B&T Unveils New Line of Modular Suppressors for Subgun Platforms

This week, B&T rolled out a new line of suppressors designed to redefine flexibility, control, and ease of use across three popular pistol-caliber platforms: 9mm, .40/10mm, and .45 ACP. These aren’t rehashes of older designs—they’re purpose-built tools for professionals and enthusiasts who demand rapid deployment, modular versatility, and fine-tuned backpressure management. Whether you’re running an MP5, an APC9, or a hard-hitting 10mm carbine, B&T’s latest offerings aim to deliver tailored performance in a compact, adaptable package.

Let’s walk through what makes this new series worth your attention—and how these suppressors set a fresh benchmark for submachine gun suppression.

SMG-M-9: Fast, Flexible, and Built for Modern 9mm SMGs

At the heart of the SMG-M-9 suppressor is a fusion of B&T’s Reduced Backpressure System (RBS) and their new Super Quick Disconnect (SQD) tri-lug mount. The SQD design is entirely one-handed—no twisting, no threading, no extra tools. Just press it on until it clicks, and you’re ready to go. When you’re done, a simple tab press removes it just as fast. It’s currently one of the quickest 3-lug mounting systems available, designed for rapid transitions in the field.

Compatible with standard tri-lug barrels found on platforms like the B&T APC9, SPC9, GHM9, and HK’s MP5 series, the SMG-M-9 takes modularity even further with a detachable RBS-compatible extension. You can run it short for a smaller footprint or add the extension for deeper suppression—depending on your specific needs.

User-Defined Configurations

Each unit ships with two interchangeable endcaps: one vented for reduced backpressure, and one sealed for optimal suppression. Combine that with the removable extension and you get four distinct setups from a single suppressor.

Key Specs for the SMG-M-9

• SQD Tri-Lug Mount: One-handed attachment/removal for 9mm SMGs

• Modular RBS Extension: Switch between compact and full-length configurations

• Dual Endcaps: Choose reduced blowback or tighter gas retention

• Four-in-One Setup: Tailor length and gas dynamics on the fly

• Caliber-Specific: Engineered for 9mm platforms with precision

SMG-M-40/10: Precision Adaptability for .40 S&W and 10mm

Sharing the same core design philosophy as the 9mm version, the SMG-M-40/10 is purpose-built for shooters running either .40 S&W or 10mm—two cartridges that share bullet diameter but differ in performance. This suppressor leverages the exact same SQD mount for rapid tri-lug attachment and uses a similarly modular approach.

Like its 9mm counterpart, the SMG-M-40/10 includes a detachable extension and dual endcaps, allowing shooters to adapt their loadout to the situation at hand. Whether you’re tuning for gas control or seeking the quietest possible signature, this suppressor can flex accordingly.

Key Specs for the SMG-M-40/10

• SQD Tri-Lug Mount: Quick-mount design compatible with .40/10mm tri-lug barrels

• Modular Length: Run short or full-length depending on mission needs

• Dual Endcaps: Toggle backpressure vs. suppression with ease

• All-in-One Platform: Four usable configurations in one unit

• Purpose-Engineered: Optimized for .40 S&W and 10mm firearms

SMG-M-45: Quick Attach Suppression for .45 ACP

For those running .45 ACP subguns or pistol-caliber carbines, B&T’s SMG-M-45 brings the same modular DNA and ultra-fast mounting interface to the table. This model is tailored specifically for the slower, heavier .45 round—delivering tuned performance for recoil management and sound suppression.

As with the other models, the SMG-M-45 features the SQD mount, a modular extension, and both vented and non-vented endcaps. The result is a plug-and-play system that adapts to your environment without requiring different cans or mount types.

Key Specs for the SMG-M-45

• SQD Tri-Lug Mount: Instantly attaches to .45 ACP tri-lug barrels

• Configurable Length: Remove or add the extension depending on use case

• Backpressure Control: Vent or seal endcap options for tailored gas dynamics

• Four Setup Options: Adapt suppressor profile and performance in seconds

• .45 ACP Optimization: Built specifically around the characteristics of .45 cal systems

Final Thoughts: A Suppressor Line That Actually Evolves With You

The new B&T suppressor family isn’t just about shaving decibels—it’s about meeting real-world needs with real-time adaptability. Whether you’re operating in tight quarters, training on the flat range, or working suppressed with high round counts, the ability to shift configurations without tools or downtime is a major win.

By giving shooters four usable suppressor setups in one, along with a dead-simple SQD mount, B&T has created a platform that not only simplifies logistics but elevates capability.
