Please note: ALL 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 flaws.
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.
- Weight of BCG: 10.76 oz.

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.
