The Gemtech 3-lug adapter threads onto standard 1/2-28 barrels and adds the HK-style tri-lug interface, giving pistol-caliber carbines and 9mm hosts the fast quarter-turn suppressor mounting the MP5 made famous. Tri-lug remains the gold standard for pistol-caliber quick attach — fast on, fast off, and repeatable — and Gemtech has been building suppressors and mounts longer than almost anyone in the industry. A simple, well-machined upgrade that makes swapping a 9mm can between hosts effortless.
