Hi friends recently I got a New Norinco 10.5" CQB upper minus the BCG came with CH , I put a CMMG FA BCG in the upper also tried a Spikes tactical FA BCG fit seems very tight and not all that smooth I have CMMG , Colt Canada , bushmaster , Colt and none fit like this Norinco I mean it fits but its much more close fit and less smooth action .
Are the Norinco BCg's Milspec ? Thanks for your input and advice I am guessing this will not be a very smoothly operating upper .

Yes it is within Chinese Military Specification ;)
Even US military Specification there is a lot of wiggle room in the acceptable tolerances. As long as it functions it is good .
 
At first I thought it was not going to go lol I mean I can just slide the BCG into all my other uppers without having to do much alignment or muss or fuss lol this puppy was certainly not the same , although the upper looks very handsome :) that being said it has a US made quad rail on it .
Will be interesting to test it next to CC , Colt etc see exactly how it functions , Saturday night Ar15's lol
Thanks for the input Gents

I ran a BCM FA BCG in my Norinco never had a problem shoots the same as my DD, Colt Canada, etc... It was tight at first also, I ran it with grease (AeroShell 33MS) for the first 700-800 rounds.
