The 15-22's an outstanding Plinker/Target/Varmint Rifle. Here's mine..... modded just a bit:
I've got it decked out like I want it, and it's my Bench-Shooter, obviously. I recently bought a Sig 522, so I can keep it Stock, and use it as a Standing Shooter. The only add-ons I have are the Vortex StrikeFire Green/Red Dot Scope, and the Pachmeyer Grip Sleeve.
Both guns have 25 Round Mags, and are extremely fun to shoot! Which do I like better? Both!
