Product Description

The P2A PATRIOT 8.5" 40 S&W SBR + BYO Suppressor Package is a professional-grade Short Barreled Rifle layout custom-engineered from the ground up to serve as the definitive high-performance host for your personal .40 caliber pistol-caliber silencer collection. Chambered in the hard-hitting, snappy 40 S&W caliber, this legal NFA weapon platform replaces generic configurations with an architectural environment meticulously optimized to manage the severe backpressure and intense carbon fouling typical of running short heavy-mass blowback setups suppressed. By integrating an explicit, heavy-duty blowback bolt and specialized heavy buffer matrix, this platform flattens the sharp operational spike caused by restricted silencer gasses, keeping gas blowback away from your eyes and ensuring absolute tracking repeatability. Built on a dedicated or adaptable .40 caliber platform, it delivers the seamless ergonomics of a standard AR platform while driving premium close-quarters and mid-range tactical performance. Finished in a premium hardcoat anodized protective shield, this build ensures long-term operational field preservation from environmental degradation.

Every Build Your Own (BYO) Suppressor Package enables you to choose from our vast list of the most popular suppressors in the market. Whether you prioritize sound suppression, low back pressure, weight or a combination of all three - chances are we have the suppressor for you. No longer do you have to waste time and resources building and troubleshooting on your own or figuring out suppressor compatibility with other parts. Any model you choose, we will ensure the suppressor is mounted properly onto the firearm, checked for concentricity and test fired to ensure maximum performance.

• Concentric Thread-On Optimization: Precision-machined muzzle threads checked by hand for perfect shoulder tracking to ensure true alignment with suppressors, eliminating point-of-impact migration.
• Hard-Hitting 40 S&W Caliber: Achieves full powder burn inside tactical layouts, offering excellent middle-ground terminal ballistics between 9mm and 45 ACP, especially when tuning heavy 180gr subsonic rounds under suppression.
