Thousands of rounds AR15 now giving light primer strikes

[EPS]

What kind of trigger is in it ? I put one of these cheap triggers in the gun I built for my sister it fired a few rounds and started light strikes so I bought a VELOCITY TRIGGER PROBLEM SOLVED

If you just have a mil spec try JP ENTERPRISE SPRING KIT I have a few different things from them and they are good

Are you running an OEM trigger group? Like already said better before me strip and clean the BCG. Examine the firing pin ends. Replace the hammer spring. Clean the barrel extension and lugs. Clean the chamber. Use military spec 5.56 ammo.

I haven't had a chance to mess with it between finishing my work bench in the garage, so I have a place to do this stuff again, and completing this P80 "Glock" frame.

I'll be sure to update here with what I've found. Most of the parts in it are super cheap from gun shows about 10 years ago, as in totally random. I haven't had a reason to even look at twice except light cleaning.

You guys bring up stuff I've since forgot and it's why I posted here! Thank you.

Don't neglect your chamber

That's why I love my piston model, DI are nasty chambers that requires a lot of cleaning.

If all what is said above fails to fix it check head spacing.
