View Full Version : Use 0, 10 or 20 MOA scope mount?

With an AR 308 receiver that has 0 MOA, using a scope with say 80 MOA, zeroed at 100 yrds, if trying to pump it out up to 1000 yrds, would it better to use a scope mount with 0, 10 or 20 MOA?

Cant would be left or right tilt. A 20 moa base will usually do 100-1000 yards if your scope can get there.

Shouldn't need any more elevation (not cant) unless your 100yd zero is above "halfway" in elevation travel. You can get to 1K from a 100yd zero with much less than 40MOA.

20MOA. Better have it and not need it than need it and not have it.

20 MOA.

Just as a note usually only expensive scopes have that kind of adjustment.

20 MOA. 308 will need about 25-30 minutes of adjustment to get there. If you get a standard, all of that adjustment below your zero will be wasted.

Zero at 200 and use a 20MOA base.

Have a Leopold 3.5-10x Vari X III LR, has exactly 82.3 MOA.

Have a Larue 762 with 0 MOA receiver coming in about 4 months and picking up a Larue 556 with 20 MOA built-in in a few days, I'll get a 20 MOA scope mount for the 762 as suggested. For now, I'm just deciding if I should get a higher power scope for the 762 and maybe throw the 3.5-10 on the 556 or just keeping an Aimpoint micro on it instead and keeping it as light as possible.
