There are few options unfortunately
There aren't as many stock options for mosins as there could be. The ones I know for sure about are the ATI stocks (plastic), and there is a company that makes wood sporter stocks and copies of military stocks out there (I lost the link). -EDIT : It is Boyds Gunstock Industries (

When I picked up my M44 I had just heard about the 'scout' rifle concept, and thought it was pretty neat. So, I picked up the stuff to do it- M44 scout mount, a Bushnell Trophy red-dot scope, and an ATI stock and bipod.
When I got that ATI stock I thought there must have been a mistake. It was abominable. The action couldn't be fit down into its seating, and there was a huge bow in the foreend of the stock. So, I sent that stock back and waited for a new one.
The new one arrived, and lo and behold; had the same problems. Exasperated, I trimmed out the barrel channel so the barrel could be put in without being pushed to the side by the stock, and spent a couple days fitting the action into the seating.
The rifle itself is in pretty poor shape, with a sewer-pipe bore, and it has never shot well at all.
After a lot of frustration I took off the scout scope and cut the stock down to just in front of the chamber. Accuracy improved a little after doing this, and at this point I'm treating that rifle as an accuracy test-bed.
With the ATI stock, recoil is quite a bit more manageable for me. The pad helps, the geometry helps, and making it butt-heavy seems to have helped a bit somehow. Cutting down the stock assured that the barrel is free to whip around and change geometry as it heats up. The 'Monte-Carlo' style cheekrest is somewhat a hindrance using the iron sights, as it is intended to raise your head for use with a scope, so be aware of that.
I would say in your case; keep the original stock (or, if it's an M44, send it to me!
) and drop the action into an aftermarket stock if that's what you want to do. You will spend some money, but the results are often quite good in terms of lightening the rifle and improving fit for sport use.
At this point, after I finish bedding and doing a trigger job, if my M44 carbine is accurate enough to do 6MOA with a 2x scout scope, I will be preserving it as my SHTF/oh snap! coyotes! gun. It is light, comes up to the shoulder nicely, and packs a punch.
