Put a 300 Blackout cartridge in it and pull the trigger, it will find the problem so you can fix it! All I need was a new upper, barrel, BCG, and lower. Thank God I wasn't hurt.

Seriously try swapping your upper with someone to see if the trouble goes away.

Lol someone finally has a good idea. Only took two pages worth of other crap.

I have a Bushmaster .223 upper and lower I could swap in. Struggling to get freed up to get to the range. Too much work travel.......

Thank you for your help and insightful suggestions.
