The M4SD suppressor is back- providing the original project goals- an affordable, sound suppressor with support for compatible A2 compensators. Taking the lessons learned from the M4SD II flagship development program, we simplified and produced a more economical suppressor and are passing on the savings to the customer. The M4SD retains the welded, 17-4 billet construction and is as durable as the flagship suppressor. Full auto rated, equipped with a user friendly snap on interface, backed by an extensive muzzle device family- the M4SD suppressor is a great suppressor for the entry level NFA enthusiast desiring a QD interface.

The M4SD mounting system does not suffer from the wear prone issues of ratcheting systems common to the marketplace.
Our SDQD mounting system was designed to provide trouble free use.

Rated on Following barrel lengths : No barrel restrictions! While longer barrels promote longer service life, this suppressor has no length restrictions!
