does M1 need a breakin?

[zippo251]

I have a AOM130. Bought it new on the first outing it seemed to have feeding issues. No difference with different mags. About 100 rounds but never a complete mag. Do I need to figure on a break in period? And if so how long. Gun is well cleaned.

My AOM130 had an issue of not fully seating the bolt after grabbing the next round to fire. a little oil on the parts that started to show signs of metal through the parkerizing and I have not had any problems since. I just keep lightly lubing these rubbing points and all works well. I don't think there is a break in period. Some of the reviews like the one from NRA just put 500 rounds through it new.
