The Breek Arms BRK4300 Breek LOK 3QD is a quick-detach suppressor mount hub designed for shooters who need reliable, repeatable suppressor attachment on precision rifles. This titanium quick-attach system fits barrels with 1.375" × 24 TPI threads and uses a tri-lug engagement interface to lock your suppressor in place with minimal additional length. Whether you're running a tactical rifle, a hunting build, or a precision rifle at the range, the Breek LOK 3QD gives you the speed and security of a true quick-detach system without the weight penalty of heavier alternatives.
Built from aerospace-grade titanium with a DLC black finish, the Breek LOK 3QD hub weighs just 2.3 ounces—a significant weight advantage that keeps your rifle nimble and your handling sharp. The hub's dual engagement points—a tapered seating surface and tri-lug locking system—create a rock-solid mounting interface that returns your suppressor to the exact same zero position every time you attach it. That repeatability is crucial if you're running a can on a dedicated barrel; no more point-of-impact shifts, no more guesswork between range sessions or field work.
The minimalist profile adds just 1.15 inches to suppressor length, preserving your rifle's maneuverability while delivering the practical speed of quick-detach convenience. The Titanium DLC black finish resists corrosion and wear, holding up to repeated attachment cycles and adverse weather. This is a mount built for operators who demand precision, speed, and dependability—whether you're prepping for a long-range hunting trip, maintaining your barrel between matches, or simply want the flexibility to swap suppressors or run unsuppressed without tools.
