(3) i paid $500 for this gun from the original owner because he said it was broken because it chainfired, i can verify that it did, and it needs a good thourough cleaning
If this is truly the case, I would remove that fire control group from that gun IMMEDIATELY and dispose of it. Replacement parts are cheap, albeit in high demand lately.
Just scrub it out like you did in the Corp...
