The RMSd is a compact and durable pistol red dot sight machined from aerospace-grade aluminum to withstand recoil while remaining lightweight. Its discreet size allows for easy mounting and automatic brightness adjustment ensures clear targeting in any environment. A quick-release side-accessible battery drawer facilitates battery changes without dismounting the sight. The low-profile design enables co-witnessing with standard sights on many Glock models eliminating the need for suppressor height sights.
