A look at the SIG Air ProForce M17 GBB Competition Package that is available at Evike.com... "The Competition package comes bundled with a SIG Sauer Airsoft Red Dot Reflex Pistol Sight. The reflex sight gives shooters a significant advantage over traditional iron sights by offering rapid sight acquisition and a more natural point of aim to get you on target faster.

This low profile 1x23mm reflex sight features a wide field of view and 3 MOA red dot. The manual brightness control, located on the front of the sight, has six illumination intensity settings making it easy to see the red dot in all lighting conditions. The sight features easy to use windage and elevation adjustments, and the lightweight aluminum housing and shock-proof design ensure durability."
