I'm sure this will sound stupid, I just bought a rifle with a Tasco red dot scope on it and have no idea how to activate the scope. Any help would greatly be appreciated. Thanks
No, that doesn't sound stupid. It's always a good idea to get all the information before using firearms and their accessories, and I'm happy to help:
The large knob on top of the scope is the rheostat, which is used to turn on the red dot, and adjust the brightness. It can be adjusted from "1" (dimmest) to "11" (brightest). You'll have to be looking straight down the scope to see the red dot, since it is only visible when you're aiming. If you turn on the scope to the brightest setting, and you look through like you are aiming, and the red dot is still not there (or very dim) then you probably need to replace the battery. It uses a 3 Volt coin-style lithium battery, type 2032. Unscrew the battery compartment on top of the rheostat and put the new battery "+" side up. Then replace the battery cover, and you should be good to go. Turn off the scope when you're done to save the batteries.
Since you bought the rifle with the scope already installed, it's probably already sighted in, or pretty close to being sighted in. Adjusting the windage and elevation on the red dot scope works just like other rifle scopes. The knob on top moves the point of impact up/down, and the knob on the side moves left/right. For this model, each click of adjustment moves the point fo impact by 1/2" at 100 yds, 1/4" at 50 yds, or 1/8" at 25 yds.
