SMG-M-40/10

Modular Innovation Meets One-Handed Attachment

Created for shooters who demand the next level of efficiency and adaptability, the SMG-M-40/10 seamlessly combines B&T’s signature Reduced Backpressure System (RBS) with a revolutionary Super Quick Disconnect (SQD) tri-lug mount. Whether you’re running a .40 caliber or 10mm firearm (both share the same projectile diameter), the SQD mechanism simply snaps onto your barrel—no additional tools or threading required. Remove it just as quickly by pressing the release tab, making it one of the fastest tri-lug attachments in the industry.

Modular Construction for Maximum Versatility

While fundamentally a single unit, the SMG-M-40/10 includes a modular RBS-ready extension that lets you toggle between a compact or full-length configuration. Drop the extension for a shorter, more maneuverable setup or keep it attached for superior noise suppression—perfect for changing mission requirements in real time.

User-Focused Customization

Each suppressor comes with two endcaps: one vented and one sealed. Opt for the vented cap to engage the RBS feature for reduced gas blowback, or select the non-vented cap when maximum sound reduction is paramount. Paired with the removable extension module, this system grants you four distinct setups, ensuring you can dial in your preferred combination of size, weight, and performance.

Key Features

• SQD Tri-Lug Mount – Effortless, one-handed attachment for any SMG or carbine with a tri-lug barrel in .40 S&W or 10mm.
