Good but needs more.... - Primary Arms SLx Micro Red Dot Sight

I like the dot, it's small and streamlined and works(I think) I installed it on my flattop AR-15, annnd well I needed the top of the rifle to be almost at the top of my head to see anything, that or if shouldering rifle properly my face would be so crunched up it's painful. I highly recomend getting a riser mount like I just had to order. However for a really sloped down stock like on an HK USC or MP5, it might work properly.
