Best scope in its price range. - Athlon Optics Helos BTR Gen II 2-12x42mm 30mm Tube Rifle Scope, First Focal Plane

If you're building an SPR, and this is your price range, this is the scope. Nothing beats it at this price. It has all the features youd want. Only thing I can ding it for, is it doesnt have as sharp of glass as a Viper PST or a Leupold... but those cost more, and those dont have all the featues that this does, like locking turrets and an actually GOOD reticle design. The 2-12 magnification range is perfect for a SPR out to distances that 5.56 is still terminally effective and also low enough magnification with a forgiving eyebox for closer range stuff. Serously. This is the scope you want if this is your price range.
