I'm in with a disconnect\hammer hook issue because if the rifle cycles the BCG and chambers a fresh round then the level of filth isn't keeping the hammer from being fully retracted. Something is keeping it from staying back. Check the trigger and hammer pins as well. Any side to side movement of the hammer or disconnect can keep the parts from mating up correctly.

Edited for spelling.

I had the same thing happen to my Anderson AR. There was a burr somewhere in the hammer/disconnector and when I couldn't find it I replaced the whole assembly with a LPK I had lying around; that solved the issue.

OP, how did it go? Get it sorted out?

I did the upper lube, and took a good look at the lower parts as well, and had an AR smith take a casual look at it. He found nothing out or sorts. Have yet to function test at the range, though. I will report when I get the time to do so.

Thanks everyone for your participation in this thread.
