I am pretty interested in the sight, but have a couple questions.. I am pretty new to the sport and am not too savy on what exactally this is.. Is it a magnified scope single dot type sight, or is there any kind of pins involved? I'm looking for somethign extendable and with some length like this one.. but wanting multi pins, with no magnification. Wanting it for 3d. Love the fact that it is silver, and not black or camo.
