LaserMax Green Guide Rod Laser for Glock 22/31/35 Gen 4, Black - LMSG422G

This guide rod laser integrates completely into your Glock's internal structure, allowing you to keep your preferred holster and tactical accessories unchanged. The 5mW green laser (520nm wavelength) projects a 0.63" dot at 20 yards with an effective range of 50 meters, and installation requires only field-stripping your firearm. Built to exceed Mil-Spec and Homeland Security durability standards including drop tests, sand, temperature extremes, and 20,000+ rounds of live fire.
