I am looking for optic and mount advice for the Scar 20 I have just purchased. This rifle wil be used for shooting precision rifle matches. The optic I have in mind is a Vortex Razor HD 4.5-27 X 56. I am looking at mounts and really don't feel I need a QD mount for this rifle. Not against a QD mount just dont feel it is real needed if I can save a little coin on a quality non-QD mount. I am also interested in a mount that has a built in bubble level. Anyone have any input? Advice is welcome! Thanks!
