The Kuna Tri-Lug combines roller-delayed performance with a suppressor-mounting interface rooted in iconic HK heritage. Designed for pistol-caliber platforms, its integrated tri-lug system allows compatible suppressors to be attached or removed quickly and securely without tools. The simple push-and-twist connection makes switching between suppressed and unsuppressed configurations quick and intuitive. Combined with the Kuna’s monolithic aluminum upper, fully ambidextrous controls, and compact, highly maneuverable design, the Kuna Tri-Lug models provide a streamlined suppressor-mounting solution.
