unit31 0 Posted December 13, 2010 Report Share Posted December 13, 2010 Hey guys, I was thinking about adding some weld-on HK sights to my s12. My question is, is it as simple as just welding the sights to the gas block? Or will the high temps damage the block if I'm not careful? I have zero experience welding but I don't know if I can get away with just finding someone who can or if I should find a gunsmith who is willing to weld. Quote Link to post Share on other sites
Mullet Man 2,114 Posted December 13, 2010 Report Share Posted December 13, 2010 My 2¢ I would find someone who is skilled at welding, whether it be a smith or not. Distortion can occur, annealing the gas plug threads can happen. I have a welder and limited skills on projects but its not something i would attempt myself. Plus TIG welding or Silver Soldering would be the best options (i would think) and they are a skilled process/craft to master. Especially when going for a good finished product that you'd want to be visually pleasing. Quote Link to post Share on other sites
TonyRumore 1,332 Posted December 13, 2010 Report Share Posted December 13, 2010 I have had quite a few requests for replacement gas blocks due to screwups welding the front sight on. Tony Quote Link to post Share on other sites

justinmcmillion 77 Posted December 14, 2010 Report Share Posted December 14, 2010 I silver soldiered mine - no issues, just make sure you dont get silver solder in you gb threads I welded the rear one on I can post pics if needed or you can go to my youtube and check it out in several videos http://www.youtube.com/justinmcmillion Quote Link to post Share on other sites

cvhanh20 1,052 Posted December 15, 2010 Report Share Posted December 15, 2010 Nuff said...rail mounted sights it is! Thanks for the advice. Our new Titan and Nemesis rail system, covers this issue, giving you a longer line of sight than you can achieve with weld on sights, plus a platform for many types of low profile co-witness optics and provides the hinging system for those wanting their dust cover attached to the rail. Keep a look out more info coming soon. These new rails system will offer options never seen before for Saiga 12. 1 Quote Link to post Share on other sites

Looks like it comes to mid dust cover? Beautiful design btw Im not sure what weld on sights you are referring to but mine are welded to the far rear of the dust cover and on the far front of the gas block. If I wanted a "tactical" s-12 this would be a good choice to replace the factory sights, I use to have one of your rails on mine before I shortened the gas system, great product. Its now on my buddies s-12 as seen in the video Quote Link to post Share on other sites
YOT 3,743 Posted December 16, 2010 Report Share Posted December 16, 2010 Has anyone ever tried fixing the weld-on sights to the gas block with JBweld? Just wondering. Quote Link to post Share on other sites

Its now on my buddies s-12 as seen in the video Thanks for the kind words. The rail I'm referring to is our new line up, TITAN, and the NEMESIS. They are full length rail systems, the NEMESIS actually over hangs the dust cover giving 3/4" more line of sight than you can achieve with weld ons. Once I post the full prototypes everyone will see and understand. Quote Link to post Share on other sites
RABIDFOX50 6 Posted December 16, 2010 Report Share Posted December 16, 2010 Cameron's CHAOS extended quad rails with the HK type sights are what I would suggest if you do not go the weld on route. It's an outstanding system and I love mine. Quote Link to post Share on other sites
skiboatsp 111 Posted December 16, 2010 Report Share Posted December 16, 2010 If you go the welding route be sure to use someone who has very good welding skills and someone who has installed them before. There are many tricks to help with the job. Or you could just eyef*#^k them on Quote Link to post Share on other sites
justinmcmillion 77 Posted December 16, 2010 Report Share Posted December 16, 2010 Another good thing about the chaos is that your rear sight isnt mounted on your dust cover, which for a shotgun this doesnt really matter unless your shooting slugs I welded/silver soldiered mine on and never really sighted them in... I always hit where im shooting, but once again its a shotgun... I went with the weld on sights because I wanted a light weight sbs, but the factory sights just didnt do it for me, for this particular gun Im very happy with the weld ons and love the h&k front sight Quote Link to post Share on other sites
mark4567 4 Posted January 19, 2011 Report Share Posted January 19, 2011 Hi guys first time posting. I realy like the look of the HK sights. I have TIG and MIG at home and can weld well. How do you align the sights before welding? Just eyeball them or is there a trick to it? Any help would be great!! Mark Quote Link to post Share on other sites

How do you align the sights before welding? Just eyeball them or is there a trick to it? Any help would be great!! Mark I align rear with sides of reciever then use a bore lazer for front. Rosette weld rear then check alignment, then tack front, recheck alignment. My post above is when Tony in a previous post, about this said he just eyef@#k's his on.

mark4567 4 Posted January 19, 2011 Report Share Posted January 19, 2011 Do you remove the front block to weld the sight? Or use a heat sink and weld the sight on with the block in place?? Quote Link to post Share on other sites

Leave block on gun for proper alignment Heat sink is an excellent idea!! I use them all the time. Also move front sight back so heat is not concentrated on the gas plug threads....about 1/2" Edited January 20, 2011 by saigatechusa Quote Link to post Share on other sites
Parson Julabee Jones 32 Posted January 19, 2011 Report Share Posted January 19, 2011 (edited) I recently asked the gunsmith at our local Gander Mountain about putting front and rear sights on my Benelli M1/Super 90. He said he would drill and tap the receiver for the rear sight....but that for the front, he had found, many years ago, an adhesive that holds the front sight just beautifully, and had never had one come loose. While he didn't mention the name of the adhesive, he did say 'surface prepartion' and 'getting it straight' were the critical issues, implying of course, that I couldn't do it myself (as if I'd try).

But gluing a HK sight right to the hottest part (gas block) would probably cook the glue. Quote Link to post Share on other sites

If you check my digital S-12 build you'll see that it was eyefucked first and measured after as my friend felt the need to check how accurate I was... I can live with being a hundreth off on a shotgun with a adjustable rear. Quote Link to post Share on other sites

I guess no one cares about quaility. I personally build all mine as if I were building them for myself. Which they are for myself.

Not trying to be argumentitive here but... 3/32" = 0.09375" My variance by eye was 1/100" or 0.01" I believe you were thinking of a tenth. Quote Link to post Share on other sites
mark4567 4 Posted January 21, 2011 Report Share Posted January 21, 2011 So what you guys are saying is its a shotgun not a snipers rifle. Just eyeball it and close enough! Quote Link to post Share on other sites
Nailbomb 10,221 Posted January 21, 2011 Report Share Posted January 21, 2011 So what you guys are saying is its a shotgun not a snipers rifle. Just eyeball it and close enough! Basicly. your going to mount the rear on a dust cover that if you do nothing to will move around anyway. still no reason to not get it as close as you can. Quote Link to post Share on other sites
mark4567 4 Posted January 21, 2011 Report Share Posted January 21, 2011 Ohh I'm going to get as close as I can. I planned on when I stick it in the bridgeport to mill off the front sight, I would crank it over to the dust cover and mark it. So I have a mark to weld at. Quote Link to post Share on other sites
