Looking at the epl4 6-24x50 in the Mil vpr. I have a savage arms mdx chassis 6.5 PRC, could I mix the moa ridgid mount to it, also would 0 moa be good or the minus 20 moa? The savage has a rail on it. Or would rings be better, this is my first fancy gun, I've only ever had just basic prior. Thank yo
