Product Details

BRT 14" OPTIMUM MPC Barrel

This length fulfills the need for a barrel that can be pinned and welded up to a non-NFA length using some of the longer muzzle devices available. Also a perfect match for 13" long hand guards.

Any device 2.67" or longer will work without using shims.

BRT Gas Drive

The BRT Gas Drive provides exceptional smoothness with extreme reliability. The gas port size controls how much pressure is delivered to the action and therefore how much gas drive is available to cycle the action. Proper balance is critical to the reliability and longevity of the system.

BRT barrels are designed for reliable use with and without a suppressor attached. The results are an balance of wide reliability margin, smooth operation and seamless suppressor compatibility with near zero "gas to face" issues.

  • Buffer Recommendations
    • Unsuppressed: H or CAR, VLTOR A5H0
    • Suppressed: H2, VLTOR A5H2

BRT OPTIMUM MPC Profile

The BRT OPTIMUM Multi Purpose Carbine profile combines art and science to maximize performance. While its smooth transitions and gentle tapers are organically inspired, the end result is backed by extensive analysis, design and testing. The profile is thicker near the chamber for better heat resistance and uniform thermal performance, tapering toward the muzzle to reduce weight and improve balance. The handguard cap shoulder is contoured to the .750" diameter gas block journal, which is dimpled for simple installation of a BRT MicroPin gas block. The end result is a midweight, fast handling barrel with improved consistency across various loads and firing schedules.

Mid Length Gas System

The Mid length gas system allows optimum performance from 14" barrels. The gas system length controls the timing of the gas cycle and overall gas drive available. Existing gas systems, while functional, don't offer the balance of factors to allow exceptionally smooth cycling with maximum reliability. The BRT design balances these factors to optimize gas system performance under extreme conditions.

Suppressor Ready 1/2"-28 Muzzle Thread

Precision cut threads are specified to a tighter tolerance and better bore alignment than standard threads, while maintaining compatibility with all common muzzle devices.

Match Grade Blank

A great shooting barrel starts with a superior blank. Certified bar stock is deep hole drilled and precision reamed. The blanks are then CNC honed on state of the art equipment to produce a uniform bore diameter with less than .0002" variation from chamber to crown. This level of uniformity and roundness exceeds what is generally possible even with hand lapping.

6P Rifling 1/7 Twist

6P rifling improves upon conventional rifling in several important ways. The hybrid poly groove design produces less bullet deformation allows better exterior ballistics. In addition, the sides of the lands are sloped and blended to reduce fouling and further reduce bullet jacket stress. The optimized land-groove ratio minimizes engraving forces while boosting projectile velocity.

The 1/7 twist rate stabilizes the heaviest projectiles in extreme environments, while producing excellent performance from lighter training and varmint projectiles.

4150 CrMoV Barrel Steel

This is the same grade of steel specified by the US military for nearly all small arms barrels due to its excellent heat resistance and uniform grain structure. The addition of Vanadium and increased Carbon sets this alloy apart from the steels commonly used to make barrels offered in the commercial market. This steel is inspected and certified to meet strict requirements of chemistry and composition at the mill before continuing on to be made into a barrel blank.

Melonite QPQ

BRT barrels are treated inside and outside with the corrosion and wear resistant QPQ process. More than a surface finish, this treatment converts the outer surfaces of the steel into a hard composition with similar properties to hard chrome plating, but without any dimensional changes. This new surface improves extraction and velocity while resisting fouling and corrosion.

5.56 NATO chamber

This allows maximum compatibility wits all commonly available ammunition types, including military 5.56, brass cased .223 and steel cased .223. A properly dimensioned 5.56 NATO chamber offers maximum reliability and ammunition compatibility, while giving up almost nothing compared to SAAMI .223 Remington or .223 Wylde chambers.

M4 Barrel Extension

This includes enlarged and lengthened feed ramps to ensure smooth feeding of all ammunition types. The barrel extensions are finished separately from the barrels during their QPQ process to ensure critical parameters are unaffected. They are joined during final assembly, ensuring excellent longevity and performance.
