The Yankee Hill Machine Low Profile Muzzle Brake (brand part number YHM25A) threads onto a 5.56mm/.223 AR-15 barrel at the standard 1/2-28 pitch and keeps a compact, low-profile footprint that clears most handguards without extra fitting. YHM machines the brake from steel and finishes it in Melonite QPQ for corrosion resistance, keeping total weight to just 2 ounces so it adds almost nothing to the muzzle end of the rifle. The low-profile body is specifically sized to allow gas blocks with up to a .75-inch inside diameter to be installed or removed without pulling the brake off first, a real time-saver during a barrel or gas block swap. It ships complete with a low-profile crush washer for a clean, properly timed install.
