The Fail Zero complete bolt carrier is the BCG that you want to put in your rifle. The Fail Zero BCG's are assembled and ready to drop into your mil-spec upper receiver. The thing that sets fail zero apart from other manufacturers is that all the critical parts are coated with EXO Nickel Boron technology which provides permanent dry lubricity. You will also notice that the fail zero will be extremely durable and will have an increase in wear and corrosion resistance. The Nickel boron coating will reduce friction and improve the overall performance of your firearm.

What is a hammer in a bolt carrier group ?
Answer:
The bolt carrier group does not have a hammer and one is not typically included with a BCG. This same manufacturer used to also sell the same BCG with a nickel boron coated hammer and since the manufacturer added a little 'no hammer' sticker on the packaging; the person writing the description added 'no hammer' to the description to avoid confusion when the customer receives the item. I apologize for any confusion this may have caused.
