LaserMax LMSG41151G Guide Rod Laser 5mW Green Laser with 520nM Wavelength & Made of Aluminum for Glock 20, 21, 41 Gen4

Presenting the LaserMax LMSG41151G Guide Rod Laser for Glock - a product that's robust, easy to install, and guarantees superior performance. This device not only meets but surpasses both Mil Spec and Homeland Security's rigorous durability tests. Withstand trials include drop tests, blowing sands, extreme temperatures and humidity, salt water fog, deep water immersion, and over 20,000 rounds of live fire.

The installation process is as simple as field-striping the weapon itself. Its pulsating laser beam ensures effortless muzzle awareness, making it a universally applicable tool that transcends language barriers. This laser can be reliably used outdoors from dusk to dawn, or constantly indoors.

All Guide Rod Lasers arrive pre-aligned from the factory for 20 yards. This guarantees their consistent alignment, eliminating the need for re-zeroing even after battery changes. Its unique positioning closest to the Glock's bore results in the most consistent relationship between your point of aim (poa) and point of impact (poi) for all shooting distances. The custom takedown lever controls the activation, designed to closely resemble the factory Glock take down lever, thus ensuring ambidextrous use.

This particular model emits a green laser and is custom made to fit Glock models 20/21/41 GEN4.
