Q: what is the difference between 14081113 & 14081115 ?
Thanks in advance
A: Nothing, they are the exact same enhanced firing pin; however, due to SEO and searches for our customers doing specific 5.45x39 enhanced firing pin search or specific search for 7.62x39 enhanced firing pins we decided when the 5.45x39 caliber was much more popular to keep them separated for better search results for our customers.
Q: Is this for 556 cal. ???
A: No this is an enhanced firing (allows for further protrusion) for the 5.45x39 caliber. For 5.56/223 you need a Standard AR-15 Firing Pin. You can find the standard firing pin here: https://blackriflearms.com/AR-15-Firing-Pin-_p_203.html
Q: Will this work for. .223/5.56 BCG? Light primer strikes seems to be happening on non foreign reputable ammunition. And the extended firing pin was suggested to me by a guy who shot 7.62. But you have a 7.62 extended firing pin specifically for that caliber so that is why I’m asking for this one. Thanks
A: Both the 7.62x39 and 5.45x39 enhanced firing pin are the same pin that allows for further protrusion to ignite hard primers. On occasion a customer who is having light primer strikes with .223/5.56 ammunition due to hard primers our customers have had success with an enhanced firing pin. We do recommend if you are going to us an enhanced firing pin for this particular ammunition you are not having pierced primers. If you are you should stop and replace with standard firing pin. Piercing primers will erode the firing pin tip.
Q: What is the over all length of this firing pin??
A: 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: Will this firing pin work for light strikes on 300 blackout?
A: No we would not recommend this enhanced firing pin as it could cause pierce primers. Can you give us a call at 386.428-7960, if your having an issues with light strikes something else is going on and even though this is not our build we would like to help you diagnosis your issue and get you back to shooting. It's Thanksgiving, but we are around for a little while if you would like to give Charles a call. HAPPY THANKSGIVING!
