Hey man!

From the looks of it, should be a pretty simple process. Just fitting some sort of connector at the magazine where the CO2 input valve / puncturing is, and going with a line.

In your place, I would try a minimalist setup and try to hide it somewhere inside the stock. So a small 12g CO2 adapter + regulator, such as Wolverine's Wraith standalone version + Wolverine's BOLT On Tank regulator High Pressure version.

With that sort of setup you can even go a step further and separate the output valve part of the magazine from the bb feeding mechanism, getting the valve part fixed to the gun and implementing some mag sticks kind of system for the feeding, which can easily be 3d-printed.

It's quite some work, but with the right tools and knowledge should be relatively simple to achieve.

The safest bet is simply using .40g bbs, they work quite well with the setup.

It's an airgun type design so fitting an adjustable hop up will be quite hard, as it's quite different to both AEGs as GBBs hop units. Maybe a small chamber such as WE Makarov's can work (and that would allow for Maple Leaf GBB barrel and bucking, which are great), but you'll surely have to trim the chamber feed ramp and fine tune that a lot.

For a sniper build I'd go all-in, use the built-in CO2 regulator idea (nowadays, I'd probably choose a Mancraft setup) and definitely try to adapt some sort of regulable hop chamber.

The inner barrel goes all the way to front handguard retainer, or to put it in other words, the only part of the outer barrel that's not filled with inner is the one that's visible beyond the handguards. There's no chance of hitting the outer barrel, not even if you used ridiculously lightweight bbs.

Anyway, Trench Airsoft makes a hop up + bucking + barrel retrofit for this system, and that one goes all the way to the front sight. I don't know if it's adjustable (although their premium, 70% real custom build uses this system and claims to have an adjustable hop up, maybe you can ask them)


About the regulated CO2 idea, I believe the most viable option would be Mancraft U-shaped CO2 adaptor with expansion chamber and regulator hidden inside the rear part of the stock. Fix the gas valve part of a magazine to the gun, and run a line between the valve and the regulator through the stock. Then make some magic for the bb feeding part, I'd go with some DIY stick type magazines or adapt some from other guns.

Keep in mind these are just ideas, what I would do if I ever get into the project of building a sniper Mosin-Nagant. I'm not even sure if the regulator does fit, or how to tap the valve for the line, or how to actually build the stick type mags. So proceed at your own risk.
