I have a Leupold Vari X III 4-12x and was wondering if it were possible to put tactical knobs on it. I wanna be able to use my 7mm mag Browning A-Bolt for tactical shooting and figured that putting tactical knobs on the scope (if I am able to, if I can't I'll go drink natty light and smoke two packs of cigs) would be the first place to start. I would also be interested in using it to shoot big game animals as well as squirrels. Thank you and I appreciate your input.
