Yankee Hill 4401MB24 sRx QD Mini Muzzle Brake 9mm 5/8x24 Black Phosphate Steel

The Yankee Hill 4401MB24 is a compact quick-detach mini muzzle brake designed to mate with YHM sRx suppressor mounting adapters. Machined from steel with a black phosphate finish, this short-profile brake is built around the sRx system for fast, repeatable attachment and removal of compatible YHM sRx-series sound suppressors.

Featuring a 5/8x24 thread pattern, the 4401MB24 threads directly onto barrels chambered in 9mm and other host firearms with matching threads. At just 1.10" overall length, the mini profile adds minimal bulk to the host firearm while preserving the quick-detach functionality of the full-size sRx brake.

This is a current production Yankee Hill muzzle device in new condition, ready to install on a properly threaded barrel.
