You guys gotta look at a CZ 452 for a 22LR, that things shoots lights out for the price point....
I think that Monkey Bomb has a CZ 22. Not sure which model though.
They make a 16" bbl CZ 452 22 LR.....
There is no reason to have a barrel over 16" in a 22LR, the powder is burned well before 16" and you actually lose velocity by going longer than that....
