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.

"Went over 600 rounds, suppressed, with steel case before the first cleaning and had one failure to feed. Most likely due to an undergassed round causing a short stroke, this was on round 20. No other failures and then it wiped clean ready for more abuse. If you tend to get rifles dirty, get this BCG."

"I used this BCG for a new build and it works great I have had no issues with it at all. It is easy to clean compared to my black mil spec BCG. I used it with a DPMS bull barrel and have been getting 1/2 moa no complaints."
