B&T Firearms APC Pro 5.56 NATO 16.5" 31-Round Threaded Barrel Carbine

The B&T Firearms APC Pro 5.56 NATO 16.5" 31-Round Threaded Barrel Carbine is a Swiss-engineered platform purpose-built for law enforcement tactical units, military designated marksmen, and serious civilian shooters who demand reliability under pressure. With roots in European precision manufacturing, this compact carbine bridges the gap between modularity and durability, delivering consistent performance in CQB, patrol, and designated marksman roles where barrel length and weight discipline are critical trade-offs.

The 16.5-inch threaded barrel provides velocity optimization for 5.56 NATO while remaining compact enough for vehicle operations and confined-space engagements; the threaded muzzle accepts industry-standard suppressors and compensators to tailor ergonomics and signature reduction. At 13.56 pounds fully configured, the APC Pro balances reciprocating mass and control without sacrificing the durability expected in duty-grade platforms. The 31-round magazine capacity ensures tactical flexibility in high-volume scenarios, while the proven APC operating system cycles reliably across military-spec and commercial ammunition variations without premature wear.

Law enforcement agencies value this carbine for its compact footprint, modular rail systems, and compatibility with standard 5.56 optics and accessories—critical in departments standardizing on AR-pattern platforms. The threaded barrel opens pathways for sound suppression in low-light entries or training scenarios where noise discipline matters. Civilian shooters and competition participants benefit from its predictable recoil impulse and repeatability across extended shooting sessions. Installation of optics, lights, and vertical grips follows standard Picatinny mounting conventions; users should verify local regulations regarding barrel length, magazine capacity, and suppressor legality before purchase.
