Featuring a sliding rail block for precise positioning, the gunmetal gray PL-3 Valkyrie Weaponlight from Olight shines a powerful 1300-lumen beam and uses readily available CR123A batteries. The rail mount features an adjustable locating block for a customizable fit on a variety of rails. A robust locking device ensures secure attachment while allowing easy, one-handed mounting and dismounting. The light will remain stably mounted shot after shot.
