Rugged Suppressors 3-Lug Mount

The Rugged Suppressors RU3 Universal 3-Lug Mount enables HUB/universally threaded suppressors to attach to HK-spec 9mm 3-lug firearms and subguns. This adapter provides a streamlined mounting solution for pistol caliber carbines and other 9mm platforms.

Built in a bixler-style design, the RU3 utilizes a taper lock mechanism rather than spring tension. This engineering approach delivers a tighter, more concentric lockup for improved reliability and repeatability during repeated attach/detach cycles.

The mount features 1/2x28 barrel threads and 1.375x24 suppressor threads, accommodating suppressors like the Alaskan360, Sub9, and other HUB-compatible models.
