HK 22 conversion in a Cetme?

[Groovy Mike]

The Cheaper than Dirt catalog lists a 22 conversion kit "no gunsmithing required". Am I correct that this kit will in fact NOT function in a Cetme?

It seems to fit in the rifle, but will not function.

Thanks for any input.

First off, I don't know but maybe we can learn something. Do you already have one and it doesn't work? The barrel insert should be fine, the barrels interchange. The trunnions are different. Does the .22 bolt have anything like rollers or is it just blowback? (assuming you have one already).

[SSwee]

Besides the trunnions being different, the bolt carriers are different lengths on the recoil tube.

I haven't figured out how it supposed to fit, I know the barrel liner will probably fit, but the bolt carrier assembly of the HK is different than the HK. It'll probably slide into the Cetme but I the HK bolt carrier is slightly shorter and the way it interfaces with the cocking mechanism is different. So it'll probably slide right in ok, but no cocky!

[drine]

I wonder how the .22 carrier is made? If, and that's the biggy, the part that goes inside the trunnion was a non-issue, I'd cut the tube and weld a CETME compatible one on the end. I bet Turbo could make it work!:rockon:

Good pics, I have never taking mine apart to the cocking tube!
Now I know what it looks like!

I guess my question woudl be would you be willing to cut up a $500+ 22 conversion kit plus an additional CETME bolt carrier just to shoot 22 lr out of the CETME, $500 buys a fair amount of ammo, not to mention destroying a collectable 22 conversion kit.

$500 would buy a few 22 cal rifles!

You bought the CETME so you could own a CETME and shoot the round that was intended to be fired from it? To pay 300 bucks more to fire 22lr from it would not only be an insult to the fine rifle you own but an injustice yourself. If you wanted to fire 22lr might i suggest a 10/22 at half the price. It's a great rifle and fires 22lr. Don't get me wrong I understand ammo times are getting tough, maybe you might wanna get into reloading? If you do I'll be here to help you along, and I'm sure other folks on here will help as well.

Agreed, some ideas are best left as just ideas.

get a gsg-5. hk look but fires a .22lr. problem solved. damn i'm good.

What he said!! :thumbup:

Also Cohairie is supposed to be coming out with a 22 version of the gun too. Of course it'll probably be 3 times the price of the GSG-5.

the reloading help will come easy. everyone has been a great help to me.

[Otis61]

Another thing about these .22 conversion kits I always worried about is: when you fire many, many rounds of .22 through it, which is why your doing it, does all that vibration and movement damage the rifling of the original barrel?...... Anyone?

[Groovy Mike]

you guys are missing the point. The 22 kit lets you practice handling your main rifle and train new shooters without burning expensive 308 (have you priced it lately?).

[badmojoman]

You could shoot this but you'll have to cycle by hand.

Its cheap enough but your arm may get tired. I may get some for my bolt action.

Dans sports sell the bolt and the practics ammo. I think we have bin through this before .LOL:icon_biggrin:

[okie shooter]

On useing the 22 conversion, if you change the thing to blow back, then as long as the barrel fits, you can put that in. By changing to blow back, it does not need to cam to give you advantage to unlock the rollers as they are not in the system. In my opnion as long as the bolt carrier will close you will be ok. I would have to look at the pics of the bolt carrier to see if there would be an interfearance with the cocking handle assembly in a cetme vs a g-3. If the g-3 is shorter, I think it would work.

[drine]

Blowback. I'm assuming all along it is blow back only. No way a .22 could unlock the rollers as is and I can't see how it will do the blowback with a full weight carrier. That's why it has a special carrier. I'm just interested in seeing if it will go in with no adjustments. We need a guinea pig...Groovy Mike, are you gonna do it?:icon_biggrin:

[rustypirate]

IIRC the tube on the G3 bolt carrier is thicker than the CETME.

[okie shooter]

Rusty, would the carrier thickness preclude the carrier from fitting and cycleing in the tube assembly of the CETME?

[rustypirate]

maybe, stand by while I check.

[rustypirate]

OK, the CETME carrier that I measured has a tube diameter of 16.91mm, while the G3 carrier I measured has a tube diameter of 18.06mm, mote than 1mm of difference larger for the G3 carrier tube.

I tried to fit the G3 carrier into my CETME rifle and the carrier stopped hard on the cocking tube and would not go in at all.

This is in a CETME built on a Century CAST G3 receiver with the remainder of CETME parts.

To me this is pretty difinitive, but your mileage may vary.

[Groovy Mike]

At $17 per thousand I'll shoot ball!

I bought the HK91 conversion kit and it runs fine in my PTR91 (but not in a Cetme). But I just don't use it that much. So I'm putting it up for sale. I paid $550, I'll ship it to you for $499 or ftf for $475. Includes 2 ten round magazines, and 22 caliber barrel, plus bolt assembly to feed and eject 22LR to turn your HK91 or clone into a 22 semi auto - drop in kit - no tools required and no permanant change to your rifle. email me at mssgn @ hotmail.com (no spaces) if interested.

That's exactly what I thought when I saw this thread. But of course I would say that since I'm teetering on the edge of buying one to screw around with just for the heck of it.

[Groovy Mike]

Conversion kit is still for sale - $499 shipped or $475 face to face. I'd also consider swapping for a Saiga 12 or a NY legal AK.
