Norinco cq a 5.56

I use the Norc M4gery for CQB. Works perfectly.

I have made 3 mods:

Floated the barrel using a $39 tube from Brownells. Don't know why I did this. Does nothing for CQB, but always wanted to float a AR.

Ground the lever off the right ambi safety. It was hitting my knuckle.

Installed a Rock River match trigger. The single best thing I could do to the rifle. A great trigger.

Thanks for the feedback guys. Got to say it is one huge resource to have an online groupe like this. I bought the rifle new from Milarm. I don't think they will help but I will give them a call today anyway. I say this because Marstar claims that there is no waranty on norinco and that only Marstar offers any waranty on notinco products. I never thought of the dust cover trick but I will try it. The bolt moves smoth. NOW. The first few shots (bolt action) were stressing because not only was it not cycling but the bolt catch was working very odd. Somtimes not engaging on an empty mag. Other times not disengaging when I pressed on it. I drop of oil in the bolt catch channel contacting the bolt catch solved that. No odd feel however to the bolt travel. Certainly not as smooth as the Colts I owned in the past but smooth enough that I cant see there being a problem from friction. It is as smooth as other Norinco ar's that I held.

Thanks

i bought mine from milarm too, talk to them, my experience with them is that they would try to make it right.
 
I had the same problem with mine after 100 rounds. Being a an obsessive engineer, I wanted to get to the root cause.

Conclusion, bad mags. The follower in the cheap factory mags is painted aluminum so after the bolt scrapes the paint off, the aluminum drags the bolt enough on the last round that it does not hang open.

I bought the Magpul P-Mags with the green Teflon anti-tilt followers which resolved the issue 100%.

I just found this out myself. The bolt dragging on the aluminum follower slows it down so it won't stay fully open and snaps shut when you drop the mag. Works perfectly with the P-Mags.

Since I do a lot bench testing I was wondering if the followers could be changed on the cheap Norc 5/10 mags just to make it easier for me.
 
I am going to try the 3-pack of Magpul self leveling followers for $10 from GPtactical.com

It's plastic so it can be shaved down to capture the spring.

If it works, two new re-built mags.
 
got one , had a feed issue was catching the spent with new round and jaming, polished ,played , adjusted would still jam every mag. then this guy walks up and says lets check them mags. lar10 rounders, filed some edges and no issues since , except a sore back from picking up all the brass all over the place :)
 
I found that I would get jams or fte when I used those crappy heavy expensive mags. The light mags I got for 15 bucks each work well and have low pro followers.
 
I need to replace the ejector spring as well as the extractor spring on my 10.5" Norc, can anyone help suggest where I can go to buy just those springs? Thanks in advance!!
 
just got mine out to the range, 470 AE black box and 30 or so of my own reloads.

0 malfunctions
0 problems
0 issues at all

clean after every range trip and liberally apply castrol wheel bearing grease to the bolt and BCG and youre good to go :D
