The LaserMax LMSG517 Red Guide Rod Laser for Glock 17 Gen5 Black delivers a purpose-built enhancement for Glock 17 Gen5, Glock 17 MOS Gen5, and Glock 34 MOS Gen5 pistols by replacing the factory spring guide assembly with a high-intensity red laser sighting system designed for rapid target acquisition. This rugged, precision-built guide rod assembly integrates aircraft-grade components and is user installable without gunsmithing or special tools, enabling a clean, streamlined upgrade that preserves the pistols balance and reliability. Its 5mW red laser at 635nm projects a 0.63-inch dot at 20 yards and provides a practical 50-meter visual range for fast, accurate aiming in dynamic shooting scenarios. A straightforward On/Off switch keeps control simple, while the units automatic 10-minute time-out helps prevent inadvertent battery drain. Weighing only 0.76 oz and finished in durable Black, the LMS-G5-17 maintains a low-profile footprint that suits carry, range, and competition use without compromising the firearms ergonomics. With this guide rod laser, shooters gain an immediate advantage in low-light conditions and high-stakes environments through quicker sight alignment and more consistent shot placement.
