Whilst cruising around on Tumblr, I ran across this picture that labeled them as Mosin Nagants. Of course, the only thing about these that remotely could be MN-ish is the turn down bolt handle, but lots of old milsurps have this. The magazine is separate from the trigger guard, and they are sporting an AK underfolder stock. These are pretty sweet, but I cannot, for the life of me, determine what the original rifle was for these two. Any thoughts?

those look like mossberg bolt action shotguns with rifle front sights
They are Tula made bolt action rifles (TOZ-122) in custom stocks.
Strike the previous. They are actually TOZ-106 and are production guns 20 ga shotguns

They appear to be a mannlicher/carcano type of bolt. They look very similar, as well as the little of the receiver you can see.
