Holographic sight for home defense shotgun. - Vortex Razor AMG UH-1 Gen II Holographic Sight

I bought this sight for my IWI Tavor TS12. I'm using a UTG Pro milspec carry handle with a Yankee Hill flip up front sight as a back up sight setup. The AMG UH-1 is built like a tank..much like my EOTec's.BUT...always a but, I have a problem with the position of the lenses in the sight. They seem to me... very exposed to damage by being so close to the edge of the frame of the sight.My EOTec's have a protective cover that offer some protection to the lenses. I do like the quick detach rail mount. I do like the easy battery access. The controls are EASY to manipulate. Unlike my EOTec's...you don't feel like your about to break your fingers trying to hit the adjustment sweet spot. The retical is a bit more refined than the retical on my EOTec's. It does actually seem more crisp to my old eyes. The last BUT I have with this particular sight is the weight. It's a bit heavy for a sight that's perched out on the end of an already almost 13 pound shotgun...that said...being a bullpup..it balances strangely well. I've also used this sight on one of my AR's...it's very much at home there. If I would have to rate this AMG UH-1 over my EOTec's...I would say the lenses are better protected on the EOTec...but the retical is much better in the AMG UH-1.
