Overview
The Barska Colorado CO11538 is a 3-9x40 rifle scope with a 30/30 reticle, 1 inch tube and 1/4 MOA click adjustments, built with fully coated optics on a waterproof, fogproof and shockproof housing. It sits parallax free at 100 yards, which suits standard hunting distances rather than long range precision work.
Reviewers have mounted this scope on rifles from .22 rimfire to .308 and 7mm-08 hunting calibers, and several report it holding zero through repeated firing. At this price point the glass is described as decent rather than exceptional, and at least one reviewer flagged reduced clarity specifically in low light.

Who it's for
Fits hunters and shooters who want a budget priced scope that holds zero on mid caliber rifles, including rimfire and standard deer rifle calibers. Less suited to anyone doing low light hunting where dawn or dusk clarity matters most, based on reviewer feedback.
What buyers say
