FailZero Pin


After 500 rounds fouling just wipes away. No misfires or shallow primer strikes. What else can you say about a firing pin?

F Z firing pin


Another backup component, haven't used it but wanted a spare. It is what it is! PA always delivers on time! Great to do business with them.

NiB, can't go wrong for the price.


Definitely less carbon after same number of rounds.

Excellent customer service and awesome communication. Will continue to do business.

Great so far


Great price and fast shipping.

Best price on the Internet


I bought this because my Colt LE6920 factory bolt failed to eject a couple of times. This Fail Zero is worth the money. It's been 100% after about 800 rounds.

looks to be above mil spec


I'm only giving four stars because I haven't used the firing pin in actual firing. However, compared side by side with a S&W unit the Exo pin looks tougher. The quality seems to be on par with higher end equipment.

Great product


I'm very happy with this firing pin so far. Only shot 400 rounds so far but the pin still looks new.

firing pin high quality


keeping an extra firing pin and and extra lower parts kit is a must,and stored in hand grip and stock so it is right with the rifle at all times.Be prepaired.thanks Primary Arms will be doing more business with your 5 star company.

Good Firing Pin


The two Fail Zero EXO firing pins I ordered arrived on time and were exactly as described. I replaced the regular firing pins in two ARs and put the originals away as spares. So far, I have had no issues with the Fail Zero firing pins in either rifle. I was pleased with my order from Primary Arms and would not hesitate to order from them again.
