Traded for a little used AR-15 a while back, just now had time to shoot it. Performs great in every way I expected except the trigger pivot roll pin started backing out on one side after 30-40 rounds. It is lightly snug, but a little looser than normal to stay in place.
It has an Anderson AM-15 lower, unknown trigger. The roll pin seems to be .154 inch the best I can measure it on both ends without disassembly.
Is this the normal size for the trigger roll pin or do I have one smaller than expected?
If this pin is the right size, do I need to clean the oil off and apply something like Vibra-Tite, or try to expand each side a little with a punch? Kinda hate to try the punch thing if I do not have to.
Thanks.
