Has anyone done or seen a comparison between these newer red dots? The Burris FastFire, Vortex, J Point, Leupold, etc. I have a FastFire 3 and a FastFire 2. The FF2 can't be manually changed for brightness (it automatically adjusts to ambient light) and it not bright enough for me, maybe a larger dot would help. I really like the FF3, it resides on my IZH35M bullseye pistol.
Does anyone know if the FF2 can be enhanced for a brighter dot? I can't get any response from Burris Customer Service to the question.
