Ok, So I read the typical reviews / opinions on the web first, but you can't trust most of them... I'd like to outfit my future Ruger PC-9 Carbine with a Red Dot sight. Never used one, other than on a pellet gun, but it seems to make sense on the Carbine. I'm looking at the Burris Fast Fire...

Which "Red Dot" should I be looking at for my Saiga-12. It's going on a UTG short rail. I want something open, not cumbersome, and durable. The last 2 i went through both got mangled from the heavy buck shot I was shooting. My budget is below $200. Any input would be greatly appreciated, thanks.
