Norinco cq a 5.56
A bit off the subject, but useful info. After swapping out the internals and buffer tube of two NORINCO CQ A 5.56's into Aero Precision lowers I found all part were 100%, with the exception of the hammer and trigger pins. The hammer and trigger pins on the Norcs are about 2 or 3 thou larger than the standard American pins. Not much of a difference, but on a Aero lower I found the pins would not fit into the holes. The smaller American pins work fine on the hammer and trigger- no walking at all. Aeros are good standard config. lowers I expect most NORINCO CQ A 5.56 parts would fit the same in any other American or Canadian lower.
