I recently purchased a Vortex Sparc AR. It is basically brand new, but am selling as used because I opened the package and attached the lower 1/3 riser and mounted it on a rifle.
The optic itself is built like a tank and it looks to be one tough optic. This was my first foray into "mini" red dot sights and the combination of the small tube with my astigmatism just isn't going to work for me so I am going to let it go. Comes with all parts, box, and paperwork.
