What ring height for 20 moa egw base/SIII 8-32x56

Hi fellas: I just purchased a new model 12 F class in 6.5x284 and have a EGW 20 moa base coming in the mail,i have a Sightron SIII 8-32x56 scope that i want to install with Burris sig. Z 30mm rings but not sure if mediums will work or do i need highs,i don't want to buy both and go through the return crap.Any help would be greatly appreciated!!!

Personally I would get the extreme rings but thats up to you.
The extreme rings are low 1/4", med 1/2", high 3/4", ex High 1"


The medium signature Z ring is probably too low
The heights are med .205, high .330, extra high .455

If you dont want to return, you probably should tape up some paint sticks or some other spacer
to the correct ht, put them on the rail and check the scope clearance.

Tammons: i have had burris extremes in the past and really liked them but next to impossible to get here in Canada,and i have had good luck with the sig.Z in the past.Good idea on the paint stick thing

I have a Savage F class in 6mmBR with the same scope. I have a Ken Farrel 0 MOA rail and used Burris Sig. Zee MEDIUM rings with +10 and -10 inserts installed and have about 1/8" clearance under the front of the scope.

Cover dog: i was wanting a 6br for 2 years and we still can't get any in Canada,so i decided on the 6.5x284.i know farrell bases are taller than most so i think high "Z" rings should be okay i hope !!

I have 30mm Signature Zee medium rings on a 20moa Weaver base. With -10/+10 inserts and a 50mm obj, I still have at least 1/8" clearance over my bull barrel.

Other than the caliber(I have the 308 F/TR) i have the same set up and agree with Tammons, use the extreme rings. I have EGW 20moa base with medium extreme rings and sightron Slll 8-32 scope on it. I put the Slll 10-50 on the new F/TR i just built and the mediums are just about .050 to low to allow the sightron lens cap to go on easily. I have to stretch it so it will fit and take it off for clearance when i shoot.
