HMB Bolt Carrier Group - Black Nitride (Made in USA)
Click Image for Gallery
HMB Bolt by HM Defense is made in the U.S.A. and the HMB is 100% compatible with Mil-Spec M16 & AR-15 BCGs and can be installed as a drop-in bolt replacement in any existing M16 or AR-15 rifle. The HMB bolt eliminates the pass through cam pin hole and replaces it with a cam pin socket and tapered cam pin design. This new patented 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 ultra-hard and corrosion-resistant Black Nitride ensures this BCG's continued reliability and precision. Additional benefits of the HMB design include the elimination of the cam pin hole staking, reduction in potential cam & firing pin contact and a smoother operation of the BCG.
