My Norinco M14 is easily one of my favorite rifles. Purchased before they became readily available up here (from Marstar) I paid $500 for mine in used condition. It came with a cloth sling and a standard “Chu” wood stock which was unfit for firewood. I wasted no time acquiring a USGI stock for it, added a bipod and picked up a B-Square QD scope mount for the rifle (pics here)

The B-Square mount was a problem from day one, even with loctite it would loosen off rendering the scope entirely useless. The B-Square mount was replaced with an ARMS18 mount (although mine is the older version with short segments of rail at the front and back). Money from this point was spent on accurizing the rifle rather than the asthetics (for the most part).
The Norinco trigger group was replaced with a USGI TRW trigger group, the “solid” flash suppressor was replaced with a current manufacture NM SA version (as was the rear sight). The Op Rod was replaced with a Rooster33 NM OpRod, the gas system was shimmed and the OpRod guide was locked down. The stock was repainted OD and the sole remaining area for upgrade remains the optics, which is presently a Tasco variable magnification scope that is not holding up to the beating the rifle is delivering.
