After recently disassembling my m4 i cant get my front receiver pin to go all the way through. I tried to hammer it in with a rubber hammer but that didn't work either. Is there anyone who got some tip or trick to get it to work?
I was referring to the fact that you have drilled the hole bigger, which over time may allow flex in use, which in turn could cause the hole size to increase....not a good outcome.
my reference, an old slang term, can be explained here:
Thing is, they're supposed to be a close fit. If they don't line up without modification it means that something else is out of line elsewhere. You've addressed the symptom but not the cause so you may find you have more issues down the road.
