Meprolight Mepro GLS Reflex Sight for 40mm GLS (Illuminated Dot Reticle)

Engineered specifically for 40mm grenade launchers with Picatinny/Weaver rails, Meprolight's Mepro GLS Reflex Sight for 40mm GLS comes with several design features that help get you on-target including a 2 MOA impact point correction, and 180 MOA windage and 320 MOA elevation adjustment ranges. M203 ammunition has a tendency to drift sideways during flight, so the sight is pitched at a 2° angle relative to the rail to compensate this ballistic effect. A scale on the front riser represents the distance of impact in meters to aid in aiming.
