Reviews Description: Fixing the 'Quick Shot 30mm' red dot sight in place is a cinch, with two large bolts on the side, easily tightened using a coin in the slot. Gamo deserve credit for attention to detail here, as they even include their neatly designed arrestor block, to sit behind the sight on the rails, eliminating the chance of any creep at a stroke. Sighting in the red dot system is simple too, since there are only three controls to worry about. The two small covered turrets are the conventional windage and elevation adjusters, easily set via a small screwdriver. The large graduated knob on top of the unit is the rheostat and this houses a small disc type 2032, 3volt battery (supplied). The Rheostat allows for the usual 11 brightness settings, and the red dot itself shows as a floating image within the 30mm circular tube. The fact that the shotgun style front 'bead' is perfectly visible through the sight window just adds to the overall feel of this. - Magnification: 1X. - Field of view: 24.7 mts - Objective Diameter: 30mm - Eye Relief: unlimited - Movement windage: 40 MOA - Movement elevation: 40 MOA. - Click value: 50 moa @ 46.15 mts - Length: 100 MM. - Weight: 190 gr.
