- Complete Nickel Boron Assembly

A*B Arms is built stronger because sometimes, lives are on the line. Their products stand up to the rigors of combat, police and private security operations, where failure is not an option.

The A*B Pro 5.56/.223/.300/.350 Bolt Carrier Group is a MIL-SPEC drop-in ready component for the AR-15/M4 platform. The nickel boron finish offers dry lubrication for treated parts. The carrier, bolt, and cam pin require virtually no lube during use. The phosphate coated extractor has a surface finish providing superior extraction during firing.
