The Night Fision Optic Plate + Backup Sight Combo (brand part no. SIG-OPBS-RMR-P320-YGZX) is a red dot mounting plate paired with a co-witnessing backup sight, not itself a light or laser, built from 17-4 stainless steel to the RMR/507C footprint for the Sig Sauer P320. Buying the plate and Night Fision’s premium co-witnessing sight together in one package saves a separate purchase while guaranteeing the two are matched for correct sight height.
