This is the most bang for the buck scope you will ever find. - CenterPoint 4x32mm Rifle Scope

This scope came with my Crossman Vantage MP air rifle. At first, I didn't have high expectations of it because I was of the mindset that any scope that comes with a low tier air rifle can't be that good, but I was pleasantly surprised at how good the glass is. The reticle is etched nice and dark on surprisingly clear glass. It's super light weight owing to the fact it's non-adjustable. The large aperture lets in a lot of light even during twilight hours. The turret adjustments are 1/4 moa at 100 yards which is more accurate than a pneumatic air rifle can ever achieve at 100 yards anyway. I would put this on higher end air rifles. The only real con is eye-relief. I have the rear scope ring slammed up against the elevation turret and still my sight picture could be bigger, but for $45.00, it's hard to beat. As an added bonus, the scope caps are clear so when you need to take that shot quickly, there's no fumbling to take it off.
