View Full Version : New Yugo Underfolder: Single Shot Rifle
Ok, so my new Yugo is beautiful. Substantial, great fit and finish, etc. However, it goes: bang, click, retract bolt, bang, click, retract bolt. It will NOT feed a subsequent round. Three diff. mags in 2 different AK's were used with the second firing perfectly. The bolt seems to get hung up and stuck on something in the gas tube. It feels like you went empty using a Yugo hold open magazine. This would be something to look at if the gas tube would budge in the LEAST. I may be telling you about CAI's customer service in the very near future. Dread.
The mag. well on my new to me MISR Maadi is tighter than on my Yugo too. It however had to shot on the very right edge of the target to get it to hit the very left edge of the target at 25 yards. Time to tweak and buy a sight adjusting tool. What a crap day at the range.
Also check your hammer/trigger assembly to make sure your hammer is not hanging up your bolt. Sorry to hear about your rifle. It's most likly an easy fix.

Rule 1. AKs do not jam
Rule 2. If rule one fails see rule 3
Rule 3. AKs do not jam
Just kidding
sorry you are having problems.
Can you pull your bolt carrier out of the receiver?
Is the piston dirty?
Sounds like it might be a "tight fitting hammer"
or maybe lack of a gas port.
How far does the carrier travel when firing a round?

Curious to know what your trouble is.
AK's rarely have problems, but there have been more since so many people and compainies have been making AK's with these imported parts.
Apparently its just as easy to screw up an AK build as an AR assembly.

The carrier comes out of the receiver, and the piston is clean...new and cleaned before firing. When fired, it would sometimes jam open with a live, unfired round holding it open. After a while, it would fire, and return to battery without loading a round. I can't check for a gas port as I can't get the gas tube off...

Oh man, you can't get your gas tube off??!?!?!?!
Thats not good.
It might be jammed on at a weird angle that is causing the rod to catch or something crazy.
I dont know, without seeing it or handling it it is just conjecture, but those two problems might be interconnected.

I am unsure of this, I own the same gun and have wondered,when you flip up the grenade sight does it switch the gas flow some how ? If so maybe the grenade launcher gas system switch isnt allowing it to cycle a round ?
Like I said this has just been a curriosity of mine,It probly isnt whats wrong.

On the Yugo AK and SKS , flipping the grenade sight up blocks the gas port in the barrel, all the gas exiting throught the barrel following the projectile. It will not blow any gas back into the action to cycle it. That's why milsurp's piston is sqeaky-clean. Easy fix.

Is the gas system on the Yugo SKS actually connected to the grenade sight? I thought you had to switch it seperately.
I picked up a yugo AK yesterday so if the leaf sight does block the gas system that's good to know.

The base of the grenade sight runs through and across the gas chamber and acts like a shut-off valve when the sight is flipped up in both the Yugo AK and Yugo SKS.
Rusty Shackleford,
You know that little thingie on the Yugo SKS gas tube you have to push in to get the grenade sight to flip up? that's the shut-off and it is connected to the base of the sight.

Oh man do I feel dumb.. been a long time since my yugo sks was out of the safe. You can't even raise the grenade sight without moving the switch on the gas system out of the way. :embarassed:
Sent a tech e-mail to Century. We'll see what happens.
Century says to send it back. I got a return authorization number. Since I did not buy it direct from Century, I have to pay shipping. What a crock, send out a faulty rifle and have me pay shipping to have it fixed. Oh yeah, 2-4 weeks for return!!! :rofl:

Sooooo.....the grenade sight is not what causes the rifle to shortcycle and/or not blow gas back into the action ? :shocked:
What is stopping the rifle is that when the bolt is retracted, it will not go into battery without further manipuation. It stops at the entrance of the gas tube. This has nothing to do with the grenade sight as far as I can tell. Also, I can't fully disassemble the rifle due to the fact that the gas tube WILL NOT budge to be removed. It's hard to fix what I can't see. The piston was not squeaky clean after returning from the range, it was cleaned before firing.

This sounds like
1) gas piston is over-flexing ( improperly installed in the carrier by the Century monkeys )
2) gas tube too long and was force-whacked in place by same "gunsmiths"
3) gas tube lock relief on tube not cut properly at the "factory"
or a combination of all three.
+1 on sending it back and letting them fix it :thumbsup:
Graveman,
my thoughts exactly. It had better come back in the shape that it was sent to them though. If I could take off the gas tube, I'd know more.

Milsurp, have you received it back yet. Reason being, I just bought two of these from Classic Arms. I went to the range this morning for the first time. One works flawless, the other presents the same problems as yours. While cycling the action by hand I feels much resistance compaired to the other M70. Tried several mags, same result. I just wanted to know if its worth it to send it back or just take it to a local gunsmith...Thanks in advance...
:dunno:
Hi, sorry to hear that you're having the same problem. I have yet to send it in. I'll do it Monday (swallowing pride about principle) and then have to sit out the wait (weeks) that they told me. If you send yours in, let them know that this is now at least two that have had to go back that you know of. Maybe they'll pay for YOUR shipping. If it comes back like crap, I'll MAKE them refund my money. Keep me updated.

Mil, lemme ask you this. When you invert the rifle so that your looking into the empty magwell, do you see resistance when you cycle back and forth. My action is so tight that it will stay open without a Yugo BHO mag in it. Also, mine hangs up just before it reaches the fully closed position (battery). Finally mine would not grab another round from the mag w/o having to manually cycle it by hand, if not you would just hear a "click" when attempting to pull the triggar.
Anyways I looked in the box that it was shipped in, and Classic Arms stated that the firearm has a 15 day warranty. I will definately call them on Monday morning...
Thanks
Yup to all conditions listed. The gas piston seems to hang up just before entering the gas tube, causing it to stay in open battery. It would not feed any rounds from three different magazines while firing unless the bolt was retracted manually. Extraction was perfect.

They(Century)will fix it for you. Might take a couple of weeks but it will be right when you get it back I bet. Sorry to hear about your trouble as I always recommend these M70 rifles on this forum.Perhaps a WASR magwell monkey put yours together.I had hoped they purged them by now.
Below is a picture of one of them:

I bought one of these and after clean/lube it was still stiff and the bolt wanted to stay back just like the hold open was engaged. I had just recieved the latest greatest stuff that is being used in the sandbox. It is called STRIKE HOLD www.strike-hold.com and I dosed the rifle with it and worked the action about 10 times and it ran freely and did not balk. I gave it another good spray(it dries up) and went to the range for about 3 troublefree mags. It is great to shoot. Now, I don't know if mine would have worked any way, but, it was very stiff. I bought a new bolt gun and I tried this stuff on it and it made a night and day difference in the smoothness of that action. Worth a try, I ordered online and they had it to me in about 3 days. I do not know these people or have any financial interest in them.
"The bolt seems to get hung up and stuck on something in the gas tube. *** What a crap day at the range."
Sorry to hear about that. Hope you get it up & running.
My AR carbine never does that. It just shoots and shoots. Deadly accurate too. ;)
Thankfully my (new) AR will be going with me to the range today. Hopefully all will go well. Had it for 3 months, unfired.

Well UPS just dropped off a nine pound package for me. Oh, its my Yugo which has been at Century for 28 days. Only difference, they replaced my gas piston. Everything else is the same. Thank God, I didnt get the new black plastic stock style. Range report to follow...
:supergrin:

And,,,
its going back to Century :faint:
I haven't even sent mine in yet. Your report confirms my fears. Will they do a refund? Or, what will it take from a unified front for a refund? Hint, hint.

Century fronted the shipping both ways the first time, as well as they are going to for this "Replacement" as well. Dont know how many rounds that they actually test fired before they give it the a ok, but obviously they didnt test enough on this one. I removed my wood, and boxed it up, (not to keen on the black plastic style). Their going to replace it for a new one. Hope its a winner :upeyes:
As far as customer service goes so far, it has been top notch, but the quality control is sub par...
Never asked about the "refund", but it will come up if this one doesn't go "bang, bang, bang, oh you get the point"
If you want the point of contact, just let me know...

Got the replacement from Century on Tues. Its top knotch. Excellent fit and finish, they even allowed me to keep my wood foreguards and sent me one with the black plastic style. Best of all it has the Zastava import info on the RSB. Oh and it went through 5 mags w/o a hitch. :supergrin:
Centurys got my vote :thumbsup:
