        I have about 8 failzero bcgs. I have had them for years and because of how well they had worked I just kept buying them. Well I have 3 that are brand new, never put in a gun that just sat in my drawer with extra parts that started to rust. I called repeatedly and left messages with failzero customer service as well as email them with pictures. Never once did I get a reply. I tried to clean them with the hope that maybe if I cleaned and oil then then maybe everything would be ok and the coating bubbled up and came off. Stay away! I Will NEVER BUY FAILZERO AGAIN! At least a warranty denial would be better than no answer at all.

        No doubt this looks good. Only time will tell if it  stays pretty. Cleaning it seems harder, you can see every little gunk unlike the black factory BCG. Also not as easy to clean as you would think, carbon seems to stick to it pretty good and I leave a thin CLP coating on it too.

        Top quality bolt carrier group. It is my preferred bcg by far. Great quality for the price point.

        I bought these because they were on sale and I had always had good luck with Fail Zero products.   Not this time both were deadright out of the package.   I took them in the house disassembled and oiled them tried again and one shot again.  I took them outside and had my wife video it.  I have had bcg that worked in other guns but these don't run in my Daniel Defence or my other Proof Research barreled upper.

        This bolt carrier group is very slick. I don't know how long the nickel boron finish will last yet since I've only fired about 300 rounds with it, but it operates flawlessly and is very easy to clean. If the finish holds up this will be my go to bcg for future builds.

        Ive put thousands of supressed rounds in everything from 198 silverback 300 to 458 socom out of these carriers and never had a problem. They always run dry no clp only clean em when something starts to mess up. For the money how can anybody complain about these bcgs unless they get a rare factory lemon

        It initially seemed nice but upon closer inspection it has a major flaw and a minor flaw. Major - The right sides of both screws were not properly staked. The indentations weren't even touching the screw. Minor - it has a good number of tool marks on it, though they are cosmetic and not in places where it contacts the rifle.

        I have one of these in my AR-15. I used a BCM extractor upgrade kit, and a milspec hammer spring (not sure if nessessary), but my AR-15 eats steel like it was brass. I shoot brass and Wolf steel loads with no problems/ ftf. These things are solid. They are also very easy to clean. Keep in mind that nickel does have a tendency to stain after a while. Diamond metal polish will remove the staining, but i dont think its worth it personally. It still maintains the same lubricity and function, stained or not.

        This is a good bcg I have used it and have had no issues. It looks great and funtion great my only negative is the bolt itself is a little harder to clean the carbon off of. I read reviews saying it was the super easy to clean. the rest of it wipes clean with just a rag over all  the bcg is worth buying

        The name says it all “FAIL ZERO” and it’s true to form... The Fail Zero BCG is by far my favorite go to for any AR build... The finish is very durable and very slick which saves on wear and tear with your upper receiver... The price is very competitive for such a high end BCG... i’m tried out many different BCG’s and I always find myself going back to FAIL ZERO...    
        
            
                                                
                        Pros:

                                                                    - nothing so far
 
                                                                    - None so far !
