HM Defense AR-15 Bolt Carrier Group - Black Nitride
The HMB Bolt corrects a natural weak point in existing Mil-Spec M16, AR-10 & AR-15 bolts where the cam pinhole passes through the bolt. Under extensive use, including combat stress, a standard Mil-Spec bolt can fail at the cam pinhole location. The HMB Bolt by HM Defense eliminates the pass-through cam pin hole and replaces it with a cam pin socket and tapered cam pin design. This new patent-pending design eliminates the natural weak point of Mil-Spec bolts by significantly increasing the amount of metal (and strength) at the cam pin location. The result ? No more broken bolts! Additionally, the HMB Bolt reduces contact between the cam pin and the firing pin, enabling smoother operation of the firing pin, bolt lugs, and aft gas rings. The new cam pin socket also retains lubrication for extended operations.
