Only because you're on a budget.


Otherwise (worth it);

50 MM or bigger objectives are going to require high(er) rings.

You want the lowest mount possible, so that your check can "weld" to the shock as you look through the scope.

BDC reticles are for long range shooting - all of which takes a lot of practice to become familar with !
