Product Description

The Wilson Combat Bolt Carrier Assembly for 5.56 NATO is built by top domestic Mil-Spec contractors and is designed to deliver long-term reliability in AR-15 pattern rifles. The bolt is precision machined from Carpenter 158 steel, shot peened for increased strength, and includes a tool steel extractor and ejector with the proper extractor spring. Bolts are randomly batch HPT (High Pressure Tested) for added confidence. The 8620 steel carrier features a Parkerized exterior with an internally chrome-lined bore, plus a properly machined Mil-Spec gas key that is chrome lined, phosphated, and heat treated to GI specifications. The gas key is secured with Grade 8 fasteners and properly staked during final inspection for dependable gas system function.
