CETME rear sight
Okay, CETME is not the "Top of the Line" .308, but I have one I am kinda stuck with.

Dern thing shoots to the right (even though I went the max amount available to align the sights).

I took a string from the front sight enclosure and ran it to the butt stock. The rear sight (welded to the receiver and non-adjustable) is not in line. It seems to be about 1/8" to 1/4" to the right.

Any suggestions on how to break the welds without ruining the receiver and rewelding it into the correct position?

Have you considered filing the rear sight? It sounds like you would have to open it up an awful lot though.

The rear sight has a "flip" arrangement for different ranges.
The 100m is a "V" sight, the 200m, 300m, and 400m are similar to the M-16 rear sight (an "O")
My thoughts are to "Dremel" the welds. After removing the sight, file the remaining weld marks on the receiver and re-weld with a wire feed welder.

My concern is warpage of the receiver (it is stamped metal).

Yeah that could be a serious problem. I haven't done it so I won't even attempt to advise you. Hopefully one of the other guys has some input.

If your tired of it, I'll pay the one way shipping fees to my door.

I thought about moving my rear sight, but sold it before I got the initiative to to so.

Dremel with a cut off wheel would remove it, then a few tack welds to put it back on. Be careful, and you wont overheat the receiver.

i used a cutoff wheel to remove my cetme rear sight,then die grinded/file,to prep the rear sight area.

i replaced my rear sight with a hk91/g3 sight and gives you windage & elevation adjusments.its the best 30bucks you'll spend on a cetme;)unless you want to scope it then throw a claw mount on it. this is the site i bought my hk sight from-

Uzi Parts - RTG International Surplus Gun Parts or

i used a tig welder,you have a mig right?

i wouldnt worry about warping,i would be more worried about blowing holes through it,find another scrap peice of metal w/same thickness to dial in your heat settings on your mig.

danf_fl 07-30-2012 02:13 PM

Yes, I've got a MIG wire feed.

The other option I have is to use JB-weld.

Would the operative words here be "Take your time" when doing it?

m72law 07-30-2012 02:18 PM

"Take your time" when doing it?

that might help that JB weld..remember that sight will draw up when heat is applied,clamp her down,& go for it!:D

I ordered some "practice" pieces from

I plan to do a trial run on a used rear sight to see if my skills are up to the task.
