With so much competition, finding cheap optics for your rifle isn’t too difficult a chore. For the inexperienced buyer, however, the specifications of these optics may be misleading. It’s also easy to get hoodwinked into buying a scope that looks good on paper but lags behind others on the shooting range.

We will assess several variables such as magnification, stability, reticle, and focal plane to determine the best scope for AR 15 under $100.
