It's a buy - Primary Arms The SLx 1x MicroPrism Red Dot Sight

This is worth every penny. Lives up to all the reviews I've read a watched. Good form and function all around. And looks mint on my ar pistol! It's the hands down the best alternative to red dots if you have a touch of the 'tism. I'd buy it again and again. Don't waste time being disappointed by cheaper options, start here, stop here. I'd get the 3x and 5x if i was ever in the market.
