AR-15 7.62x39 | 5.45x39 Enhanced Firing Pin

A: We don't recommend it as you can pierce 5.56 primers. If you do decide to use the enhanced firing pin in your 5.56 we highly recommend checking for any pierce primers when using new ammo. If you are piercing primers install a standard firing pin for that caliber. Piercing primers will erode the tip of the firing pin if regularly piercing primers.

A: If the CMMG MK47 Resolute utilizes a standard AR-15 firing pin then yes the Enhanced Firing Pin will work.

A: Enhanced Firing Pins Are Engineered to Maintain Mil-Spec Characteristic Where the Firing Pin Interfaces Inside the Bolt and Still Allow Greater Protrusion Into the Primer

A: We have been manufacturing our own firing pins for around 12 yrs. We did the specs/drawings/machining/testing. We do not buy from other sources.

A: For deep set primers we recommend Part Number: 221214
While we did test on other ammunition and didn't experience pierce primers we always state while using new ammunition with this part number check the first few primers for pierce primers.

A: Enhanced firing pin is for the harder primers in the x39 calibers it allows for further protrusion. The Enhanced Plus firing pin allows for even further protrusion for those that have lot's of ammunition like we have seen in Tula that have deep set primers.

A: If you are having trouble with light strikes with an enhanced firing pin we ask that you contact us and ask for Charles so he can troubleshoot with you. There are other things outside of having an enhanced firing pin that can cause light strikes. You can reach out to us at: 386-410-5162

A: Yes it will.

For technical support call Thursday or Friday and ask for Charles: 386-410-5162. There could be a few things going on to cause light strikes.
