Bolt Carriers are hand polished and packaged in-house as an order is placed so we can inspect each bolt carrier and ensure there are no flaw

Black Rifle Arms™ M16/AR15 5.56x45 Enhanced Bolt Carrier Group featuring our Patented Buffer Technology  

Due to our stringent quality control, we set out to improve upon existing bolt carriers. The enhanced carrier's integrated buffer helps not only to eliminate metal on metal contact during transition from upper to lower receivers, it also buffers the impact between carrier and buffer. 

  • All carriers are hard turned after heat treatment to ensure proper and unaltered tolerances. 
  • Our NiB EXO FailZero coating gets a final polish after application to ensure a smoother finish. 
  • Bolt Carrier Group is DROP IN READY. 
  • BCG Weigt: 10.76 oz.

Bolt Carrier Buffer System

  • Bolt Carrier Material, 8620
  • Key Material: 4130
  • Bolt Carrier FailZero EXO Nickel Boron Coating
  • AR-15 Firing Pin 
  • Bolt Assembly, 9310, Melonite QPQ
  • Cam Pin, Melonite QPQ
  • Firing Pin Retaining Pin 
  • Integrated Polymer Buffer:
    • Eliminates metal on metal contact
    • Eliminates contact between the hardened steel carrier, aluminum receiver extension and buffer
    • Eliminates hardened steel carrier as it transitions between upper and lower receivers
    • Self-lubricating, shock absorbing, and has seven times the abrasion resistance of carbon steel
    • Reduction in felt recoil and vibration

Please Note: JP Silent Capture Spring is not compatible with our carriers buffers. In order to use JP Silent Capture Spring end user would need to make modifications to the carrier's integrated buffer. 

Our Select Fire Customers have stated carrier bounce has been eliminated due to the polymer base buffer. We have run select fire and have not experienced carrier bounce since the introduction of the integrated polymer base buffer. Patented buffer technology has been in use for 7 years with over 15,000 rounds without needing to replace the polymer buffer; however, if one damages the polymer buffer it is easily replaced.

Important Note: Some off-the-shelf rifle cleaning solutions such as Hoppe’s #9 can react negatively with NiB finishes. Since our carriers have nickel based coating these should not be used on NiB/EXO coated products. Always refer to the manufacturers recommendations before use on NiB/EXO coated products.

Singularly the best BCG I've ever run & I've run them all. I ran this at the range today using everything from premium U.S. made ammo to rotgut combloc steel cased ammo almost 50yrs old. Not one hiccup. I run this bolt with a CTS 'AKTIVE' ANTI-TILT Recoil Buffer in and out of a Strike Industries Mil-Spec/Com-Spec Hybrid 7 position tube, all married to a Ruger SR556 lower. I cannot believe how smooth and silent this bolt works with that buffer; no spring rattle, no buffer rattle or wobble, no scraping of the tube walls - incredible BCG. I just learned of your company two weeks ago and I've already bought two - this one in 556 and one for the x39. I'll be back for more. Happy Holidays!

Bolt's performance
It is amazing, the feel of the rifle and how smooth it is. With the elimination of the carrier bolt tilt(Something I never really thought about) it's so simple yet it makes a world of difference. I would not get another type of BCG ever again. I want to get a complete upper after this.
