    Put about 100 rounds threw a brand new davidson defense 223 wylde upper, had zero problems! Not 1 failure to feed,ejection issue, or light primer strike. Couldn't ask for better, or a better price!

    Solid Product

    I was able to buy this at a great price (as always) from e-arms and I am highly impressed with the manufacturing quality. It matches the Odin Works nitride BCG I paid almost double for! The staking on the gas key isn't as deep as I'd like, but it is adequate. Everything looks to be very securely attached, nothing loose. Every surface is sheeny, no tool or machining marks are evident. From the looks of it, I don't think the gas key is chrome lined, but I wonder if that's necessary with the nitride treatment. The bolt looks incredible, and I think this will only be even better with time and shooting.

    Great product

    Posted by Ryan on Jan 15th 2018

    Forty rounds in and no issues. Staking on the gas let are nice and deep, so no short cuts taken. Came lubed so it was as simple as sliding it in. Fast shipping. Overall great product. Highly recommended.
