The Burris Throw Lever provides a simple mechanical advantage for faster and easier changes in magnification on your variable riflescope. Allowing you to adjust the magnification of your scope to the ideal setting for your current engagement. Whether it’s cold and you’re wearing gloves, or it’s your first time at a match, and you’re palms are all sweaty because you are nervous and oops you just realized you accidentally wiped your dope off your armband (man, you really should have bought a Race Dial while you were ordering the throw lever).
