When used properly, firearm-mounted lasers can provide a real advantage to the shooter in terms of both accuracy and shot speed, and LaserMax’s Spartan SPS-R offers many useful features at an affordable price point. The Spartan’s Rail Vise Technology allows the unit to be mounted easily to a single slot of Picatinny-style rail, making it compatible with a vast assortment of platforms. Weighing a scant 0.6 ozs., the Spartan is fully windage and elevation adjustable, is programmable by the user to produce either a steady or pulsed beam, and features a small segment of rail along its bottom surface for the installation of ancillary accessories such as a weapon light or infrared laser. Also available with a green laser. Price: $100 (red), $150 (green). Contact: LaserMax, 3495 Winton Place, Rochester, NY 14623; (800) 527-3703; lasermax.com.
