B&T APC223 .223REM 264mm /10.4" Barrel Ambi Non-Reciprocating Folding Stock Details

The APC223/556 utilizes a piston operating system optimized for use with a suppressor and can be regulated by way of an adjustable gas valve. It can be tuned as the weapon becomes increasingly fouled due to heavy firing schedules or prolonged use with a suppressor. The piston design not only increases the reliability of the operating system in adverse conditions, but also traps less gas within the system. What gas remains is expelled forward of the shooter, making the platform not only more comfortable to shoot suppressed, but it’s also healthier for the shooter.
