IWI US IWSQDMB24 LH QD Muzzle Brake 5/8-24 Quick Disconnect

The IWI US IWSQDMB24 is a left-hand quick-disconnect (LH QD) muzzle brake purpose-built to mate with the IWI IWS Series of QD-mount suppressors. Cut with a 5/8x24 thread pitch - the standard fitment for 7.62mm / .30 caliber host barrels - this muzzle device gives shooters a fast, repeatable, tool-free transition between suppressed and unsuppressed fire.

The left-hand thread orientation at the QD locking collar is set opposite of firing torque, so the attached suppressor stays secured during recoil pulses and is removed cleanly by hand when desired. When running unsuppressed, the brake helps reduce felt recoil and manage muzzle rise for faster follow-up shots.

Measuring roughly 2.3 inches in overall length, the IWSQDMB24 is a natural fit on AR-10-pattern rifles and any 7.62mm / .30 caliber threaded barrel hosting a suppressor from the IWI IWS QD family. It is the factory-matched QD interface for IWI IWS suppressors, designed and built by IWI US.
