Our Wilson Combat Bullet Proof® AR-15 Bolt Carrier Assembly is meticulously crafted using high-end Nakamura CNC machines and the most advanced materials available. As part of our "Bullet Proof®" service policy, if for some reason any components fail to meet your expectations, Wilson will repair or replace them free of charge - no questions asked! These bolts have been carefully machined from 9310 AQ aerospace quality tool steel bar stock and then hardened in line with Mil-Spec core hardness standards while boasting a case-hardened surface. These are certainly among the best bolt carrier assemblies you can find on today’s market!

The 9310 AQ is designed for maximum toughness and durability. It comes fitted with a 302 stainless helical one-piece gas ring to ensure optimal gas sealing, making it perfect for extended service life. For added assurance of non-slip extraction, the extractor itself is machined from 4140 bar stock that has undergone proper heat treatment and stress relief before being phosphate coated. Moreover, an extra power chrome silicon spring with inner buffer as well as "Crane" O-ring provide positive extraction while also guaranteeing long term useability. Meticulously machined from 8620 tool steel billet and heat-treated with exacting precision, the bolt carrier surpasses all military specifications.

The gas key, a crucial element for dependability and longevity, is manufactured from sturdy 4140 steel. It is then heat-treated and installed with both durable sealants capable of resisting high temperatures as well as 170,000PSI screws that have been firmly torqued to 55-58 inch pounds. Furthermore, the screws are securely staked in order to ensure your rifle remains malfunction free due to an unsecured gas key coming undone. Thanks to these advances in manufacturing techniques and materials used there have been tremendous improvements when it comes to the reliability, performance, and lifespan of this essential part of every rifle!

  • 9310 AQ Bolt, properly heat-treated, stress relieved and MPI inspected with a stainless, helical gas ring
  • 8620 machined “full auto” style bolt carrier
  • Drop-in fit for any quality 5.56 case head based AR rifle (.204 Ruger, .223/5.56 NATO, 300 HAM'R, .300 Blackout, 7.62X40 WT or .350 Legend)
  • 17-4 stainless steel corrosion-resistant firing pin
  • Carrier, bolt, gas key, gas key screws, and cam pin are Black Nitride finished for reduced friction, increased durability, and ease of cleaning
  • 11.2 oz.

NOTE: The only difference between “semi-auto” and “full-auto” carriers are the carrier weight and external profile. The “full-auto” carrier is slightly heavier to provide more mass and lower cyclic rate that can benefit carbine length and shorter gas systems, short barreled/suppressed rifles and machine guns. The “semi-auto” carrier is slightly lighter to provide the least amount of recoil impulse for rifle length gas systems and it's design makes reinstalling the firing pin easier after cleaning.
