Tavor failure to feed?

I gave up on mine and sent it in for servicing. Will be months before I get it back but the thing was useless so it's not like I was using it.
 
Just wanted to chime in on the 'problem with the Tavor' thread. I bought mine back in June, from Italian Sporting Goods, here in Vancouver and have had problems with the bolt hold back. Out of say 20 magazines worth of shooting, I might get one where the bolt hold back actually works. And I find that ammunition is another problem with mine. I find that it shoots the Norinco stuff OK, but I've got some other surplus that the Tavor just will not shoot. Lots of failure to feeds. I am at the point where I'm thinking of sending mine back to North Sylva and see if they can diagnose the problem. They told me I need to shoot a heavier grain cartridge than the standard 55 grain that I always shoot. If I do that, they say the bolt hold open should work, but I've heard of no one else having this problem.
 
The bolt hold back usually does not engage if the bolt does not travel rearwards far enough. Since you have ammo issue with failure to feed (ie, your bolt may not travel far enough to the rear to strap a round off the magazine), I suspect your rifle is under gassed. The TAVOR bolt carrier and op rod look pretty fool proofed, so most likely it is a gas block or gas port issue. Don't attempt to just cut the recoil spring.

The easiest way to diagnose this issue is to get a set of bolt group from a TAVOR that works. If your TAVOR still malfunctions, you can be pretty sure it is the gas block or something in the receiver that you cannot do it yourself. You probably want to do that so you can tell the distributor what it is wrong so they don't have to take multiple trips to the firing range to figure it out themselves.

If it is indeed your rifle has a bad gas block or gas port in the barrel, most likely you will need a new barrel assembly. It could be also that the op rod is not true to the receiver, but that will be a barrel assembly issue as well.

Thanks Greentips. Sounds like sound advice. I would probably have trouble finding a bolt group from another Tavor to test out your theory, and diagnose whether it's that or the gas block or gas port. But does it seem reasonable that I should be forced to shoot a heavier grained cartridge to get that bolt hold back to work? That's the advice I got from North Sylva and that just doesn't seem right. The vast majority of surplus .223 and 5.56 that I have is 55 grain.
 
I just got my rifle back from north sylva a few days ago.

The video illustrates the issues I was having. Basically the gun was a bolt action rifle due to short stroking which wouldn't strip off a new round. I also had double feeds and the odd stovepipe. The biggest issue for me was that, while it would happen with any type of ammo I used, It wouldn't happen every time. Making it hard to figure out. I sent it to north sylva. One day it worked for them, the next it wouldnt'. The tested it again after "cleaning carbon from the piston" and it shot 250 rounds just fine. They shipped it back and I have put about 200 rounds of norinco and American eagle through it. It works fine now.

To me, The explaination of the gun being dirty doesn't cut it. I cleaned the rifle very thoroughly before testing and sending it away, including cleaning the carbon off the piston. BUT, I cant really ##### too much because whatever voodoo they did seemed to work because the rifle is back in working order.

The weight of the bullet has nothing to do with it. It is the port pressure that counts.

That norinco stuff ( from the spam can) is pretty hot.

I don't know what surplus ammo you use. If it doesn't shoot good factory (Winchester, pmc or federal AE )223 (not 5.56)with 55gr bullet, the rifle is the issue.
 
No, I think I'm staying clear of the mag release while shooting, but I'll double check next time I'm at the range.

Thanks to you all for your replies. I think in the end, I'll end up sending my Tavor back to North Sylva to have them look at it and hopefully diagnose the problem.

And thanks for the video Redbearded1. I have taken similar videos to back up my claim of disfunction with the gun.

It's too bad, cause it really is a fun gun to shoot!

Thats weird, the bolt closed but didn't grab the next round at all, i could accept the dirty explanation if it had somewhat grabbed the round but had a failure to put it in chamber due to the action being weak because of friction on the piston due to deposit, but it didn't grab the round at all.

Maybe the bolt didnt cycle at all and just stayed closed after firing which would be pretty weird, also that would need some major sort of deposit for the action not to move the bolt at all. Maybe it cycled very weak i.e not strong enough to go back enough to clear the mag and get a round?

I'm sure that's exactly what was happening. The bolt was short stroking and not stripping off a new round. I'd like a more definitive answer as to why it was happening. Being fouled makes sense the first time it happened, I had ran a few hundred rounds through before cleaning it while on a training course. But at the time the video was taken, the gun was clean. Spooooooky.
 
Folks, since I started this one I figured that I'd close the loop.

The gun went back to north sylva for repair. I know that some people complain about slow comms but I suspect that it's because of the workload they're under. Having spoken with them a few times I can say that they're great to deal with.

The issue with mine was probably a damaged gas cylinder. It's very easy to damage it if someone isn't careful taking the gun apart. I truly believe that no one should do anything further than an operator level takedown.

So it's back and functioning with all the mags I have on hand that we're having problems before.

i plugged my gas system with "wipe out" once and it was doing the same thing. take your guns apart and CLEAN them. there great rifles if you take care of them properly.
