I'm looking for a glock 19 or glock 26, gen 3 or 4. This has the two dot reticle that is zeroed for 200 yards and 500 yards with .223 ammo. This has the quick throw lever and mounts higher on the gun for a lower cowitness. I bought it in August and had it mounted on my scar. Fired maybe 300 rounds with it mounted. I may be interested in other trades so don't be afraid to offer up something other than a glock. This is my first post but I am an established member of Spokaneguntrader.com and go by the same user name there so you can be assured I am not some scammer or flake.
