Primary arms 1x prism - Primary Arms The SLx 1x MicroPrism Red Dot Sight

An extremely nice and solidly built optic. I now own three of them 2 on ar15s and this latest one on a PSA AK. The optic is mounted on a midwest industries qd rail and it seems to be a really nice combo. Optic is clear, lightweight compared to other solutions and allows you to compensate for any offset between open sights and optic center, which is a huge advantage over other types of optics. I used to be concerned about durability of primary arms prisms but they are solid over the last couple of years. I expect this new ine will be the same.
