B&T RQD 9MM TRI-LUG HUB MOUNT

Description

The B&T RQD 9mm Tri-Lug HUB is a suppressor mounting adapter built for shooters running B&T or HK-spec tri-lug 9mm barrels who want to attach a HUB-compatible suppressor without adapting or replacing their existing barrel. Rather than threading onto a muzzle directly, this adapter bridges the tri-lug interface on the barrel to any suppressor built around the 1.375×24 TPI HUB standard, which has become a broadly adopted specification across multiple suppressor manufacturers. That compatibility matters practically: it means the adapter is not locked to a single suppressor brand, so a shooter can change suppressors later without swapping out the mount.

Construction uses titanium and stainless steel components. Titanium carries the mass penalty down relative to an all-steel adapter, which is relevant at the muzzle end where added weight affects balance and can affect suppressor alignment under recoil. The stainless steel elements handle the wear surfaces and threading where durability under repeated cycling is more important than weight savings.

Installation is straightforward: the adapter threads into the suppressor’s HUB mount and is seated with a spanner wrench. For users who want a more permanent setup — a dedicated host, for example — the assembly accepts Rocksett or similar thread-locking compounds to prevent any rotational movement during sustained fire. The spanner-wrench attachment method also means removal is still possible if the end user later chooses to reconfigure, unlike permanently pinned or welded solutions.
