Up for sale is a Burris Fastfire 3 with a Burris glock rear site mount/base. This is the 3 moa (smaller dot) - has three brightness modes and an auto adjust mode. It's been installed (obviously) but I never shot with it or sighted in- so it's basically "like new in box" - includes box and tools and paperwork it came with. I paid $245 for the sight and $45 for the base. Base fits standard size glocks (currently on a glock 23) should fit everything except 10mm or 45acp models, and the 42/43 model.
Selling for $220
