Smith Enterprise now produces the Good Iron Muzzle Brake for the AR-15 platform. The brake is machined from 8620 steel, then put through a salt bath nitride coating process to make it nearly impervious to corrosion and wear. In addition, it undergoes a rigorous heat-treating process to stave off gas erosion.

An advanced arrangement of 14 gas ports will stabilize your rifle by projecting gases upward and out. This has the effect of cancelling out recoil and muzzle climb, allowing you to take quicker follow-up shots and avoid the discomfort of recoil. The bottom of the brake is intentionally left closed to prevent it from creating a conspicuous dust cloud when firing in the prone position. The rounded profile prevents the brake from snagging on gear, clothing, or other objects.

Quality Muzzle Control for the M4/M16/AR15 Platform

The 5.56 Good Iron Muzzle Brake is the Smith Enterprise answer for quality muzzle control for AR type rifles with ½ x 28 threaded barrels. The hardened 8620 steel features a corrosion resistant salt bath nitride finish that’s ready for the challenges of your operating environment. Smith includes the jam nut required for installation so you can get off the bench and get on with life with less hassle. The Good Iron Design features port distribution that’s perfect to control muzzle rise and kickback without dust-printing issues. All you have to do is choose your target and shoot. Reduced motion makes it easy to stay on one target or acquire your next without missing a beat.
