Colonel Mustard muzzle device. A well-engineered update on the classic 'bird cage' - this model is beautifully detailed with multiple slots running from 7 o'clock round to 5 o'clock, leaving the lower slotless to prevent dirt being kicked up when used prone. Screws onto standard AR-15 / M4 ½" x 28 threaded barrels (with .223 / 5.56 bore). Includes crush washer and jam nut. CMMB51556.
