B&T RQD 9mm Tri-Lug HUB Mount

The B&T RQD 9mm Tri-Lug HUB Mount lets a HUB-compatible suppressor attach to any B&T/HK-spec tri-lug 9mm barrel (B&T part no. SD-145712). It is machined from titanium and stainless steel components and is fully compatible with 1.375×24 TPI (1.375-24) HUB-threaded suppressors on the market today. It threads directly into the base of the serialized suppressor tube and is tightened with a spanner wrench; end users who want a more permanent setup can attach it with Rocksett or another thread-locking compound. This is a focused accessory for shooters running a tri-lug-equipped 9mm host.

• It threads directly into the base of the suppressor tube and tightens with a spanner wrench.
• It can be semi-permanently attached with Rocksett or another thread-locking compound if the end user prefers a fixed setup.
• It is sized for 9mm, matching tri-lug pistol-caliber hosts.

What does the HUB thread standard mean here? HUB is a 1.375×24 TPI thread interface; this mount is compatible with HUB-threaded suppressors from B&T and other makers on the market today.

How does this mount attach to the suppressor? It threads directly into the base of the suppressor tube and is tightened with a spanner wrench, with the option to add Rocksett or another thread locker for a more permanent installation.
