KE Arms M16 Chrome Complete Bolt Carrier Group with HMB Bolt
Semi-Auto/ Full Auto M16 Complete bolt carrier group made by Young Manufacturing Inc. using MILSPEC quality steel on KE Arms in-house CNC machines. All carriers are then heat-treated, hard-chromed and each carrier is chrome-lined in the bolt throat.
- Standard MIL-SPEC carrier with additional care taken during machining process
- Sharp edges and rough finishes eliminated. Will NOT shred fingers and operates smoothly
- Hard chromed after heat treatment
- Made of same steel and using same processes as KE Arms National Match but to standard MILSPEC design
- The HMB Bolt by HM Defense eliminates the pass through cam pin hole and replaces it with a cam pin socket and radiused cam pin design. The 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 result- NO MORE BROKEN BOLTS! The HMB Bolt also reduces contact between cam pin and firing pin, enabling smoother operation of firing pin, bolt lugs and aft gas rings. The new cam pin socket also retains lubrication for extended operations.
- Also includes KE Arms recoil lug supported gas key
