You may have heard the phrase “blueprinting an action”, but do you know what that really means? Do you know what operations are done to an action during the blueprinting process? To help you understand, gunsmith Bill Marr of RifleShooter.com has created a helpful article showing a Rem 700 blueprinting job start to finish. This article spotlights how the procedures can be done with manual tools. Bill, who runs 782 Custom Gunworks Ltd., can also perform many of these operations with modern automated machinery. In fact, Bill has written a follow-up article on Truing a Rem 700 receiver with a Lathe.
Bill explains: “Blue-printing, or truing a rifle action, ensures the receiver face, threads, lugs, bolt lugs, and bolt face are square to the center line of the receiver.” In Bill’s informative article, Bill shows how he blueprints a Remington 700 short action receiver with .308 Win bolt face. He covers the following procedures step by step:
Action Disassembly
Ream Minor Diameter of Receiver Threads
Square the Receiver Lugs
Square the Face of the Receiver
Lap the Bolt Lugs
Square the Bolt Face
Bill employed a variety of tools from Brownells to complete the blueprinting job, including: Remington 700 Armorer’s Kit; Manson Receiver Accurizing Kit; Bolt Lapping Kit; Bolt Face Truing Tool; Manson Receiver Ring Facing Cutter; Multi-Vise with Jaw Pads; Silicone Carbide Abrasive; and Do-Drill Cutting Oil.
Highlights from the Rifleshooter.com article:
1. Chasing the Threads
We use the bushings to guide the receiver tap. This chases the threads and ensures they are square.
2. Truing the Receiver Face
Using the receiver facing tool, the front of the receiver is trued. The tool is placed over the tap and turned by hand. We used Do Drill to lubricate it.
3. Lapping the Lugs
The bolt lapping tool screws into the front of the action and applies rearward pressure on the bolt face. A little bit of lapping compound is placed on the front of the receiver lugs. The bolt handle is then raised and lowered repeatedly. Note — it is critical that we do not get any lapping compound on any other surfaces.
4. Truing the Bolt Face
On this bolt, the central part of the bolt face was low. After the truing operation, this Rem 700 bolt face is now completely square to the action.

Remington is closing its Ilion, New York firearms factory after 208 years of operation — more than two centuries. Over 300 jobs have been lost with operations moved to Georgia. Get the full story from this Fox News video. Ilion’s Mayor, John Stephens, is interviewed. He notes that the factory closure will have a huge negative impact on the city’s tax base and budget and the “nostalgic and historic loss is a bigger burden to bear”. City, county, and state officials are now “actively working on a re-use for the facility”.
Founded in 1816, Remington Firearms remains one of the United States’ largest domestic producers of shotguns and rifles. Several of the company’s strategic products will be manufactured in Georgia. The new headquarters will also become home to an innovative research and development center.
Remington Has a Storied History
Founded in 1816 by Eliphalet Remington in New York, Remington is the oldest continuously-operating gun manufacturer in the United States. Prior to the re-organization, Remington sold more sporting rifles and shotguns than any other American company. Remington has developed more cartridges than any other U.S. company. And for decades Remington was the only American company that sells firearms AND ammunition under its own name. Now Remington ammo is produced in Arkansas, as a separate business. Remington’s ammunition business was acquired by Vista Outdoor, parent of CCI, Federal, RCBS and other major shooting/outdoor industry brands.

The Model 700 series of bolt-action rifles have been manufactured by Remington Arms since 1962. All are based on basically the same centerfire bolt action. They are typically sold with an internal magazine depending on caliber, some of which have a floor-plate for quick-unloading, and some of which are “blind” (no floor-plate). The rifle can also be ordered with a detachable box magazine. The Model 700 is a development of the Remington 721 and 722 series of rifles, which were introduced in 1948.
The Remington 700 is a manually-operated bolt action with forward, dual opposed lugs. It features “Cock On Opening”, meaning the upward rotation of the bolt when the rifle is opened cocks the firing pin. A cam mechanism pushes the firing pin’s cocking piece backward. The bolt face is recessed, fully enclosing the base of the cartridge. The extractor is a C-clip sitting within the bolt face. The ejector is a plunger on the bolt face actuated by a coil spring. The bolt is of 3-piece construction, brazed together (head, body. and bolt handle). The receiver is milled from round cross-section steel.

According to TimneyUSA, starting this month (July 2023) “all Remington Model 700 rifles will come standard with Timney triggers”. Remington’s Alpha 1 and Police Rem 700s will come with the Timney Elite Hunter trigger while ALL other new Rem 700 rifle models will ship with Timney’s new Impact 700 trigger.
The impressive Impact 700 trigger is the newest trigger in Timney’s extensive line of Remington 700 triggers. American-made by skilled craftsman, these Impact triggers enhance Remington production rifles and are a good choice when purchased separately for a Rem-clone rifle.
Timney fabricates the new Impact trigger the right way — parts are machined from billet steel. There’s no skimping with metal injection molding, rolled, or stamped parts. Timney hand-assembles, tests, and calibrates each Impact trigger. Yet they are offered at a very affordable price: $124.99 MSRP.
This new trigger has a factory set pull weight of 3 – 4 pounds (non-adjustable) that provides a crisp, clean break. This new Impact trigger features Timney’s Sear Engagement Adjustment Lock design (SEAL’d) for consistent performance.
The Impact 700 is the next evolution for a quality, drop-in replacement trigger for the iconic Remington Model 700 rifle. This Timney Impact trigger makes a Remington 700 production rifle more desirable than ever before, as the Rem 700 series now boasts one of the best triggers you can get on a factory rifle. This new Impact trigger is also a very good, affordable option for Rem-clone rifle owners.
Timney states: “Timney was asked to provide a Timney 700 Replacement Trigger that does not compromise on quality. Timney listened. Timney delivered.”

For today’s Sunday GunDay story, we look at the legendary Remington 700, perhaps the most popular American bolt-action rifle of all time. After covering the history of the Rem 700 rifle, we provide an inside look at the Rem 700 through a series of cutaway animations. Then we explain how gunsmiths can enhance a Remington 700 action through “blueprinting” procedures.
Remington 700 Origins and History
After World War II, Remington Arms engineer Mike Walker began designing lower-cost alternatives to the Model 30, which resulted in the Model 721. These used a cylindrical receiver produced from cylindrical bar stock that could be turned on a lathe, rather than machined in a series of milling operations, which significantly reduced the cost of production. Further developments of the basic 721 action under the direction of Walker produced the Model 722 and Model 725, and ultimately in 1962, the Model 700.
Walker sought to increase the accuracy of the rifles, by utilizing tight tolerances in the chamber and bore, a short leade, and a very fast lock time. Like the earlier 721, the Remington 700 action was designed for mass production. Remington initially produced two variants of the Model 700, the ADL and BDL, in both long- and short-action versions. In 1969, Remington introduced upgrades for the rifle, including a longer rear bolt shroud, a jeweled bolt, and improved stock finishing. Four years later, production of left-handed Rem 700s began, to compete with the Savage Model 110, at that time the only major American-made left-bolt rifle.
Other Rem 700 versions include the titanium receiver 700ti, the 700 SPS (which replaced the ADL in 2005), and the CDL model. In addition to its development as a hunting rifle, the Model 700 also provided the basis for military and police sniper rifles, starting with the M40 rifle in 1966, which was initially ordered by the U.S. Marine Corps. The U.S. Army adopted the M24 Sniper Weapon System in 1986.
The Remington 700 is sold in both short action and long action variants. This photo is from the Big ED YouTube video comparing the two action lengths.
The Remington 700 is a manually-operated bolt action with two forward dual-opposed lugs. The bolt face is recessed, fully enclosing the base of the cartridge, The extractor is a C-clip sitting within the bolt face. The ejector is a plunger on the bolt face actuated by a coil spring. The bolt is of 3-piece construction, brazed together (head, body and bolt handle). The receiver is milled from round cross-section steel.
Chassis Systems for Remington 700s
With the popularity of the Remington 700 series rifles, and the availability of Rem 700 barreled actions by themselves, many companies have created after-market chassis systems. This GunMan YouTube Video reviews five modern chassis systems configured for Remington 700 barreled actions. Modular chassis systems have become particularly popular with PRS/NRL competitors.

Here is what high-end hunters have been requesting for years — an ultra-lightweight mag-fed action with Benchrest-grade smoothness, engineering, and craftsmanship. BAT Machine has just introduced two impressive new aluminum/steel hybrid repeater actions — the Bumblebee (short action) and the Vampire (long action). These are REALLY light. BAT states 23.8 ounces for the Bumblebee, and Alex Wheeler reports the Vampire is 25.3 ounces. So you get titanium-class weight savings without the titanium hassles.
Both the Bumblebee ($1699 MSRP) and the Vampire ($1765 MSRP) are aluminum/steel designs with integral recoil lugs and +20 MOA Picatinny rail segments. Though they are flat-bottom actions, both are designed to fit most Remington 700-pattern stocks. Gunsmith Alex Wheeler says: “This action shape should be very stable in the bedding — you just need to square up the inlet.”
Both the Vampire and Bumblebee actions feature a modular bolt. BAT does the modular bolt differently than anyone else, and very cleverly. This design allows easier bolt face changes and spring changes. Internal maintenance is also easier. Bat bolts also run super smoothly. Alex Wheeler reports “the Vampire action is very smooth — it feels just like BAT’s all-steel actions.”
Vampire action photos courtesy WheelerAccuracy.com. The Vampire fits a 4″-long CFE-09 magazine box.
Alex Wheeler got one of the first Vampire actions, and he was impressed. This is a long-action repeater, with standard or Magnum bolt. Alex says the mating of steel and aluminum was superb: “I have checked it for straightness and lug contact. It’s very good. I’m impressed with how straight they got this insert.”
Bumblebee Action — State-of-the-Art Lightweight Hunting Action
If you are seeking a very lightweight action with Benchrest-quality smoothness and precision fit/finish, consider the Bumblebee. Weighing under 24 ounces, this new Bumblebee short action may be perfect for hunters, varminters, and tactical shooters who desire a light weight, premium quality action. The new Bumblebee is designed to use 700 Short Action bottom metal. Combining steel and aluminum, the Bumblebee combines 4140 Chromoly Steel and 7076-T6 Aluminum to achieve strength and rigidity at a weight rivaling titanium. According to BAT, the Bumblebee’s advance design makes it “31%-42% stiffer than light weight steel actions and over 130% stiffer than round Titanium actions.”
Bumblebee Action Features and Specifications:
— Action weight is 23.8 oz. as configured in photos (11.4 oz. lighter than BAT VR/TR actions)
— Weight comparable to Titanium actions after including Picatinny rails, recoil lugs, and fasteners
— 31%-42% stiffer than lightweight steel actions and over 130% stiffer than round Titanium actions
— Action body made with aircraft-grade billet 7075-T6 Aluminum and hardened 4140 Chromoly Steel
— Integral +20 MOA Picatinny two-section rail standard
— Modular bolt for lower cost bolt face changes
— .070″ firing pin diameter for maximum accuracy and reliable ignition
— Standard medium aluminum bolt knob, 5/16-24 thread
— LiFe Melonite-treated firing pin, bolt and shroud for smooth bolt movement and low maintenance
— Extended extraction cam for smooth bolt opening
— Uses Remington 700 SA trigger components and bottom metal
— Right-hand and left-hand versions
— Barrel tenon is 1.062 x 18 tpi (CLICK HERE for blueprint)

Turn a Rough Factory Rifle into an Accurate Hunting Rig
Kiwi Nathan Foster has produced a good video for hunters with “under-performing” Remington Model 700 rifles. In this video, Nathan helps a client turn a badly-behaving Rem 700 into a reliable tack-driver. A customer had sent Nathan this rifle to rectify stubborn copper fouling. After bedding the rifle, the customer discovered that the rifle produced terrible groups due to the stubborn bore.
Nathan told us: “This was a grand opportunity to study what can go wrong with the M700 rifle with regards to both do-it-yourself work and flaws within rifle production. To help structure the video, we used the chapters of our Accurizing Book as reference steps for the video. This footage also works in conjunction with our free Remington bedding tutorials on YouTube.
Those who have watched the full M700 Troubleshooting video say this is one of the most helpful videos yet released on problem-solving with a factory hunting rifle. This video is especially helpful for those just getting into the accuracy game, as it walks the viewer through the basics of rifle tuning, then proceeds to more advanced methods of improving a badly-behaving rifle.
This video focuses on the Remington M700 and Rem clones, such as the Bergara rifle. However the lessons and techniques in the video can apply to any type of bolt-action rifle suffering heavy copper fouling. The video features detailed footage of barrel break-in and barrel-lapping procedures. These procedures may be beneficial for rough factory barrels. IMPORTANT! AccurateShooter.com recommends different break-in and maintenance regimes for custom, hand-lapped premium barrels — be conservative with fine custom barrels. Our best custom barrels have all shot superbly with minimal break-in and zero use of abrasives during break-in.
