One day I'm gonna get a Ruger 10/22.
When that day comes I am going to use a military style sling, like on my M1A (it'll need swivels), buy a bunch of magazines for it and outfit it with a peep hole sight like those from Tech-Sight:
Why? So I can kinda-sorta practice shooting a platform similar to my main rifle, but with ammo that $20 get's me 500 shots instead of 20.
Of course this similarity thing goes all out the window if I mount an EOTech holographic sight on the M1A. I guess in that case I better get the 10/22 peep sight AND cheaper red-dot scope of some kind, too.
One other thing that would make my 10/22 expensive, maybe, iffn....
A suppressor. Go plink without ear protection.
