I am in the process of having a USMC spec M40A3 built. I plan on using the S&B 3-12X50 PM II Military scope with it. If I use the 30 MOA optical platform will I still be able to use this rifle scope combination for closer distances such as 100 yards? Or should I use a 20 MOA for occasional 100 yard use?
Rifle Scopes 20 or 30 MOA?

Re: 20 or 30 MOA?
I'm not 100% familiar with the 3-12, but I would be VERY surprised if you couldn't get a 100 yard zero with a 30moa base.
I have a 40moa base on my Hensoldt 4-16 and get a 100 zero.

Re: 20 or 30 MOA?
I would stay at 20MOA... That will keep you good at 100 and still take you to 1000 yards.
The 30 MOA COULD have issues at being zeroed at 100 yards.

Re: 20 or 30 MOA?
If the scope is in mils, then you have 220 cm of elevation per the S&B specs. This is about ~85 MOA of adjustment. With a 30 MOA rail, you should have about ~12.5 MOA remaining down travel in the scope with a 100 yard zero. With a 20 MOA base, you will have more down travel (~22.5 MOA).
If it's an MOA turret scope, the S&B specs show only 56 MOA of travel. With a 30 MOA base, it puts you about 2 MOA short of a 100 yard zero. So, if it's an MOA turret scope, go the 20 MOA base. If it's a mil turret scope (which it sounds like it is), then either base will work.

Re: 20 or 30 MOA?
I run pretty all 30MOA bases across the board with my S&B scopes... never once was a 100 yard zero an issue.
They work best with 28MOA so a 30 is a fine compromise.

Re: 20 or 30 MOA?
It all depends on what distance you will be doing most of your shooting. I run all mine at 20 MOA and have shot at 1200 yards in matches without any issues.
Looks like the S & B scopes have a really good elevation spread that will get you down to 100 with either rail. If you are custom building, you could spec a 25 MOA rail and get the best of both worlds.
