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.Features :Automatic Brightness AdjustmentQuick Release Side Accessible Battery DrawerD-shaped, Crystal-clear Glass LensAluminum Housing
