Trying to figure out how to solve the non fires with my 5.45 AR build.

I replaced the hammer spring with one of those wolf extra power ones, this helped but not completely.

I am using standard Wolf steel cased 5.45 ammo. Probably 1 out of every 4 rounds will not fire. All other parts are just standard AR parts, not sure what else I need to do in order to solve this. Hammer spring is installed correctly.

awesom... funny I thought about longer firing pins last night and then totally forgot about it by the morning.

I don't wana sound pompous but....

The ar15 was designed for soft primers of American 5.56

Even with the Wolff extra power spring that's really pushing it.

The 5.45 is for glorious Soviet hammer smack from crude Tula spring comrade'
