I have this on my marlin 795 .22 The Green lens caps are relaxing. Came with rings. on the lowest settings at dusk you can shoot any critter hiding under fallen trees or in a shadow. I haven't noticed any parallax issues at 120 yards which I plink at regularly. Adjustable Ocular is useless on my short 22. I'm more than satisfied with Barska.
Pros: IR reticles(great dusk varmint huntin), good value
