I have a question about a scope rail combo.

Today i have a mrad razor hd2 on a 300 prc rifle.  it has a 20 MOA rail and the mount is 0 MOA that is 1.285 above the rail and zeroed at 200 yrd with no issue.  100 yrds also zeroed.

I am looking to swap that optic to a different rifle and get a new mrad razor HD3 optic for this rifle.  Looking at mounts, i found 2 that i would like to use:
-a 20 MOA mount (for a total of 40 MOA or about 12 mrad including the rail) that has a centerline of 1.5
-a 10 MOA mount (for a total of 30 MOA or about 9 mrad including the rail) that has a centerline of 1.4

I would like to get a 20 MOA mount (for a total of 40 MOA or about 12 mrad).  do you think i would be able to zero the rifle at 200 still with the extra 20 MOA?

This setup should work being able to zero at 200 yards (Possibly even 100 yards) as the Razor Gen III 6-36x has 36.1 MRAD of total elevation travel. As a general rule of thumb, it is best not to exceed more than half of the elevation travel with canted bases/mount. However, this is not a perfect equation as it will depend on the unique alignment of the firearm. Feel free to let us know if you have any other questions or give us a shout at 1-800-4VORTEX ext 5. Happy to help.

Thanks for that answer

You bet!
