Norinco M4 CQ5.56 Reliability - You Decide

Try to avoid the 45 grain stuff, a lot of it isn't crimped for use in semi-auto rifles, and the bullet is too light to properly stabilize in an AR (much of the time). Also given that the Norc is running a carbine buffer and F/A BCG, it may not have the required energy to fully cycle the rifle. Oh yes, and run it damp, except for the buffer - don't lube the buffer!

Bang on! I would like to add that the 1:9 Norc M4 barrel does better with the 55gr + ammo.
 
Sorry Airborn, DASQ is right on this one. All guns run better clean, they will work dirty but why risk it?

Not saying that it is wrong not to clean your rifle...I was refering to this & there is a difference between over cleaning & field cleaning.

Given me this problem last few times at the range. It has been cleaned so well, yet it may fully cycle for 5-10 rnds, then it screws up again!
 
If your gun actually needs some grit and gunk to function correctly, you have an issue with manufacturing tolerances, not with design.
 
ARs are very simple, if it is not dirty and its lubed but still have stoppages. then your gas rings are worn.
Easy way to test this, is feild strip your bolt assy and put the bolt into the bolt carrier. Hold the bolt head and let the carrier hang, If the wieght of the carrier pulls it off the bolt, then your gas ring are worn.
 
Another 150 down range today. Not a problem.

I used brake degreaser with gloves on and just went to town with it. Completely tore it apart and degreased it.



Hung it from my garage roof by its muzzle brake. A bit of rag in the muzzle brake and mag well. Took out the bolt. Gave the body of the rifle, handguards and mount a light coating of speckle stone granite to rough up the look. Let it dry for a good couple hours and gave it some light coats of Krylon Khaki, brown and olive.

Ummmmmmmm that's about it. I did have to scrape of some paint on the handguards to get them to fit properly and front sight and to work the charging handle a few times but otherwise than that was it. Pretty basic.


Let it dry for a few days and took it out. Carefull with wiping the exterior down with cleaning oil as will take off the finish if your too aggresive. Give it a go. If it sucks just spray it down with WD40; wipe it all off and try again.


Have fun and take your time :rockOn:
 
I just want to give a post 1k rounds review:
Stock Norc w/
UTG Rail
TD stubby grip
t1 micro with larue mt + 3x magnifier
no name single point sling bungee with ambi sling plate
DPMS LPK including trigger pkg with the trigger job done.

For comparison:
stock Stag same length
acog
rails
laure grippy

Weight comparison - Although not scientific, without the optics, they both weighed the same to me.
Shooting comparison - Given that my stag has well over 8k rounds through it, its been well broken in, I have to say that I'm not afraid to run the norc to the ground. Its been raped and abused and finger-banged up the ying yang. and for all intents and purposes as a cqb type rifle for short distances up to 100m, it does what it needs to do. consistently. I did not benchrest this gun at all. Just standing, kneeling, prone, and run and gun contact drills.

Shooting the stag, feels the same. I say feel, because I have no way to measure, scientifically, any of the variables of shooting. Just that the holes are on the mark, or I hear the gong.

The upper flat top. Is tight. I won't say that it is necessarily 'mil spec'. but it seems to allow moutns of various types to lock up tight with no rattle. As with all things screwy - use loctite.

Heres' the caveat emptor and theres a few of them:
DITCH the factory mags.
they are s**te. ftf. lots of tap rack, then. rack rack rack..
good quality metal mags ( I don't have pmags) like the rra 10 rounders or cmags or whatever with good followers allow the ammo to feed properly.

Ammo: don't use the cheap bulk pack stuff of the hollowpoints. they ftf, even in good mags. use fmj. Probalby something to do with the feedramps. I'm not about to go and tinker with it, and look for what the issue is. I just want to know that it shoots, and what it likes to shoot, then just stock up en masse. std 55gn fmj from wwb is good enough

One thing about the flash hider. shooting on the prone kicks up dust. its a bird cage flash hider that has holes on the bottom too. I think it might be better served to replace with something that doesnt.

Trying to mount a quad rail was a #####. the stupid cap thing at the FSP is odd shaped, so it won't accept standard drop-in rails. I had ended up using a set of spare utg ones that have the screw tightening. If I didn't already have a spare quad rail, I'd proablaby end up with a troy.



After 1k rounds, I feel it is broken in. And it was given its first detailed strip and cleaning this past weekend. meh, dirty as expected. Usually I just give the entire bcg a wipe down with clp, run a patch through the barrel, but this time, went all out.

I did install a dpms lpk for the trigger group only, replacing just the springs and the trigger assembly. imho, world of difference. I now keep the norc lpk as emergency spare.

I am very pleased with this purchase, its probaby THE MOST bang for your buck, to get anybody into the ar15 game. The fact that it is modular, and is compatible with other systems, such as the ciener 22lr conversion kit, and can accept other uppers and other bits and pieces, makes it a very very super duper fantastic gun.

*Edit to add that it accepts 27rds BDM just fine.

In the near future, I'm going to change out the grip for something more comfortable. YOu either have to wear gloves, or suck it up with the pain after a couple of hundred rounds and manipulating the gun with the standard grip. i'm a pansy

Ecuse the s**tty picture taken from a s**tty phone cam. Left is stag, right is the norc:

Regarding the mags, P Mags work just fine too (as you might expect). Have you played mix and match with your Stag yet? Run the Norc upper on the Stag lower and vice versa. I really wonder (especially with the Norc upper) how much of a difference you'd see.
 
No I haven't. Good call will do that. I will try a 3 variable matrix:
Norc Upper, Norc BCG, Stag Lower
Norc Upper, Stag BCG, Stag Lower
Stag Upper, Stag BCG, Norc Lower
Stag Upper, Norc BCG, Norc Lower

I shall use whatever ammo I have on hand. probably pmc or wwb. I'll stick to using my RRA 10s as thats what I use for classes and comps.

I suspect, there may be a bit of play between the uppers. but if truly 'milspec' bcg's should be just fine.
 
300m, the gong goes bang everytime..

Haven't made it to 400-500 yet since there is no range far enough in the area.

Just a rant. I don't know of any ranges in the Ontario that goes beyond 300yards. If there are, it's too far from me... If the AR was non-restricted, we can technically find a clearing in the bush to test it out, and I think I found my spot.

Besides the AR108, closest evil looking non-restricted I can think of is the Tavor.

My head is spinning again. Our laws are completely messed up. Eventually, all our evil looking firearms will become restricted or worse. :-(
 
Looking at all the 'evil' non-restricted firearms and still being able to own other 'evil' looking firearms that are restricted makes no sense. Logic dictates that it makes no difference at the end when it comes to safety. Only benefit is, our AR would probably not get stolen in the trunk, but the Tavor will since we can take that across the country without ATT. That said, logic dictates that if one cannot 'steal' a firearm in someone's trunk, one can still buy one off the streets, imported - not stolen from another Canadian.

A 30" shotgun, and be cut down to 12", but that would make it prohibited, but I can buy 12" stubby that is non restricted. LOL!

I'm getting a head ache. Sorry for ranting again.
