This Aero Precision 5.56 Complete BCG is one of the highest-rated and most popular Bolt Carrier Group BCG. That’s because changing out the BCG is one of the easiest AR15 modifications you could make, and Aero Precision is synonymous with quality. These Bolt Carrier Groups are constructed from 8620 tool steel (and 9310 steel for the bolt), shot peened, and magnetic particle inspected, so you can trust that they’re built to last. The Aero Precision AR15 5.56mm Bolt Carrier Group features military specifications (mil-spec), including the gas key and extractor spring. Also, in the carrier itself, Aero machined forward assist serrations. It’s also available in various high-end finishes like phosphate, nitride, and nickel boron, but no matter the finish, it gets polished, so, in the end,, you have an easier time cleaning dirt and carbon buildup. If you plan on modifying your AR rifle, grab the Aero Precision 5.56 Complete Bolt Carrier Group BCG today!

Rather than purchasing a complete ready to shoot AR15, wanted to pick & choose all my parts and features for my first dream build. I’m really pleased with my choice to use the Aero Precision BCG. Perfect finish and finish, great price & customer service was fast. I highly recommend Optics Planet!

Quality product. Cleans easily. I've shot 500 rounds so far smooth action and no misfires. Arrived very quickly after ordering and I will be buying another one for my next AR build. I have and will recommend this product to my friends.

these aero precision bcg are good quality units, have used one for at least a year no issues to date, i prefer the black version myself. my brother has the other version and both of them function fine dirty or clean in a 16 and a 20 inch upper, no fails at all in hot or cold weather.

Great .300 Blackout Carrier Bolt from Aero Precision, never an issue from any of their other Bolts I've purchased in the past. Smooth, impeccable finish, looking forward to many years of trouble free enjoyment. Plan on purchasing one for my next Truck Gun build as well.
