Does anyone know if the Norinco upper will fit on a standard Colt AR15A2 lower?
My Colt AR has the 20" barrel and fixed A2 carry handle. It also has a match trigger in the lower. I'd like to have a shorter flattop upper that I could swap out for CQB matches (and just plain fun
).
The Norinco M4(gery) seems to be the most budget-friendly way to accomplish this, but I need to know if it will fit. I haven't got the foggiest idea if the pins in my Colt lower are the large or small pins.
Any info will be greatly appreciated!
