Night Fision ORS Stealth Night Sights — Sig P320 Yellow Front

Night Fision's Optics Ready Stealth (ORS) night sights provide a self-illuminating tritium sight solution for Sig Sauer P-Series and P320 pistols with slide-mounted micro red dots. The set pairs a high-visibility yellow front dot with a black rear for straightforward sight alignment day or night. ORS sights are engineered to minimize obstruction of the optic window while still allowing three-dot alignment if a backup is needed.
