Dirty Bird Industries Enhanced Bolt Carrier Group .223/5.56
The Dirty Bird Enhanced Bolt Carrier Group for .223/5.56 features a unique full-auto carrier design with practical improvements in two key areas:
- Strategically relocated load bearing surfaces reduce carrier tilt/can’t during recoil, thus increasing reliability and longevity.
- Additional wall thickness in the gas exhaust port area for added strength and rigidity.
The 9310 Bolt is machined to mil-spec dimensions and then the external surfaces including the lugs are CNC ground after the heat treating process to ensure a very precise fit. The bolts themselves feature the same Black Nitride finish as the carrier and are High Pressure (HP) Tested and Magnetic Partical Inspected (MPI) in accordance with Mil-STD-1816 specifications.

Dirty Bird Ind. Charging Forward
Solid product overall. Gas rings are clean and non pour outs under microscope. Gas keys need to be staked deeper. Overall a great value and well engineered. Step above Milspec
USSolid BCG
Great coating and design for a decent price. So far so good.
USDBI .223/5.56 Enhanced BCG
AR 15 Discounts is always helpful and never disappoints. BCG looks like a great product with nice staking. Have not shot yet but don't expect any issues.
USEnhanced bolt carrier
The extra tight fit in the upper seems smoother but definitely quieter ! When wreaking the bolt those ridges for the assist just don’t make that noise
USAwesome BCG
Ran flawlessly in my build. Not one hiccup and definitely great craftsmanship. Dirty Bird Industries has done good by me. Will definitely buy more of their products especially with AR15 Discounts prices.
