Sorry, Its not a Tasco....It's a Bushnell "Trophy". I like it because the red dot has 2 sizes as well as crosshair and variable brightness. IIRC, it was around $100.
Less expensive Red Dot sites have a larger Dot which hides the target.
PS I keep all my PCPs full, this keeps the seals from drying out and shrinking. On the CO2 guns, the cartridges have a lubricant in them to keep the seals healthy, as long as you get crossman CO2 cartridges.
