Who has a type-56 with the West Coast rail still intact.(K-Sports Hunter, etc.)

[Greatguns]

As some already know, I recently acquired a K-Sports Hunter with the West Coast rail on it and think I may have figured out how to modify an existing AK mount to work on it with no mods to the rifle other than a slight amount of trim to the stock where it is already cut into for fit.

Anybody interested??

[CARBINE]

a slight amount of trim to the stock where it is already cut into for fit.

I have one, but you lost me at slight stock modification, others have modified the navy arms scope mounts to fit I have seen, but even those are hard to come by and expensive, someone should just machine a new one!!!

[Power Surge]

I have another idea.... how about just machining an adapter? Something like a rail that slips over the west coast rail and then allows a more commonly available rail to then attach to it?

[Greatguns]

I'm just referring to trimming a little bit of the wood stock for fit after the mount is installed onto the rail. The nominal gap between the rail and the wood stock is about 1/8", but given variances it may be necessary to shave a tad off the stock for fit.

You won't have to do anything to the rail or the receiver.

Yeah, I still wouldn't shave the stock even a little. Just me.

I'm talking filing a few .001" not really like cutting more off the already cut stock. Just enough to make sure everything seats properly. Basically I'm stating that as a disclaimer that it may have to be done.

Anyway, I'm going to order the scope mount in question that I am thinking of using and will work on the mods. I will post up pics as I go and we'll see how it works out.

Then take it off the bottom of the mount.   

[Greatguns]

You guys are impossible. 

Anyway, I guess one can do it whichever way they want. Me, I'd file the wood a tad. If you want to file the metal then you are at your liberty to do so.

Anyway, I got the mount ordered. FYI, I am using the ProMag AK mount that has 3 set screws on the side as opposed to the QD type or the screws that come up from the bottom. I will be able to slide a steel spacer along the dovetail of the rail to fill  in the gap to make it tight then the set screws will hold it in place. I will cut the side of the mount down and re-weld it to height and whatever other modifications I may need to do. Will probably have to cut the rail mount section down as well on the mount itself.

I have thought about this mount for a long time and here is what I came up with. There are many dovetail to weaver adapters out there and I have checked out several and came up with this one. These things are pretty cheap.

Here is the pics if the link dies

Note the allen screws holding one side of the dove tail to the adapter.


Remove the two screws and the dove tail side. file down the mating surfaces enough to tighten the tolerance on the dovetail. This mount is equipped with a set screw in the center. This screw will line up with one of the divets in the K-Sports rail and tighten as necessary. Filing the bottom of the mount or releaving the stock maybe necessary I don't know. Mounting to the rail is done.
Next remove the lugs on the weaver rail (top pic) with any means available (mill, end mill in a dril press, file or sand paper on a piece of glass). This mount is thick enough to weld a piece of angle to it or drill and tap several holes along the side and mount the angle that way.

You can get real small quantities of aluminum angle from Aircraft Spruce and Specialty.  2 x 2 x 1/8 or 2-1/2 x 2-1/2 x 1/8 is available.

You will still have to mount a weaver rail to the top of the angle. Bulk rail is on Evil bay for cheap. Cut to fit drill and tap.

A little bit of your imagination is necessary and a drill press would make it easier. but not required.

Yeah Joe, that dovetail to picatinney rail adapter was the first thing I looked at. The thing that killed it for me was dealing with the screws that lock the dovetail down. Might be difficult to get to once the rest of the mount is welded together. Didn't care for the amount of welding or D&T either.

I'm going to start with this;


I will make a spacer to fill in the gap on the rail mounting portion then simply cut and re-weld the the picatinney rail portion to the correct height. I may end up cutting the back of the mounting area off in the back along the rear most set screw or right behind it. Won't know exactly where until it arrives and is fitted.

My other option is to take the top portion of my AK scope mount and weld it to the adapter mount that you mentioned, but I'd still have the issue of getting to the mounting screws which would either be facing down into the stock or up inside the rail bracing which could make it difficult to get to. I guess I could D&T the bracing onto the adapter, but then one wonders if it will hold. Screws being a potential weak link and coming loose and all from recoil.

Once you set the clearance the screws never need to be removed. The screws don't clamp the dovetail. The mount has to slide. The center bolt locks the mount to the rail. The amount of welding is the same on both Ideas if you choose to weld.

Hmmm, I see your point. I think maybe we're coming to the same point via 2 different approaches. We'll see how it goes. If all else fails I'll just drill out the rivets, remove the rail, then order a Choate  or ProMag SKS mount, lol. Or plug the holes like on the ex-sniper Mosins, lol.

[Greatguns]

Well Joe, I got the AK mount and after playing around with it I decided to combine our ideas. I am going to cut down and use the AK mount top portion, but I ordered the 11mm to 20mm adapter rail you suggested and am going to work with that instead of the spacer idea. This way I can D&T into the adapter and actually may not have any welding to do. Price of parts vs price of welding labor offsets.
It also dawned on me that if I make sure I can get the receiver cover off with the mount installed I can get to the dovetail clamp screws from the top with a hex key from across the top of the receiver so it won't be so hard after all. And, I can still utilize the set screw into the divots to further lock it into place. Should actually be minimal work.

Hey GG...  Thats the adapter I was telling you about.   Used it to make two scope mounts to the factory vostok rail.

GM has one of my contraptions.

Ah, I guess it just didn't click that that was the adapter you were referring to.

Hey GG, did you get this project completed? I'm curious because I have one of the West Coast Rail SKSs. (or is it SKS', SKS's?...whatever )

No I didn't FC. Got too many irons in the fire and decided it wasn't worth the effort for me to complete. I ended up selling the rifle to a kid who was hot for an SKS. He works at AK-Builder and is a machinist and said he was going to make something up for it. I do still have the dovetail to picatinney rail adapter if you want it to try one on your own. Basically you'll need to cut the rail off and either D&T or weld a piece of angled aluminum to it then mount a rail on that for the scope.
PM me if you want the adapter rail, $10 shipped and it's yours.
