While i love all the rugers i have . I wouldnt buy either of these 2 you mentioned.

Remember rugers mini 30,s uses a barrel made for american 30 cal(308 dia- not the plentyfull & cheap new& military surplus imported ammo(311 dia.)

Sks,s can be had new& used & for the price of one of thses you could get 2 of them And for for the price of a Ar/colt or something like it 3 & still get some change back
