Atlas Custom Works Unit Lite Mount for RMR Optics, Black

Get your RMR closer to your eye line. This Atlas Custom Works Unit Lite Mount is a low-profile riser for RMR-style red dot optics, machined from aluminum and anodized black. Bolt it to any 1913 Picatinny rail, and your optic sits higher than a flat mount would put it — enough to keep your cheek from fighting the stock.

Why it matters. A lower optic means a higher head position, which translates to faster target acquisition, better situational awareness, and less neck fatigue when you're on the field all day. The RMR's compact footprint pairs well with this approach, but you still need a rail that has the room for it — mount position is a choice, not an afterthought. The mount is cut specifically for RMR-type optics and won't take other red dot form factors.

What you need. Your RMR red dot isn't included, along with mounting hardware. The riser attaches to any standard Picatinny rail on rifle or carbine platforms. If you're building around this mount, plan your optic and rail placement together so the sight picture works with your stock.
