Experience optimal reliability and performance in your rifle when you choose the Wilson Combat Bolt Carrier Assembly for 5.56 NATO. This robust solution ensures rugged dependability, no matter the conditions. This bolt carrier assembly features a black nitride coating and is precision machined from aerospace-grade 9310 tool steel, making it incredibly tough. The hardened steel 8620 carrier also features forward assist cuts for added reliability. Additionally, the gas key is properly staked to ensure it won't fail at the most inopportune moment. This bolt carrier assembly is used in Wilson's fully-built rifles and will provide unbeatable performance and durability for any shooter who needs dependability they can trust.

  • Black nitride coating provides robust dependability 
  • Precision machined from aerospace-grade 9310 tool steel for toughness
  • Hardened steel 8620 carrier features forward assist cuts 
  • Properly staked gas key ensures reliable performance 
  • Machined ejector and extractor
  • Drop in fit for any quality 5.56 case head based AR rifle (.223/5.56 NATO, .300 Blackout, .204 Ruger,300 HAM’R, or 7.62X40 WT)
  • Used in Wilson's fully-built rifles for optimal performance and durability

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.

    shot-peened 6930 bolt, nitride coated carrier, bolt, cam pin, complete with firing pin, skillfully staked gas key. Arrived fast. Highly recommend Wilson Combat and all of their complete bolt carrier groups. The nitride finish is easy to clean. Also has a 1 piece gas ring design.

    Posted by Robert on May 26th 2020

    This BCG I own 4 of them. The Nitride coating is amazing in many ways. Very easy to clean and requires very little lube. Never had an issue with it.

    Simply The Best!

    Posted by Barry on Jan 14th 2020

    Over the course of 45 years I’ve used any number of bolt carriers from S&W, Bushmaster and at least two dozen others but none of them were even close to the quality of the Wilson Combat in Black nitride. After putting my first 500 rounds of 77 grain .223 using this bolt carrier it shows absolutely no signs of wear and cycles as smooth as silk. I bought one in Nickel Boron as well which I plan on using in another WC Upper but the carrier in Black nitride is just unbelievable. The coating and the way it’s applied is far better than the way WC used to make them. This bolt carrier was $160 and while it isn’t cheap you get what you pay for and I anticipate this should last at least 20 years, you read that right, 20 years! This thing cycles smooth as glass and as I said it shows zero signs of wear. Buy it, you won’t be sorry.

    Top Tier

    Posted by Ryan on Nov 23rd 2019

    This is the same quality as my Noveske black nitride BCG top tier quality you get what you pay for. Not even the same playing field as parts out of a $500 MSR
