Frequently Asked Questions

How does the B&T APC9 SD make supersonic ammunition subsonic?

The B&T APC9 SD features a specially designed ported barrel. These ports bleed off excess gas pressure from standard 115gr supersonic 9mm ammunition, slowing it down to subsonic velocities before it exits the barrel, thus achieving quiet suppressed operation without special ammo.

What is the purpose of the hydraulic buffer in the B&T APC9 SD?

The hydraulic buffer system is a key component in the APC9 SD's direct blowback operation. It effectively mitigates recoil and controls 'bolt bounce,' a common issue in blowback systems, leading to a smoother, flatter shooting, and more controllable firearm.

What makes the Print-X SD suppressor unique?

The Print-X SD suppressor is notable for its construction using 3D-printed titanium. This advanced manufacturing technique allows for significant weight reduction compared to traditional suppressors while maintaining durability and performance, representing a leap in suppressor technology.

Can the B&T APC9 SD accept different types of magazines?

Yes, the modularity of the B&T APC9 SD platform includes interchangeable lower receivers. This allows users to configure the firearm to accept various magazine types, such as those designed for B&T, Glock, Sig P320, and even MP5 pattern firearms.
