With the Stainless version Marlins, a 4xsomething-mm Tasco is included, it' s pretty cheap, but for a .22, it' s fine, it holds zero (not that it' s getting kicked at all) and it focuses well. I forget the parallax setting on them, but I rarely miss with mine, getting 1.25-1.5" groups at 75-100yrds isn' t usually a problem with that glass on my marlin.

There are a ton of cheap little 4x glasses at wally world that work just fine for .22 shooting, and unless you' re wanting better than 100yrds (which the round isn' t really good for anyway), a 4x is more than enough. Tasco is crappy, but you don' t need a cadillac glass on a .22lr that you paid $110 for, there' s just no reason to put a $40 saddle on a $5 horse.
