We received many requests from our Precision Rifle Shooting Community for a no taper Straight Contour Stainless Steel barrel.  As a result we worked with Proof Research and they created the ACCURACY contour just for us.  This is a 1.25″ straight barrel.  There is no taper whatsoever.  This is a straight 4kg 26″ finished length barrel all manufactured by Proof Research to their exacting standards and specifications for a world class Match Grade barrel.

• 6mm
• 7.5 Twist
• 26″ Length
• Accuracy – Straight Barrel Contour
• 4kg unfinished weight

When we joined with Lawrence Barrels in 2012 we acquired 15 years of experience in manufacturing precision steel rifle barrels. We make our stainless steel barrels in-house with an absolute commitment to extreme accuracy and quality. We start with double stress-relieved 416R stainless steel, a pre-hardened chromium stainless steel ideally suited for use in precision, match-grade rifle barrels. 416R was specifically designed by engineers in collaboration with barrel makers and rifle manufacturers to provide the consistency, high quality and durability the firearms industry demands.

416R is our stainless steel of choice because it has the following characteristics:

• Excellent machinability for gun drilling and reaming, plus exceptional polishability for uniform lapping—a must for bore accuracy.
• A homogeneous microstructure which responds to heat treatment providing a uniform hardness along the length of the bar, necessary for accurate rifling to precise groove dimensions.
• An optimum combination of high tensile strength along with adequate toughness to withstand typical chamber pressures encountered during firing.

Our 416R arrives at our factory in long lengths and is then cut to finished barrel length. The barrels are then drilled, contoured and reamed to the bore diameter of the cartridge for which they are to be chambered. The barrels are then rifled and lapped and inspected with a bore scope.

Accuracy International Chassis Systems bring ergonomic and functional benefits that are delivered with degrees of modularity and configurability that cannot be achieved with any traditional stock. AI pre-fits are available for both 27mm and 30mm tenon sizes.

PROOF Research Pre-Fit Accuracy International barrels are quick and easy to install on the AI platform and require no specialized gunsmithing. Our drop-in barrels for the AI chassis come threaded and chambered in a variety of different lengths and twist rates.

Long-Lasting

Excellent erosion wear characteristics and corrosion resistance.

Extreme Pressure Resistance

An optimum combination of high tensile strength along with requisite toughness to withstand extreme chamber pressures encountered during firing.

At PROOF Research we’re proving carbon fibre-wrapped rifle barrels aren’t just a lightweight alternative to traditional steel rifle barrels, but that they provide superior performance, including extreme accuracy, unprecedented durability and increased barrel life. By combining our unique manufacturing process with advanced technology composite materials and thermo-mechanical design principles, we’ve accomplished what others have failed to do in the past—match-grade carbon fibre rifle barrels that weigh a fraction of traditional steel rifle barrels while compromising nothing. They’re not just lighter—they’re better.

Our patented manufacturing process begins with full-profile, match-grade 416R stainless steel barrel blanks that are made in our firearms division. These blanks are then turned down to a significantly reduced profile greatly reducing weight. This reduced contour barrel is then wrapped with high-strength, aerospace-grade carbon fibre impregnated with a proprietary matrix resin developed by our advanced composites division, PROOF Research ACD.

The aerospace-grade carbon fibre we use has a specific strength up to 30 times that of stainless steel and a specific stiffness up to 7 times greater than steel. But strength and stiffness are only part of the equation. Heat conductivity and thermal expansion are also of paramount importance when developing a match-grade carbon fibre barrel. Our helical wrapping pattern favours the longitudinal thermal diffusivity of the carbon fibres (along the length of the barrel) allowing them to more efficiently dissipate heat emanating from the barrel rather than insulating it.

THE ONLY CARBON FIBER-WRAPPED RIFLE BARREL APPROVED FOR USE BY THE U.S. MILITARY.

Because our rifle barrels are engineered for thermal performance, they also move heat very effectively through the wall (thickness) of the barrel, greatly increasing heat transport and resulting in barrels that cool faster and maintain accuracy over longer sessions of fire.

The end result is an aerospace-grade, high-fibre content composite barrel that is stronger, lighter, as accurate as the finest precision steel barrel, and maintains its accuracy in the most demanding environments.

We didn’t invent carbon fibre-wrapped rifle barrels. We just perfected them.

• Up to 64% lighter than traditional steel barrels of similar contour

• Match-grade accuracy

• Improved heat dissipation for cooler and longer lasting barrels

• No point-of-impact shift during high-volume fire

• Reduced harmonic barrel vibration

• Unprecedented durability
