The specs for this scope show it has 50 moa total adjustments. I just puchased a DPMS LR308(.310 high rise rail) now if I add a 15 or 20 moa base and IOR high height rings (.75") do any of you foresee a problem making a 100 yd zero. This is my first semi for long range and probably the most limited scope in terms of elevation ( If I buy it)
