anyone have one that can give me some insight? I'm looking at all the different .22 tactical styles since the LGS just got in all the big ones, the M&P 15-22, the Colt Umarex 22, the remington 597 VTR (Which i was told is jam-tastic), and the Ruger SR-22, all of which are priced about the same in the $500 range. I thought of buying just a plain 10/22, but i don't really want to deal with customizing too much. any preferences or info? i read the multi-page thread on the M&P 15-22, but when i handled it, it felt kinda plasticky.
