 2.754″). Mind you this was in conditions where some pretty good shooters were off paper. Don said the secret was to shoot fast: “When it’s switchy, you can’t wait. I pretty much never stopped and never slowed down. Even for the 10-shot Heavy Gun Groups I think I was done in 30 seconds.” Second in Two Gun Overall was Brenda Hill. Brenda has established herself as one of California’s top F-Class and long-range shooters. At Ojai, Brenda was shooting a very accurate 6BRX rifle smithed by Leroy Johnson, jpgrifles [at] yahoo.com. John Crawford, Bruce Duncan, and Lou Murdica also all shot well in the difficult conditions.
On the firing line we found some very interesting equipment. John Crawford of the Bay Area had a beautiful Leonard-stocked gun chambered in 6mm Grendel. John is getting over 2900 fps with his 6mm Grendel, shooting 105gr Berger VLDs. He does have a long throat, but that is still impressive — 6BR velocities from the smaller-diameter Grendel case. Along with its gorgeous wood stock, Crawford’s rifle featured some very cool hardware. The trigger guard was radically skeletonized and anodized black. John’s scope was mounted with 4-bolt integrated scope rings/bases with 20 MOA built-in elevation. Produced by Marvin Pearson in Oregon, (360) 748-3429, these custom ring/bases were beautifully finished with radiused edges. Pearson’s ring/bases are available for 1″, 30mm, or 34mm tubes, with zero elevation “pre-load”, or up to 30 MOA of built-in elevation. Pearson charges $125.00 per set (plus shipping).
Crawford carried his 6mm Grendel ammo in compact 100-round ammo ammo cases from J&J Products. These cases pack big capacity in a relatively small footprint. There is enough clearance for long VLD-style bullets, but not so much extra “headroom” that the rounds can fall out if the box is inverted. John uses a piece of pink foam, cut to box dimensions, to protect his bullet tips when traveling. These 100-round J&J boxes measure 5.375″L x 5.375″W x 2.400″D and cost just $4.88 (J&J item BR-100).
Match director Barry Bluhm had a very nice ammo caddy that places ten loaded rounds up close to the loading port for fast cycling. Southpaw Bluhm keeps his ammo caddy on the right side, but the design would work equally well when used on the left side by a right-handed shooter.
Barry, who shoots a 6-6.5×47 for the most part, deserves a huge amount of credit for organizing this event. He spent many long hours building new target frames, and organized volunteers to man the pits and run the range. Without Barry’s dedication and hard work, this 600-yard match, hopefully the first of many registered events at Ojai, couldn’t have happened.

Surgeon Rifles has engineered new, heavy-duty scope rings with unique features. First, the rear ring comes with a bubble level integrated into the top half. This smart invention eliminates one other pricey accessory you’d otherwise need to add separately. The new Surgeon rings are made of high-grade 7075 T6 Aluminum so they are strong yet light. The “wide-body” design offers a full 0.950″ of clamping surface (front to back), secured by three vertical hex-head fasteners per side. The rings will be offered in a variety of heights, from .875″ to 1.125″, in both 30mm and 34 diameters. A 0.625″-wide steel version is planned for later release. Ring sets will cost $199.00 and that includes the bubble level.
Surgeon uses 9-axis machining to ensure exact alignment of ring center with ring base. Preston Pritchett, Surgeon’s owner, explains: “The bottom of the ring is machined at the same time as the bore for the scope on a 9 axis machine. This is done in one operation to ensure that the bore is parallel with the bottom of the ring. We checked another brand and found that they were off .0025″ in .625 inch. We checked ours and found it to be within .0003 in .950.” These rings are very carefully designed and crafted to align square on the rail. Many Weaver-style rings have a sloppy fit on the rail so they can clamp slightly differently from one installation to the next. Surgeon uses alignment pins to ensure its rings clamp properly: “The silver pins you see are 1/8 dowel pins that keep the clamp square to the ring and at the right height.”
For more info on these rings, or to place an order, visit SurgeonRifles.com, or call Preston Pritchett at (405) 567-0183. Surgeon plans to be shipping ring sets in various sizes within three weeks.

Forum member Jacob spotted this simple, but effective set of scope ring inserts on the Brownells’ Website. With these inserts, you can use a scope with 1″-diameter main tube in 30mm rings. Non-marring, matte black Delrin sleeves surround the scope tube so it can fit larger-diameter rings. Each sleeve comes in two parts for easy installation around your scope tube. This way you can use the same 30mm rings for all your scopes. Ring Reducers are sold as front/rear kits. Cost is just $19.99 for the 1″ to 30mm converters, item 084-000-091. There are also sets that reduce 30mm rings to 25mm, and 1″ rings to 3/4″ or 7/8″.
Note: These Brownells units simply function as plastic bushings. Unlike Burris Signature Ring inserts, they do not allow you to “pre-load” windage or elevation. If your rings are misaligned, the Brownells Ring Reducers won’t correct that problem.

Seekins Precision produces a wide variety of expertly-machined products such as scope rings, picatinny rails, and sling rails. Seekins products are priced competitively, but give up nothing in quality to some more expensive brands.
At SHOT 2009, Glen Seekins unveiled some cool, new products, including a new AR15 lower with many unique features. The Seekins SP223 lower features flutes on the magwell front face for improved grip, plus an enlarged triggerguard allowing use with gloves. The new lower takes standard milspec mags as well as MagPul P-Mags. It should be available in April 2009, with a price of about $350. Glen tells us that a Seekins AR upper design will follow “down the road.”
Seekins also announced new Remington 700 bottom metal. The Seekins R700 bottom metal assembly is made from 7075-T6 Aluminum allow — very tough stuff. The R700 is currently offered for .223 Rem, .308 (and other standard short action rounds), and .338 Lapua. A WSM version will be available soon. This bottom metal works with 5-round magazines, but Seekins will be offering 10-round .223 and .308 mags in the summer.

Made of milled, anodized aluminum, the one-piece DNZ scope mounting system is one-third the weight of most other one-piece base and ring mounts and it can’t rust.

However, if you are looking for a sturdy, low-profile set-up that attaches directly to the receiver, the DNZ system fits the bill.

I have to tell you that I think these DedNutz rings are some of the most rugged rings I have seen and yet are very lightweight. The [DedNutz] have a superior finish to the Talley lightweights … and they are better machined. I put a lapping bar on both and the Talleys needed it but not the DNs.” DedNutz scope mounts are are offered in 1″ and 30mm sizes, in matte silver, matte black, or Realtree Camo finishes.
