B&T APC Pro Features The B&T APC Pro runs on a gas piston operating system keeping fouling out of the action and off the bolt carrier compared to a direct impingement design. An adjustable gas valve lets the shooter dial in the system s reliability as fouling accumulates during long firing sessions or when running a suppressor which changes the gas pressure cycle back into the action. Chambered in .300 AAC Blackout the APC Pro is built to make full use of the cartridge s subsonic and supersonic versatility especially when suppressed. The 8.7 barrel is threaded 5/8x24 to accept a suppressor directly putting the rifle s piston system to work exactly as it was designed. The aluminum and polymer receiver is finished in black Cerakote for a durable low-glare surface that resists wear from repeated handling and holster or sling carry. A full-length Picatinny rail runs the top of the receiver giving shooters a stable repeatable platform for mounting a red dot or magnified optic. Flip-up front and rear sights provide a reliable backup sighting system if the primary optic fails or runs out of battery. An ambidextrous thumb safety and two-stage trigger keep the APC Pro fast and comfortable to run for both left and right-handed shooters and at 5.80 lbs with a 30+1 capacity the B&T APC Pro is built for shooters who want a compact suppressor-optimized pistol caliber platform.
