HB 5.56 Pro+ M16 Bolt Carrier Group Skeletonized, Nitrided
Beyond "MIL-SPEC" Hughes Ballistics delivers the best options available for our customers.
The Low Mass HB Pro+ Skeletonized BCG reduces mass in the carrier while delivering full functionality, a full 1.7 ozs below our Enhanced BCG at 9.3 ozs.
Other improvements include using 9310 tool steel for the bolt, nitriding the assembly to increase surface hardness, increase lubricity, and provide superior corrosion resistance compared to typical chrome and phosphate bolt carrier groups. All bolts are fully MPI tested to ensure the material is without defects.
