The B & T APC9 PRO SBR w/ Glock Lower & Rare Breed FRT is a premium, factory-integrated National Firearms Act (NFA) Short Barreled Rifle engineered to merge Swiss submachine gun ergonomics with the ubiquitous Glock magazine ecosystem. This elite, highly specialized tactical platform features a pre-installed Rare Breed Triggers FRT-AP3™ forced reset system to achieve an incredibly fast, mechanically assisted cycle speed while remaining legally semi-automatic. Built on B & T's legendary hydraulic-buffered action, the weapon dramatically dampens felt recoil, allowing for maximum control and flat muzzle tracking during rapid-fire strings. It features a 6.8-inch cold hammer-forged barrel complete with an integrated 3-lug muzzle geometry for instant QD suppressor mounting, alongside fully ambidextrous M4-style controls and a dual auto-folding charging handle. Outfitted with the premium MBT side-folding and telescoping stock, this specific package feeds natively from standard double-stack 9mm Glock magazines and ships with one 33-round extended magazine.
