Q: I have a AR 15 in 7.62x39, I have bear creek enhanced firing pin, It works great, but I do still have some light primer strikes mainly on the Russian ammo. My question is I am looking for a lighter trigger pull but with the extra punch the 7.62 needs to set off the primers. Any suggestions that would help?

Q: What is the diameter of the spring wire. I am running a Wolff extra power spring in a PKM that has been converted to semiauto using a AR style trigger and a custom hammer. I can set off regular reloads but have to double strike Wolf steel case ammo. I need a heavier spring than the Wolff spring which uses a spring wire diameter of .050"

Without knowing if hammer spring is installed correctly or what fire control group you are using it's hard to say. If hammer spring is installed correctly and using a fire control group friendly to this caliber and you are using Tula then that could be your issue. If using Tula you might need the enhanced plus firing pin we designed for this particular ammo to allow for even further protrusion since we notice many are still having light strikes with this ammunition: https://www.blackriflearms.com/AR-15-762x39-545x39-Enhanced-PLUS-Firing-Pin-for-Deep-Set-Primers_p_883.html

Accepted Answer

Our enhanced power hammer spring was designed to provide approximately 1 lb more energy than the mil-spec spring and that in conjunction with our enhanced or enhanced plus firing pin has worked successfully for the harder primers associated with 7.62x39 and 5.45x39 ammunition. We designed our own as we didn't like the feel of the trigger pull of the other manufacturers' spring and we designed them with full auto in mind. We will send you bulk pricing in an email.

Accepted Answer

Our hammer spring is not going to provide any more strength than the Wolf Hammer Spring. Can you send a picture of your hammer spring in your lower installed so we can take a look to see if we see anything out of ordinary to help you. You can use our Contact Us page to send us an email with a picture attached.
