You probably shouldn't do what I did:
I bought a stainless mini 14 and proceeded to install a brass catcher, a flash suppressor, a tripod and a day/night scope, then I gave it to my uncle in Texas to hold for me so I wouldn't get in trouble for having it in the people's republik of Califorinia.
At the time they were a little weird about stuff that looks too much like a sniper rifle
Yeah I know it's a very small bore compared to real sniper rifles, but I'll be darned if it wouldn't have done the trick in a pinch.
