I would imagine you could hold the Ranch Hand or similar type guns up to your cheek and acquire a more or less normal cheek weld, even though the stock isnt against your shoulder, and have decent results.
Ive done this with my AK's with side folders, and a couple of SMG's with the stocks collapsed, and they all shot quite well are reasonable distances.
You just get a cheek weld where you normally do with the stocked version or stock out, and the only thing missing, is shoulder contact.
