The Streamlight ProTac Rail Mount 1 Weapon Light is a versatile, great-value long-gun weapon light that ships complete with both a remote pressure switch and a tail switch. It produces 350 lumens and 12,000 candela (219m) on high with a CR123A cell, or 150 lumens and 4,950 candela (141m) on a AA, with a 40-lumen low running 14.5 hours on CR123A.
It's dual fuel — running a CR123A or a common AA battery, both supplied — with TEN-TAP programming (high/strobe, high only, or low/high), fitting Picatinny rails and M-LOK via the supplied adapter. 6000-series anodised aircraft aluminium, IPX7.

Yes — both a remote pressure switch and a push-button tail switch are in the box.
