Took my Cetme build to the range ,couple problems.

[vista461]

Finally got my Cetme out to the range. Good news, it didn't blow up:lol2:
First thing is I'll need to move the triple tree over, no biggie that's why I didn't pin it yet. The bigger problem is it's a single shot. Fires fine, Ejects great. But the bolt gets locked to the rear after each shot. To get it to release I have to take off the buttstock, so I only fired 12 shots before I got sick of the slower than Muzzleloader pace.:lol2:
The bolt carrier would release just after I started to remove the stock, before it was all the way off the back of hte receiver.

Any ideas?
Maybe a bent guiderod? I only brought the black widow stock so I don't know if it would have worked better with the stock/guiderod that came with the kit. It never happens when I use the cocking handle.

The recoil feels different than my other rifles, even the AK felt sharper, I am going to like this one when I get it running right.:rockon:

On the plus side, it did feed the top round off of the G3 mag, cetme mag and the US made mage I have. It ejected good and strong too.

[rifleman]

could be guide rod. with ot it how well does the bolt carrier system move back and forth. does it get stuck. and check your mags, are the getting worn. make sure they arent sticking to far up the mag well. lastly make sure it is well oiled. do all that and report back

[texlurch]

Sounds like the receiver is a little tight on the rear, and sticking the carrier back. My G3 did the same thing until I lubed the crap out of it and ran a couple hundred rounds thru it.

The fact that the receiver is a G3 pattern, and the CETME stock housing has a slightly different shape causes things to pinch a bit.

When cocking with the handle, the carrier doesn't go as far back.

[turbothis]

might have a bur somewhere, a bent rod, a little out of shape on the rear of the receiver. i have good luck with tapping sheet metal over the bolt when they stick. if the bolt is stuck in the rear get a dead blow and smack it aroung some. this might relieve the tension.

[vista461]

Its a stainless rec if that makes a difference. The bolt slides in fine when I am assembling it. I don't think it's the mags because it still was stuck when I took the mag out each time.
I'll take it apart again and see if I can see any rub makes inside

[jfowl31]

check the spring retainer pin onthe guide rod as well. I would guess either the pin, a bent rod, or a tight buttstock. Doesn't sound like anthing that can't be fixed. If nothing's bent or protruding, I'd just lube the hell out of it and run some rounds through.

Also, when back at the range, try smacking the butt on the ground to release the bolt when it gets stuck. Normally works and is much quicker than taking off the buttstock.

[pigpen]

After a good cleaning, my CETME was doing the same thing. I just lubed it up and it started shooting like normal. I hope that is all your problem is.

[vista461]

The guiderod did seem tweeked a bit, I think I got it straightened out. Pin wasn't sticking out. Hopefully soon I will be able to test fire it again. I think this is my new favorite gun. Either this or my AK will be my deer gun this year. That makes them "sporting rifles " right:wink:

Pardon if this sounds dumb but there is a buffer system bolted in the butt housing? Check to be sure it's working properly,especially if there's a deep outline of the back of the bolt carrier freshly imprinted into the inside of the housing,or roller dimples forming at the rear of the receiver.Otherwise,I vote for malformed rec. at the rear,you may have to inspect inside for the finish rubbing off and Dremel some material for best fit in those spots. This would be a cheaper fix than chunging a couple hundred rounds at a c-note!

[texlurch]

I shoot a couple hundred for a range trip anyhow... :)

Yep buffer is there. No roller dimples or imprints. Bolt slides freely when assembling and receiver shape looks fine.


I have some Shooters choice "high tech" grease. Should I rub some of that on the rails? Or just use a lot of oil maybe? I am thinking maybe the problem is/was a combo of the little rougher finish inside of the SS Cast receiver and the tweaked guiderod

At my firing rate I would been there till this morning for 200 rds :lol2:

[danielsand]

Well, I am a newb on this site, but at 53 years of age, and 21 of those in the uniform, I do have some experience. So this is MY opinion.

This being a cast SS receiver, I don't think that the butstock is pinching it to the point of getting stuck. This is common on stamped receivers, matted to original HK stock.

The way I would approach this,....clean the receiver, and the bolt carrier carefully, spray some flat black paint inside of the receiver (sparingly and carefully!), assemble, and shoot couple of rounds. When it gets stuck on the first round, just hit the butstock on the ground, and it should release. After few rounds, disassemble and look for the rub marks. If no obvious point of friction is found, your problem is in the recoil assembly. If the friction is in the receiver, clean the paint out (should just wash out with a shot of CLP), and sand the contact area of the receiver with wet sandpaper, following with "Mother's" metal polish (use 12ga mop mounted on the drill!). Once the innards of the receiver are nice and smooth, lube with lithium grease, and go shooting!

If the problem is in the recoil assembly (rod, spring, buffer)....replace the whole stock and don't look back!

[vista461]

Sounds like a good idea. I will also bring my spare stock assembly with me next time.

[MID]

one more tid bit of some thing to think about.
If you need to have that gun prefectly cleaned and lubed just right to work, then you still have a problem.

[cfish]

Vista I would recommend you lubing the rails and carrier with a grease type lube and not oil. The oil leaves the bolt to quickly. Tw25 or its equivalent type lube will stay on for hundreds of rounds. DO NOT get oil and grease lube mixed as the oil will break down the grease type lube.

[vista461]

Thanks for the tip. Haven't used grease in my other guns, it's a new thing to me :thumbup:

[97th Signalman]

Do you happen to have any sort of optics mount clamped on to the receiver?

[vista461]

No not yet

[vista461]

Well took it out to the land where I go hunting this afternoon. Holy Mosquitoes. Didn't stay long because I was getting eaten alive and ended eating two of them.:lolgreen:
What I changed before this time was, turn the triple frame a touch to hopefully get the sights closer, lightly grease the rails inside the receiver, and attempt to straighten the guiderod. Well I loaded one in the mag, and fired. Same crap:wallbash:
So I change the complete buttstock guiderod assy with the one that came with the kit, at a record pace since I was getting eaten alive. Load one in the mag and fire. Works perfect. Load 6 in the mag, shoots perfect:rockon:. Packed up my stuff and got the hell outta there while I still had blood in me. :)
So looks like it was the guiderod or something to do with the backplate.


So my first build WORKS:rockon:
I'll have to wait till next time to see if the sight change worked, to many mosquitoes. I just fired it into the berm to check for function.

[KMURPHY]

Awesome Jamie...glad to see that your CETME works now. We have to plan a range trip one of these days.

[vista461]

Yeah we should. I need to get it all one color now :)
It looks like a car with mismatched panels.:wink:
