Built in-house on our automated Nakamura CNC machines with the most up-to-date materials and technical specs, these are among the finest AR bolt carrier assemblies available on the market. Like all Wilson Combat accessories under our “Bullet Proof®” service policy, if the product ever fails we will repair or replace it at no cost to you-no strings attached.

The Bullet Proof® bolts are finely machined from 9310 AQ aerospace quality tool steel bar stock, heat-treated to Mil-Spec core hardness with a case hardened surface. 9310 AQ achieves high core strength and maximum toughness for this application. A snug fitting 302 stainless helical one-piece gas ring is used for optimal gas seal and extended service life.

The extractor is fully machined from 4140 bar stock, properly heat treated, stress relieved and phosphate coated for non-slip extraction. The extractor uses an extra power chrome silicon spring with inner buffer and “Crane” O-ring for positive extraction and long service life.

The bolt carrier is precision machined from 8620 tool steel billet and then precisely heat-treated to meet or exceed military specifications.

The gas key, a critical component for reliability is fully machined from 4140 steel, heat-treated, and installed with both high strength, heat resistant sealant, and 170,000PSI screws torqued to 55-58 inch pounds and staked so you never have to worry about the gas key coming loose and causing a malfunction.

These advances in manufacturing and materials have greatly enhanced the reliability, performance, and lifespan of the most critical part of your rifle.
