Really rugged - Lucid Optics P7 Weapons Optic, 4x Picatinny Rail Mount, P7 Reticle Waterproof

I bought this after doing a bunch of research - looking at units costing 3x as much. I like it. The guys (current active duty military) like it, and comparing it to the ACOG, it's tough to beat at the price. We beat on it pretty good, and aside from needing a battery to light the reticle, you can't get much better for the price. If you got the cash, go for an ACOG. But you won't be disappointed in this unit. Etched reticle still works without the battery, too. Just not as bright. I'm using it on a suppressed 300BLK SBR demo unit to show to local police. They like it, and have been beating on it pretty good without any issues.
