Fired probably 120 rounds just fine have a full auto bolt and 5.8oz buffer but now it’s just firing semi auto not sure what wrong looks like everything is still in good shape. What should I look for? Or test. It’s combat arms made safety

Anyone know where any oil vein locations are near the highlands? i cant find a single one and all the videos i see on youtube dont show anything close at all.
