So I just bought myself a Norinco m4 and put complete Stag Arms lowers on it (better quality) and now I want to replace the upper with a stripped one from Arms East. On the site it says this
"ONLY FOR USE WITH BARRELS WITH A TRUE M4 BARREL EXTENSION. If you don't know if this applies, or have a barrel with other spec feedramps (not all "extended" feed ramps are actually true "in spec" M4 ramps),"
Which brings me to my question... does the Norc M4 have a "true in spec" M4 ramp?
