Yankee Hill Machine Company Low Profile Muzzle Brake Features The Yankee Hill Machine Low Profile Muzzle Brake is machined from steel and finished with Melonite QPQ a nitriding process that improves surface hardness and corrosion resistance compared to standard coatings. At just 2.225 inches long 0.735 inches in diameter and 2 ounces in weight this brake keeps the muzzle profile compact and unobtrusive compared to larger more aggressive designs. The 1/2x28 thread pitch matches the standard pattern used on most 5.56mm and .223 caliber AR-15 barrels making installation straightforward on a wide range of rifles. A low profile crush washer is included ensuring the brake can be properly timed and torqued into position during installation. One of the standout design details of this brake is that it allows gas blocks with a 0.75 inch inside diameter to be installed or removed without needing to take the muzzle device off first which simplifies maintenance and gunsmithing work down the line. This thoughtful design consideration saves shooters time and hassle when performing routine maintenance or swapping components on their rifle. Yankee Hill Machine has built a reputation for producing durable functional muzzle devices that balance recoil control with a low visual profile. This brake is a solid option for AR-15 owners who want effective recoil reduction without a bulky or attention-grabbing muzzle device.
