Noveske 16" Recon problems

I have quite a bit of field experience with the AR platform,
If it is holding open at 1' You have a gas tube issue.
The gas tube is bent and not aligned with the bolt carrier.
You will have to do some more closure inspection on the gas tube end.
No the gas tube should not be moving around, it is locked into place when you align the upper and barrel nut.
Make sure the tip is not damaged. If it is you will need to re flare it.
Look at the marks on the tip it will indicate to you how it is bent.
it is best to put a drill bit into the gas tube gently bend it back into place.
Once it's in place it should be secure and not move at all. If it does move around that indicates it's damaged at the barrel nut.
The gun is really fowled this also indicate a poor gas tube set up.
As for the bolt spring, it's a non issue add on. it is not required and will not effect the function of the rifle if removed.

If you have trouble understanding what I'm talking about or you need more info drop me a PM

That's a pretty broad statement from a Internet diagnosis

I mean the carrier key could be leaking as well -- too many issues to state a definitely issue without going through some trouble shooting first.

A number of Noveske lowers where out of spec in that the bolt catch sat to high -- it really only seems to cause issues when trying to mount a Hk416 upper (FYSA)
Also as the gun worked for a bit then stopped - seems that that issue is unlikely - unless it caught a burr and is retarding cycling (which you seem to insinuate it does not.

1 get a known good mag - which a known good ammo (not NORC for god's sakes)
If issue continues
Swap Bolt Carrier from NORC
Try again

also Pictures help -- but best is to link with BenL and troubleshoot it in person
 
Hey guys,thanks for all the responses,much appreciated.Earlier today i tried one suggestion,to try to cycle a round slowly and see if my issue persisted and it did.I was always told not to ride the cocking handle or else issues would arise and thats what happened.I dont ever rememeber doing it and having issues arise from it in the past tho.Do you guys have issues when purposefully riding the cocking handle?

Im gonna try to head out to the range this weekend and try and troubleshoot some more by trying all of your suggestions although i still think its a gas tube issue like Weenog suggested

Update.while writing this reply i went and tried cycling slowly again and again it stopped short,but i tried my norc AR and it did the same,using the forward assist took care of that.

Im gonna report back after testing the rifle out.Below are some pics ,might help with this issue.

First pic shows two allen head screws that i presume are to dismantle and seperate the rail from the rifle,anyone know if thats the case and if its that simple.Ill attempt it if it let me gain acces to the gas tube.

A variable changed in that during outing #2 the rifle worked flawlessly, but returned to the equation during outing #3 and that's what I'm trying to wrap my head around.

####ty mags only? Nothin' new here.

####ty mags and a out-of-spec mag catch?

Out-of-spec mag catch only? That doesn't fix itself one day and returns another so I could be way out to lunch.

Proper lube one day and not the other w/ -25c Vs -5c weather?

I need another coffee.
 
Do you need a lot of force to close it with the forward assist? If no, you may need to see if you recoil spring is too old or not in spec.
 
Hey Hamburgler,

I can't help you with this issue; however, I wanted to say "Hi" and "Good Luck" with your rifle. I was the guy who was beside you at the range last Saturday on your rifle's Maiden voyage. I look forward to reading about the resolution of this issue. Have a nice day.

Regards,

Chizzy
 
Any time you ride the charging/cocking handle you are slowing it down, so the bolt may not have enough inertia to lock close while trying to chamber a round.

That idiocy during the initial C7 fielding (to reduce wear in garrision/training) gave a lot of training scars that still pop up on some folks 20+ year later (though it finally got removed from the pam).

Whenever a live round is being chambered - never ride the action.
 
the end of the gas tube will have a certain amount of flex and can move around a bit under finger pressure, but once pressure is released it should return to center. it should not move if the rifle is shaken. the end of your gas tube looks ok, from the picture you have posted. if it seems to move very freely, then it is probably loose in the gas block, or your gas block is loose, which may also be the source of your function problems. remove handguard and check gas tube and gas block.
 
Well i think ive discovered the issue.Went out to the range yesterday and went thru everything everyone suggested and decided to visually inspect all my mags again and it turned out my cheap norc mag was the culprit.It had a slight lip of extra metal at the front that rounds were catching on,causing the bolt to slow,then the round would get sorta caught/slowed further in the chamber lugs and so that stopped the bolt altogether.As soon as i bent the lip back a bit the mag and rifle worked flawlessly.

Thanks to all who threw in a suggestion on the issue.Im still not happy about the movement in the gas tube but im going to take the rail off and check that out today

Hey Chizzy,thx for the support

Glad it worked out. Nothing like working with ####ty mags to ruin a day of training at the range. Good timing as ATRS got a new shipment of their AT-15 pistol mags.

There is no way that the gas tube can be tight in the upper.
The end of the gas tube that fits into the gas key is larger in diameter then the actual gas tube therefore the only wait for the gas tube to fit through the hole in the upper is if it has the clearance to do so.
 
Gas tube being not affixed to upper is what can allow for the true free float of the barrel. Some uppers have more room than others - but as long as it does not impede the bolt travel, and is not worn out - don't #### with it
