About
What it is, and why it matters
The B&T APC300 PRO is a Swiss gas-operated, semi-automatic carbine chambered in .300 AAC Blackout, part of B&T AG's APC (Advanced Police Carbine) family. It pairs a short 222 mm barrel with the platform's signature hydraulic buffer system for reduced felt recoil, fully ambidextrous controls, a folding and telescopic MBT stock, and a QDN NATO A2 suppressor interface. Feeding from STANAG-pattern 30-round Magpul magazines, it is optimised for compact, suppressed use with subsonic and supersonic .300 BLK loads.
B&T built its reputation on suppressors and the MP9 machine pistol before expanding the APC line across pistol and rifle calibres; the .300 Blackout APC300 leans into that heritage, purpose-built to be quiet with subsonic ammunition and a screw-on suppressor.
Manufacturer lists a weight of 3.2 kg including a 30-round magazine and sights (SKU BT-361563). The .300 BLK chambering allows the APC platform to run both subsonic (suppressed) and supersonic ammunition.
