M16 Enhanced Bolt Carrier and Key with Buffer Technology

Black Rifle Arms^® M16/AR15 Enhanced 7.62x39 Bolt Carrier Group Patented Buffer Technology

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 the transition from upper to lower receivers, but it also buffers the impact between carrier and buffer. Comes with standard bolt carrier polymer buffer.

BOLT CARRIER:

• Bolt Carrier with Key Weight: 8.6 oz.
• Bolt Carrier Material, 8620
• Key Material, 4130
• Bolt Carrier Nickel Boron Coating
• Standard Size 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

1. AR-15 bolt carriers are not compatible with AR47 or any rifle that takes AK Magazines.
2. Bolt Carrier due to the polymer buffer is not compatible with most folding stocks.
• It is compatible with Shield Arms Folding Lowers.
3. JP Silent Capture Spring is not compatible with our bolt carriers. In order to use JP Silent Capture Spring, the end-user would need to make modifications to the carrier's integrated buffer.
4. Armaspec Stealth Recoil Spring is not compatible with our bolt carriers and bolt carrier polymer buffer can not be modified to work.
5. 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 manufacturer's recommendations before use on NiB/EXO coated products.
6. 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 9 years with over 20,000 rounds without needing to replace the polymer buffer; however, if one damages the polymer buffer it is easily replaced.
