Built like a tank - Crimson Trace 1x Reflex Sight HRO Integrated Pic Rail Mount

I picked up one of these that was on sale as a demo. I love it so far. It's mounting and frame are rock solid. I believe I could do push ups on my rifle balanced on this optic. The glass is crystal clear and the dot is bright. There is just a hair of starring but I think that's my eyes, not this optic. I usually use a prism, etched so I have high expectations when it comes to a clear view and reticle. I have this mounted on 450 Bushmaster Pistol build and although I haven't shot with it yet, I am confident that optic will stay put and hold zero based on the solid lock up with my picatinny rail. I would consider this a duty rated optic, ready for the desert, jungle, bush and is up for whatever you throw at it. I just wish it had a CQB reticle, like the k-offs.
