Top-tier optic in the budget-minded category! - Vism Magnification Scope

PRO's: Cast out of one solid piece of aluminum. This optic has a solid mounting system - Quick Detach (I've read others experienced rattle, but not the case here). Elevation and windage adjustments hold zero like they should (my experience is with 5.56/.223) and bore sighting it to my AR was a breeze. Zero has held spot on after 750+ rounds. Comes with back-up iron peep sight (fiber optic at that and have three positions you can move them to). The top of the housing has an RMR footprint for a RDS (I have a Vortex Venom on mine and love it).
Glass/lenses aren't bad for an optic in this price range (obviously not on par with Trijicon, EOtech, etc), but it's also 3-5x's cheaper. Nav light and green laser are a nice touch, even if just finnicky. Battery life is better than expected.

CON's: There's some blue LED wash going on at the higher settings. Nav light lacks brightness.
