Have you looked at Cmore? C-MORE Systems - Red Dot Sights
I stuck a polymer railway on my S&W. It works well and the price didn't sting too much either. Also fairly light @ 5 oz.
I previously a had a Burris Fast Fire 2 on it, but I found it too small and hard to pick up quickly. Good optic but it will work better on my carbine.

AWESOME, I couldn't tell if it was the kind he had, his allowed it to be put on in place of the rear sights rather than using my aftermarket rail system... but that looks close to it and that is just the right price!!!
Funny every one that I know who owns a sightmark says it is a good optic. Yeah you are not going to jump out of a helicopter and let it hit hard Abe still work like a eotech but it will take a ok beating and still hold zero. Every negative thing I have read on sightmark is about their night vision capable holographic one. I know guys that own both and they said they will save the money and get another sightmark. But to some they think it is all about the big name.
I will be putting a sightmark on my AR. Heck I have another cheap brand on my 308 and it works great.
