XS Sight Systems RMR Minimalist Tritium Optic Plate Combo Features The XS Sight Systems Minimalist Optic Plate Combo takes the guesswork out of mounting an RMR footprint red dot on a Smith and Wesson M&P by pairing a purpose cut steel plate with a matched set of co-witness sights. The plate s 30 percent increase in thread engagement over typical mounting hardware helps keep the optic secured under recoil reducing the risk of a loosened or failed mount. A low co-witness height keeps the sight picture clear of unnecessary obstruction in the optic window so the shooter s view of the red dot stays unobstructed. BlackNitride surface treatment on the steel parts resists corrosion better than an untreated finish standing up to sweat moisture and daily carry. Completing the combo is a set of XS night sights built around steel bodies with tritium inserts front and rear giving the shooter a visible backup aiming reference day or night. Should the red dot ever fail or run out of battery these fixed sights remain usable without requiring the optic to be removed. Built specifically to fit the Smith and Wesson M&P the combo installs as a matched set rather than requiring separate sourcing of sights and a mounting plate. This XS Sight Systems Minimalist Optic Plate Combo is available for sale at GrabAGun for M&P owners looking to add a reliable RMR footprint optic setup in one purchase.
