BCG is solid very smooth, glides in the upper. The bolt already has a strong extractor spring and didn’t require an up grade kit with a stiffer spring like most do.

The BCG came packaged very well. The bolt is very smooth and the craftsmanship is better than any. The Nickel Boron Nitride is amazing and very easy to clean carbine buildup off of. The BCG runs great without issue. The FailZero has one of the best ejectors a AR bolt can have, the spring is very well made and holds the ejector tight. FailZero makes a great product and Optic Plant had an amazing price and fast shipping
