15 or 20 MOA Rail

(1/2) > >>

Dwayne Cyr:
On short range bench rest actions with 3/8" Davidson style rail, how do you add 15 or 20 MOA to shoot 600 yards?

Are there rings that do this?

Thanks

Dwayne

On my Bat Model B in 6 BR , i have the BAT rings all one piece 20 moa . Bat  makes a 3/8 dove tail base one piece in 20 moa as well . from what i have seen, its normally in the base that you can choose your moa  ie - 10, 20 ,30  . hope this helps . Steve

Dwayne Cyr:
Found 2 solutions:

Kelbly's make a set of 30 mm rings with 25 MOA of elevation built in.

Stiller used to make a set of 1 inch rings with 20 MOA that need 4.5" of spacing.

The 30mm scope that's on the gun has 50 MOA of elevation travel so I'm going to try dialing in elevation to get zeroed at 500 meters.

The load needs 11" of elevation at 100 for a 500 meter zero. If the scope runs out of elevation, I'll get the rings.

Yes, the direct ring mount is nice , with the moa built in . i have used 3 different scopes over the years with my Bat direct ring mount 20 moa , i shot 600 yard with all of them , never had a problem with running out of elevation .  i see harrells makes a moa one piece base too.   interesting too see if you run out of elevation with your scope , with no moa base , let us know . steve   

Dwayne Cyr:
You do understand the rail is machined into the top of the receiver?

Replacing it with a 20 moa rail is not an option.
