B&T USA RQD Tri-Lug HUB Mount – 9mm – Titanium & Stainless – SD-145712
The B&T USA RQD 9mm Tri-Lug HUB Mount (SD-145712) is a premium, high-strength interface designed to bring B&T’s legendary "Reduced Quick Detach" (RQD) technology to the universal suppressor market. In 2026, this mount serves as the premier bridge for owners of industry-standard 1.375x24 TPI (HUB) suppressors who want to utilize the rock-solid Tri-Lug system found on HK MP5, SP5K, and B&T APC9/GHM9 platforms. Unlike standard Tri-Lug adapters, the RQD system is engineered with a specialized locking collar that provides a faster, more secure "push-and-twist" attachment while maintaining a perfectly repeatable zero for precision sub-gun work.
To keep the system lightweight without sacrificing duty-grade durability, B&T utilizes a hybrid construction of Titanium and Stainless Steel. This ensures the mount can withstand the high-heat cycles of suppressed fire while adding minimal mass to the end of the firearm. The SD-145712 is a "Mainline" component, meaning it is built to the exact Swiss-derived specifications used by military and police units worldwide. It is designed to be threaded into the back of any HUB-compatible suppressor and can be semi-permanently secured using Rocksett. For the shooter who demands the most reliable, "no-fumble" 9mm mounting solution in 2026, the B&T RQD HUB mount remains the professional choice.
Includes: (1) B&T RQD 9mm Tri-Lug HUB Mount. (Requires a 1.375x24 "HUB" compatible suppressor for use).
