Primary Arms GLx Lower 1/3 Cowitness Micro Dot Riser Mount - Black

The Primary Arms GLx Lower 1/3 Micro Dot Riser is a cantilever riser for micro red dots, optimised for AR-style rifles. The cantilever moves the dot slightly forward, leaving room for a magnifier behind it.

It is machined from 6061-T6 aluminium, and two steel cross bolts clamp to the rail and act as recoil lugs alongside an integral lug. The manufacturer's stated optical centre height is 1.64 in (42 mm) without the spacer and 1.765 in (45 mm) with the included 0.125 in spacer. It fits the industry-standard footprint used by Primary Arms SLx micro dots (Aimpoint Micro). The centre height applies to Primary Arms SLx micro dots; other optics on the same footprint may differ.
