Ahh don't sweat it - the military don't use rimfire anyway!
Get a 10/22 and work it out from there. My wife and I started with identical rifles.
Mine ended up like this
1022 Snake Ruger Small by British Red, on Flickr
My wife's ended up like this
Dragunov Ruger small by British Red, on Flickr
They are fundamentally the same rifle, just different weights, barrels, stocks, triggers, recoil buffers etc.
Which bits are the same there BR?
