Liberty Precision Machine Liberty Bell Features The Liberty Precision Machine Liberty Bell muzzle brake is CNC machined from 17-4 PH stainless steel with all critical alignment features cut in a single setup ensuring consistent repeatable fitment. Heat treated to an H900 condition the brake offers a substantial improvement in recoil reduction over factory muzzle devices while keeping concussion to a minimum. A 360 degree port orientation means the brake performs consistently without requiring shims during installation saving the shooter time at the bench. Built around a .30 caliber bore with a 1/2x28 thread pitch the Liberty Bell threads onto a wide range of common .30 caliber rifles. Designed for direct compatibility with common .900 inch by 24 threads per inch silencer mounts including the Q Plan-B and Rearden MFG Atlas the Liberty Bell gives shooters an easy path toward adding a suppressor down the line. A 13/16 inch rear hex allows for quick tool-assisted installation and removal without damaging the finish. At just 1.70 inches long and 1.6 to 2.0 ounces the brake adds minimal length or weight to the host rifle. Finished in Black with a durable nitride coating the Liberty Precision Machine Liberty Bell is available for sale at GrabAGun.
