SMG-M-45

Rapid One-Handed Mounting Meets Modular Adaptability

Specifically conceived for .45 ACP platforms, the SMG-M-45 merges B&T’s revolutionary Super Quick Disconnect (SQD) tri-lug mount with the acclaimed Reduced Backpressure System (RBS). Attaching to any in-spec tri-lug barrel in mere seconds, this advanced can boasts effortless one-handed operation—simplifying on-the-fly transitions and quick takedowns. Whether you’re running a .45 ACP submachine gun or a pistol-caliber carbine, the Print-X SQD-M45 ensures an unrivaled blend of fast handling, flexibility, and reliable performance.

Modular in Every Sense 

Although it ships as a single compact suppressor, the SMG-M-45 includes a removable RBS-compatible module. Keep it off for a sleeker, lighter profile, or attach it for enhanced noise mitigation. This modular approach allows you to adapt the system to the demands of any mission, from close-quarter maneuvers to extended range training.

Customize Your Backpressure 

Each SMG-M-45 arrives with two specialized endcaps—one vented and one sealed—empowering you to fine-tune your suppressor’s internal gas dynamics. Opt for the vented cap to reduce blowback on rapid-fire strings, or choose the non-vented cap for deeper sound suppression and increased stealth. Paired with the modular extension, you can create four distinct setups to match your preference for minimal bulk, maximum hush, or anything in between.
