T.A.S. Glock Sight (green). This is a fiber optic sight, not a night sight. It is meant to take the place of both front and rear sights although some people leave the front sight on. I had it installed for one range visit on my Glock 22 before I sold the gun. It is basically brand new. It is an awesome sight, just no use for it now that I don't own a Glock anymore. $60 shipped via PayPal (my loss your gain) Thanks!!
