I have one on my AR, but I have the Strike Fire. It's a decent optic with very good quality. My only dislike is the God-forsaken on-off switch. The Sparc has a similar power switch, if not identical. It can easily be bumped on anytime, but I notice it most when I'm putting my AR in a gun case. You won't notice it for some time, and the batteries can die. I strongly recommend keeping a spare.
