Experience unparalleled performance with the San Tan Tactical® AR-15 Bolt Carrier Group for 6 ARC, featuring a premium nitride finish. Engineered for precision and reliability, this BCG ensures superior cycling and durability for your firearm. The nitride finish not only enhances corrosion resistance but also provides a smoother, harder surface for optimal function.

San Tan Tactical® AR-15 BCG

Why choose the STT AR-15 BCG? Because you deserve to upgrade your shooting experience with a bolt carrier group designed for serious enthusiasts who demand the best. Embrace the power and precision of San Tan Tactical® and take your AR-15 to the next level.

The enhanced bolt carrier’s flared rear minimizes tilt during recoil, enhancing reliability by optimizing key bearing surfaces. With fewer contact points, it reduces friction, and its increased mass ensures proper gas pressure and dwell time, improving extraction for suppressed or short-barreled rifles (SBRs).

Crafted to true MIL-Spec dimensions, the bolt is CNC ground post-heat treatment for a precise fit. San Tan Tactical® bolts adhere to the highest tolerances, with critical dimensions held to .0005”. The “trumpet” area behind the gas rings is precision-ground after heat treatment to reduce carbon buildup, simplifying cleanup and extending lifespan.
