Q: I just installed the firing pin in my AR Olympic Arms bolt and noticed that there is a gap between the firing pin stop and the back end of the bolt. Is it safe to use like this?
A: Please do not use and contact Olympic Arms. When we dealt with them years ago they were shortening the tail end of their 7.62x39 bolts for use with standard firing pins. I'm concerned if they machine their bolts for standard firing in our enhanced firing pin may pierce primers.
Q: Is this enhanced pin a few thousandths longer?
A: Without getting too technical, we designed it with a couple of other features that allow the best performance where we saw some functionality issues with other designs. Overall length is irrelevant to the performance of our enhanced firing pin. We designed our enhanced firing pin with multiple dimensional changes beyond overall length.
Q: Can this be used on standard 308 ammo?
A: No, the 7.62x39 is for the AR-15 platform of rifles and is not designed for use with the larger platform such as the .308/AR-10/7.62x51.
Q: Will this pin work in a 5.56 ar?
A: We do not recommend an enhanced firing pin for the 5.56 caliber as the enhanced firing pin allows for further protrusion and can cause pierce primers. Please stick with standard firing pin for the 5.56 ammunition.
Q: I recently purchased 2k rounds of Golden Tiger .223 . I am getting light strikes. Will the Enhanced 7.62 x39 firing pin work in a .223 AR 15 bolt?
A: Our enhanced firing pin will work in any AR-15 mil-spec bolt; however, we highly recommend that you check for pierced primers if not using in n x39 caliber rifle.
Q: will your 7.62 x 39 enhanced firing pin work with an ARP 6.5 Grendel upper? I am having unreliable ignition with 6.5g Wolf ammo and a Jewel trigger?
A: The enhanced firing pin will fit any mil-spec AR-15 bolt assembly, so will it will work in a 6.5 Grendel, we do highly recommend that if you use an enhanced firing pin with your 6.5 Grendel that you watch for pierced primers as it does allow for further penetration.
Q: I bought a bulk amount of 223 Russian ammo that apparently have 5.45x39 hard primers in them. What do you recommend I use? The 545 or 762 enhanced firing pin? A.
A: The 5.45x39 and 7.62x39 enhanced firing pins are identical so either one will work with the hard primers.
Q: Will this firing pin fit on a Ruger mini 30?
A: No, this enhanced firing pin is designed for the AR-15 platform.
Q: Will this fit a MK47 Mutant 7.62x39?
A: If it uses a mil-spec firing pin then this pin should work fine.
Q: will this fit mgi bolt?
A: If MGI bolt will take an AR-15 firing pin then this enhanced firing pin should not have any compatibility issues.
