I know that the rail system that Kushnapup recommends is the one from ULTIMAK.  They make good stuff, as I have the gas return tube with rails built in on an AK of mine.

I am looking for ideas, both products and how you mounted them, for rail systems on the Kushnapup.  My main concern is for adding a sight system to the Kushnapup via the rail system.

I don't like the ULTIMAK solution this time around because I have one of the older Saiga 12s that have fixed sights, and I don't want to ground the sights down nor drill / tap my gas return tube, just in case I want to return it back to a regular stock.

So if anyone has alternate ideas please post a link to the product here to make it easier to find, and how you mounted it as I am sure not all of the products are going to be designed for the Kushnapup and will require some modifications.

Thanks in advanced for your for your input!

Ill just repost it.

I had  a Mosin Nagat rail set that i bought from Cheaper Than Dirt.com  which I stuck on the top of my KushnapupSaiga12.  

I like the look, but am not really satisfied with the stability.  I am doubtful that it will hold zero as i have it now.

What i did:
I removed the factory front site from the gas block.  You can do this quite easily by taking to block off the gun and flipping it upside down.  There will be a hole in the bottom of the block.  Look through the hole you will see the gas hole and through that you will see the underside of the front site.  Just insert a punch through the holes you just looked through and wack it with a mallet.  Now you have a hole from the gas piston chamber to the top of your gas block.  Get you a 6-32 x 1 1/4
screw.  Now remember, the gas piston/puck has to be able to slide in that chamber with out rubbing on the screwhead! Soooo you will most likely have to take a grinder to the screw head to make it smaller and a drill to the underside of the hole where the front site was located just to make the underside of the hole a bit more cone shaped.  With a few nilon spacers in place i droped the rail set on the screw protruding from the old site hole and the nut fit perfectly in the hole provided.

Now the reason i am not happy is because it only has 1 point of attachment, when a figure out a second poi t i will update this post... Sad

Hey Papa, I havn't had a chance to work on mine yet. How far do you think you had to add to the buttstock pad to keep the tangs? If I remember right it's like an inch or a little more.

Went to the range Smiley   Was just shooting birdshot though...should have brought out some buckshot Sad

The gun/stock shot flawlessly!

The rail system i had installed didnt fare so well Sad  The height and positioning was perfect but the single attachment point didnt work...back to the drawing board...

I bought the Ulitmak Gas Rail when I bought my Saiga, back in '10 (same day I paid for the Kushnapup).

Unfortunately I didn't install it, I just waited for the Kush. Now it's at the gunsmith. Once I get it installed, I plan on using a Aimpoint T1 on a riser.

I made my own bracket out of aluminum in front of the gas block.  The first one looks better, but is too low for a good sight picture.  The second one, I used a higher rail mount and the sight picture and cheek weld are perfect.  Now I just have to fix the tang problem.

Can you post some close-up pics of the brackets you made and how you attached them? I'm getting ready to mount an optic and might use your idea. Thanks.

Thanks for the welcome.  Here is a picture of the bracket ( the two in back were prototypes in aluminum and steel).  Next is the bracket in place with a short rail on it.  And last is a Walther red dot/ mount on top of a high rail to get it higher for a good cheek weld. It may need more reinforcement, but it seems very sturdy and a few hundred rounds will tell.  I'm sure the ultimak is the way to go, but for now I'll try this.

First find a piece of scrap aluminum then cut, grind and measure. This is my prototype for the Kushy .308. I just lined it up with nails for now.
