AR22 Service Life?

Has anyone had issues with their AR22? I have about 10k rounds through mine and I'm now getting light strikes and failure to fires. I recently ordered a bolt rebuild kit from CMMG so hopefully that will help resolve the issues. Wasn't sure what kind of life to expect out of these components.

I don't have anywhere near that many rounds through mine. However this is good to know. Let us know if this fixes the issue.

Good Luck!

At 10k it's time to replace your hammer spring, and the recoil springs for the bolt.

If the recoil springs are weak you'll have issues with light strikes from the bolt bouncing slightly out of battery or not going fully into battery when the bolt is fouled.

If the hammer spring is worn light strikes will happen. Contest it remove and lay it on the table. It should lay flat.

Thanks Chad! I pulled the bcg apart and have everything in the ultrasonic. I think I found my problem. 10K rounds of suppressed 22LR will gunk things up pretty good. I'm going to clean it and take measurement and see if it's still the same length but the face of the firing pin seems worn upon initial inspection.

That will do it. Check the hammer spring too.
