Description
The Theta Optics 551 Red Dot Sight is built around an integrated 20mm Mount, which lets you install the Sight onto RIS/RAS Picatinny Rails by unscrewing the nut, placing the mount over the rail and tightening it once again. The sight is adjustable for Windage and Elevation, allowing you to correct for errors in BB flight path or alignment with the sight. Simply use a Flat Head Screwdriver to turn the appropriate dials, and align the Target Dot with your BB impact. Batteries are installed at the front of this sight by pulling up the lever, pulling away the Battery section, installing Batteries appropriately and re-securing the compartment. The rubber buttons on the back of the sight control the On/Off, Brightness and Colour function of the sight. The Up/Down arrows will adjust the brightness (and turn the sight on should it be off), the middle NV button will toggle reticule colour, and holding both Up/Down arrows for 5 seconds will turn the sight off.
No matter what platform of Airsoft replica you have, we can almost guarantee that the TO511 will look sweet sat on top of it. If you’re looking for a cost effective sight that won’t compromise on quality, then the Theta Optics TO511 is right where you want to be.
