This product is installed on Picatinny rails. The KV-D2 Tactical swtich (in the kit)can be installed on picatinny rails and 1913 rails. The triangular area on the host can switch between visible laser and IR.
This laser sight is new in the original package. The batteries in the separate compartment on the back are no good. I’ll send some new ones with the sight so it will be ready to go. Please see the pictures.
