  1. Isaac Holyk

    Super nice!!! This BCG looks great and is very high quality. Properly staked and proper O ring. The natural lube from the nickel boron is very noticeable when you touch it. Much higher quality than standard BCG’s and seems to have a smoother action and charge. For $99, you can’t go wrong. Besides it is most likely and Aero Precision BCG because only a few companies make them.

    If you have a mil-spec BCG then you should definitely consider getting this, but something I wish I had done before buying this was I should have gotten the polished version for a few dollars more other than that this BCG has fired well and has had no malfunctions. It came internally lubed however I did lube the outside of it and any contact parts. Like any nickel boron Bolt Carrier Group it’s easy to clean.

    I picked one of these nickel boron bcg’s up for my 300 blackout pistol on sale for $70. It’s run flawlessly, and it’s very well machined. I will definitely be picking up a couple more for upcoming builds. I highly recommend these to anyone in need of a good bcg.
