I got couple questions about Swapping the wood stock for Plastic HK one.

[mity2]

Would this fit my Cetme?

And this is the pin I need?

Do I need anything else for this conversion to work?


two more questions.
is this an early triple support or later tripple suppport?

I'm going to remove this Century "Loudner" with original style hider. Where would be the good place to get them?


Thanks in advance

[HKILLER]

1=yes that stock set will fit, with trimming of the nylon oring at the front of the recoil spring.

2=yes thats the pin

3=as far as the front sight question are you talking about a cetme front sight? or a g3 front sight?

4=on the flash hider make sure u get a us made one to comply with the law, hkpart.net has them

Thanks for the quick reply.

Yes, triple support is for Cetme.
Mine, I belive is canted, but I can't adjust front sight, because it appears as if front sight post is soldered in by goons at Century:rolleyes:

So I'm going to atempt to move the post, but I like to have back up if i can't...

[Evilblackgunsrfun]

use a small butane torch to heat and melt the solder ,clean up the threads,should be easy, the solder should be kinda soft.
and do like i did, order the cheaperthendirt stock set, use the backing plate and spring assembly with a much better shape od green stock set from robert rtg, those g3 sets from ctd are pretty worn ,mainly the forearm, roberts stuff is just clean with a household cleaner and install ,and you end up with a much nicer looking rifle, unless your going for the used and well handled battle rifle look

[holescreek]

That front sight post doesn't look soldered into me, just excessive paint build up sprayed over cosmoline.

You were right. I think it was powder coat that looked like solder bubble.
I made the little sight adjustment tool(see pic), and was able to move it

Sight tool I made from some old rusty screw bit

I personaly don't think this is going to adjust enough, since my POA is about 7inches off to left at 25yds. But I'm hoping for the best.

In answer to your question about early or late style triple frame, you have the late style, machined triple frame. The earlier models were cast, and yet an earlier Modelo B style had a triple frame that is a cross between the current Hk blade style and the CETME style.

that suxs mity2 i have the same problem with my cai made cetme when i installed the g3 rear sight i had that sucker as square as i could but at 100 yards i was shooting a foot to the left i had to move the rear sight base of to the right looks funny but now she shoots like a dream. i really dont think its the front sights, i think its the receiver. just my 2cents.

I think your right about the receiver being off. I am getting my G3 kit almost to the point of welding and am having a tuff time on the rear sight. It lines up perfect with the center of the receiver, but the front sight looks like it has about a 32nd of a lean to it.
Sometimes more or sometimes less...... depending on how long I look at it.:crazyeyes:
I am using a barreled trunnion from the kit so I don't think the front sight is canted.
I'm leaving it go and hoping for the best, I can't do any more than what I have.

[SteelCore]

1. Yes
2. Yes
3. newer style.

on #1, you will have to take your CETME guide spring retainer off and switch it with the G3 one, or if the G3 one is plastic, you will need to reduce its external diameter just a smidge to get it to fit into the CETME carrier.

How can a receiver be the problem? The receiver is the only thing that can't be wrong.

Somewhere here Bladeworks has a thread where he talks about stretching a string from the front to the rear sight and looking along the string at the top of the receiver to determine how far of the triple frame is canted.

[HKILLER]

the reason i say that is because the sight base would not sit flush on the receiver where it was close to being flush it was off to one side, and i tried the string method it looks straight.

[Steve68]

I had the same issue with my sights being off about 8 inches. the front sight post is off set and believe it or not you can zero it. Someone posted the mechanical drawing (side view) of the front site, and you can get a better understanding of how it works.

[Steve68]

Here is the pic Jsquared posted. Turning the site adjusts windage and elevation at the same time. Also keep in mind that if you change the rear sight on your cetme to a g3 sight you will have to center your front sight or your windage adjustment on the new g3 sight will end up way off to one side.

Hkiller, make sure your front sight is centered before you adjust the windage on your g3 site. (If you still have a cetme front sight)

[HKILLER]

yeah the front sight is good and centered its welded and i shoots good now so what heck.

[Steve68]

How far is the windage on your rear sight?

[Lalvis]

Well I know my triple frame was canted! I have a CAI ss cast receiver, so I know it was not the receiver or the rear sight.
I was 6 inches off to the right at 25 yards!!! Had to remove the sling bolt, heat and cant it back to the left then check with a laser bore sight. Then install a new sling bolt. :g3:

I was thinking of same thing. Reciever is only thing thats constant here(Mine is Stainless steel cast model), unless CAI's reciever mold itself was off in first place(in which case, every CAI Cetme would be off - Wait! Hummm.. may be:rolleyes:)


Now, I haven't built Cetme pattern rifle before, nor I fully understand how one gets put together, but could barrel itself (or barrel to trunnion) may be welded wrong?

Anyway, Since my weapon's POI it about 6~8" off to the left of POA at 50yds with front sight post set on straight, provided that the everything else are correct and in spec(rear sight base, or projectile hitting Loudner on its way out), my triple support should be canted to the right to variying degree, correct?

So looking at the weapon from front, I turn front triple the clockwise(after removing eyebolt, heat the triple?

So when I do this, where on the triple do I heat after I remove the eyebolt? I'm thinking as indicated by the red line below

[bladeworks123]

If you are building on a stamped receiver, the receiver can be off after welding and the trunnion can also be cocked a little one way or another when built if the receiver was not almost press fit tight around the trunnion. It's relatively easy to get them out of line by a mere 1/8 of an inch. Even on a cast receiver. It's important when welding the trunnion that you tack both sides first before welding. I have had them pull almost an eighth of an inch. Tack the trunnion to the rails first, tack the tops each side and the bottom. You can use the string method, or ceck them from side to side on a flat surface. I will do a post on how I try to keep them straight. So far I have been pretty successful. If they are not too bad, on a stamped receiver, (not cast) you can actually bend them sligthly in a press with the right jigs. We used to find MP5's that would be bent just from being rolled over in training. 1/8 of an inch out of alignment on a barrel is just the same as moving your front sight from one side to the other, full adjustment, or your rear sight all the way to the left or right. Close to 24 inches at 100 yards.

[bladeworks123]

In your example, yes. Looking from the front, your triple frame would need to rotate clockwise. If you are impacting to the left, you need to move your front sight post left to bring your shot group right. It would be real helpful for you to know how much you need to rotate it. Get yourself a better target and find out exactly how far off you are. You can also trim the paddle on your rear sight and move it to one side or the other also, to get yourself a little more adjustment.

[Lalvis]

Yep thats what I did. Bullets going to the right... move sight to the left as you look form the stock to the front sight. And yes you are correct with the pic/red out line. But before you mess up the finish with the heat-CHECK THAT THE FRONT SIGHT IS CANTED. If you start to hunt and peck with the fixes you will be very lite in the wallet. Fixing the fix is a morale dumper. I know this from my past fix it. Had a bolt jamming. I thought it was the ejector. Now it won't eject at all!:icon_confused: Found out it was the recoil spring rod was bent.:1087: It all worked out for the best, I found a H&k 91 FCG complete for $70.00 on gun broker.:icon_biggrin: It only cost me $10.00 for a new ejector plus $6.00 shipping to fix the cetme FCG:wink:

[mity2]

Unlike my old PSL(which front sight base was visibly canted A LOT) if this is canted, it's not easily seen. Group at 50yds were consistant, just off to left 6~8". Now that got my front sight to move, and made the tool to adjust front sight, I'm going back out to try it again.
I really don't want to screw up the finish...

Now here is the question that many people with canted front triple have asked, but seems like noone have decimate answer to.

How do you check to see if front triple is canted or not? Or how much it's canted?

[Lalvis]

If you have a sight jig your all set. If- then I used a laser bore sight. I checked after I moved it and you can not tell by eye that it was moved. Does not look canted or anything. :America:
