Please note: Some aftermarket slides have a precise optic cut based on the curved edge/corner of Vortex Venom, one of the common slide manufacturers is PSA Dagger(with Doctor cut). ADE and other brand red dots do NOT have the same curve as Vortex Venom, therefore ADE RD3-006, 009, 012, 013 do NOT fit the aftermarket slide with CURVED vortex venom optic cut. ADE red dots with Doctor footprints only fit squared optic cuts that accept standard Doctor Footprints.
