Can anyone suggest how I can adjust the cast on my factory stock?

I have a Kahn Arms Arthemis O/U, its pretty much the same as the Mossberg Maverick because they are made by Kahn Arms.

I have found multiple choices for LOP adjustments and intend can easily install one.
I've also found many sites selling parts to convert it to an adjustable comb but I don't really want to sink that much money into such a cheap gun.

What I'm wondering is if anyone knows where I could buy a shim to adjust the cast. Do they even sell one for this stock?
 
This isn't doable with the wood stock on your O/U shotgun due to its inherent design. In fact, other than the new Benelli O/U such type of adjustment (via a shim) won't be possible either with any other brand of O/U or SxS.

Normally, where deemed essential (and financially practical), the wood stock on a double gun could be bent to specs by a competent gunsmith. However, in the instance of a Khan, the expense involved may outweigh the cost of the firearm.
 
Being familiar with the shim system on Beretta semis I've never quite understood why the same concept couldn't be applied to an o/u. The shim simply moves the stock right or left in relationship to the stock bolt.

If only a minor adjustment is required the quick and cheap way to change the cast is to shave down one side of the stock to bring your eye more in line with the bore.

I tend to agree. May have to tweak the stock bolt over or make the hole for it a little oval too.

So you guys are suggesting I take the stock off and sand the wood where it meets the metal to change how it seats?

I'm assuming that you may not be familiar with the stockhead of double guns. Nevertheless, the above statements would still mean that such work will require a skilled smith or someone with requisite knowledge of fine woodworking (including appropriate measurements) to perform the delicate task.

Example - I once had the forend of a less expensive but otherwise nice shotgun shaped into a splinter. The task itself was very simple and straightforward and the smith had a lot of room to work with on that forend. Still cost me almost as much as I had paid for that shotgun.

I'm not suggesting that. I'm suggesting shaving the entire side of the stock to move your eye closer to the bore. No different than sanding the comb to lower the drop.
 
sorry guys, I thought this thing was a pump for some reason. I see now it is an O/U.
I have no suggestions beyond what the others said. It's a cheap gun. I wouldn't bother.

I dont think the OP is talking about cast on cast off. I is talking about the angle of the butt plate, degree of pitch

Actually I am talking about cast off.
I am planning to change the but plate so it seats better on my shoulder and gives me the correct length of pull but I still have the issue of being off center. I find myself actually burying my face into the stock and even tilting to gun to get on center.

As you can see from the pic the gun is actually turned a touch and my eye is still off to the side.
If I can't adjust the cast of the stock then I guess I'll have to have an adjustable comb installed. Would still be cheaper than a new gun.
 
Depending on how the wood fits into the receiver you may be able to add some type of wood filler or epoxy to the wood on the interface in such a way as to add the desired cast-off. Essentially the same effect as a shim. It would only take a few mm's thickness to move the cast. Nick Mackinson did something similar for me on a Beretta O/U to make a cast-off stock, cast on or more lefty friendly. You'd want some kind of barrier, grease? glad wrap? to prevent gluing the stock to the receiver in the forming process. Disclaimer- He's is a gun smith, I'm not, and I didn't observe the actual alchemy involved in the process. If it helps I can pull the stock of and add a pic of what the head of the stock looks like now

Much appreciate if you could post an image when you have a moment (pls PM me an idea of conversion cost involved at the time). I had some work done by Nick M in the past and it was very satisfactory.

A young acquaintance I had met last year eagerly presented himself with a 687 SP V at his graduation. At the time of purchase, I had cautioned him about buying that Beretta since he is left handed. He appeared skeptical and went ahead with the purchase anyway. A fix is needed now. :)
