The Ultimate Combo Electrosight by Barska comes well equipped with an impressive array of features and accessories. A total of 4 items are included in this combo set, including a 1-3x30mm Illuminated Reticle Scope, a 1x20mm Green/Red Dot Sight, a GLX Green Laser with a built-in mount, and a FLX 300 Lumen LED Zoom Flashlight. The rails of the 1-3x30mm scope allow for multiple configurations of the included accessories. The 1-3x30 scope is perfect for zooming in on a target, while the 1x20 Green/Red Dot Sight functions well as a backup sight for quick target acquisition. The zoom focus capabilities of the FLX 300 Lumen Flashlight can either focus the beam of light on a specific spot, or widen the beam to illuminate a larger area. The GLX Green Laser provides a quick-targeting option and is visible during the day or in low light situations.
