Vortex defender xl green dot 3 moa - Vortex Defender-XL 1x 25 mm Reflex Micro Green Dot Sight

I bought the Vortex Defender XL to go on a pistol that had a Deltapoint adapter plate for . Green dot is excellent . Shake awake and auto shut off is a must . Large window is fantastic ( a little taller but not as wide as Holosun 507 Comp ) . Top install battery tray design is great and side brightness buttons are large and tactile . Comes with a variety of screws depending on the brand of pistol you are installing on . Also comes with a picatinny mount for use on a railed gun . Even comes with a Glock MOS plate and screws but I don’t know anyone who uses those . The deck height is about the same as a Leupold Deltapoint so you need tall iron sights if you want to cowitness at all . Front window sits a little forward compared to Deltapoint so be aware about how much room you have above ejection port , it varies depending on brand of pistol . Good price , cheaper than Leupold or Holosun . The only negative thing I can say is the adjustment tool it comes with is terrible but no big deal , I’ll use my Holosun tool .
