is there any differance in reliability between the two .
Ive heard that the 10.5" has been picky, with ammo selection, regarding cycling .
 
I have the 14.5" Norinco CQ and it has been flawless so far. The 10.5" Norinco CQ, from what I have read on the forums, may still have some issues to work out. Some work great others not so much. Just luck of the draw I guess. I was at my range yesterday and the guy next to me had the 10.5" CQ and was trying to get it to function properly but didn't succeed.
 
I have the 10.5 '' CQ-A and i've put around 250 - 300 rounds through it so far, never had any cycling issues just som FTF with the 5 round factory mags using HP ammo.
 
yea im thinking, i want the 10.5 ,
its just what im looking for .
i have the vtr-15 preaditor carbine cs.
its a fantastic rifle.
so the little 10.5 cq-a whould be great.
just a bit concerned with reliability of it .
if the troubles are just mag related then not a big deal ...
 
Bought a 10.5" couple of weeks ago.
After breaking it in and cleaning it really well a couple of time, oiling her up, we had it out a few days ago. About 200 rounds down the barrel without one failure. Nice rifle! And with the 10.5" barrel you get the added benifit of making all the people beside you one the line just every time you fire the thing.
 
I cleaned mine before I took it out. Removed the rag from behind the bolt carrier group...............:confused:

Spooksar coached me on lubing the carrier group. Better to run "wet" with oil or grease, then dry. Grease is for a training type course where lots of ammo will be fired. Oil will evaporate with heat. Grease will need extreme heat and time to dry out.

I used the Federal black box 55 grain 223. 2 boxes of MFS 55 grain stuff.

Only issue I had was not seating the mag properly one time and not stripping the rounds from it. :redface:

I used the D&H mags that SFRC sent with the rifle (5 free mags came with it) and the 2 short Norinco mags.

I was befuddled I had no issues. Cause I was expecting them..........
 
Use both. Lube and Grease. High temp wheel berring grease and synthctic motor oil. Dont by into this "gun lube" crap. Its a money grab. I challenge you to use use the products I have stated and find better results on any type of firearm.

Grease your contact points on the carrier, bolt and pin. Lube the lugs.

As for accuracy, yes there will be a difference at range. If youre using a PDW/CQB Build for its intended purpose, no you will not notice accuracy loss. It all depends on what purpose you intend on using this rifle for.

is there much accuracy loss with the 10.5 vs the 14 ? I am deffinitly buying one or the other i just cant make up my mind.

Accuracy loss would be very little if firearm is going to be optically sighted, and never fired beyond 200 meters.

The shorter barrels sometime do show enhanced inherent accuracy, due to being more rigid, with there more uniform harmonics. Of course,.. this is only evident at closer ranges, and while being fired from a supported rest.

Out on the 300 yd line, the lower velocity out the 10.5" barrel, should start to show up, causing more drop, and more drift between each round fired. This in itself, can be a big group opener of epic proportion, and not from the barrel's accuracy itself.

If you are shooting over the irons with a 10.5", the same size front sight will appear larger in your sight picture, and cover more target at "Rifle distances"!

The shorter sight radius, the distance between the front and rear sight, will magnify sighting errors more. This is why a 2" barrel handgun fired at 100yds with a 1/64th errror will give a 1 foot miss, but the same sight error between shots with a 30" target barrelled rifle with nearly 40" of sight radius, may only stray by an inch or so. This is extreme for comparison purposes only.

Even the 14.5 " barrel's standard size front sight width on my Mforgery, covers alot of a figure 11/59 at 200yds. A National Match front sight would be alot better for these carbines in my mind at 100 and 200, where they are meant to be fired.
I've never fired the 10.5", but I've seen the handicap with iron sights going from a stangard GI lenght A2 with 20" barrel to the M-4 with 14.5", and is quite noticeable at 200yds. I'm guessing the drop from my 14.5 to 10.5 would be similar.

If you're into CQB, or like to plug away off hand on the 50yd line, these handgun distances, won't matter to either barrel length.

Personally,..I've always loved the look of the original Colt Commando with it's 11.5" barrel, so if you're not into competition with iron sight's past 100yds, I say try the 10.5". They look sweet, but make sure they don't short stroke.

The 14.5"s, seem to run flawless, as long as you've got good US mags. Mine had the Nork mag's changed out by dealer before I bought it. Maybe the mags may be a problem for the 10.5" guns as well. I'm not sure what Norinco has done with buffer's and gas port's on these shorties.
Maybe someone with some data could help us out here.

Well put.
 
I ended up buying both a 10.5 and a 14.5

To be honest they are pretty equal, and it comes down to what you want.

i like the 14.5 but is onluy a pesonal choice. i like the feal of the 14 it balances better for me.

but on target it they are equal.
 
I got the remington R-15 preadator carbine CS.all scoped out for long range target.
it got a 18 " barrel
so i want the nice litte 10 "er, with irons.
i think the norc will fit the bill, perfectley,
i just heared some reliability issues, thats all
guess there aint much to be concerned about after all ..
Thanks guys ...
