SH4 100 yard zero

Took my new SH4 6x24x50 to the range yesterday to get the gun zeroed in at 100 yards. Even with the scope adjusted all the way down, I am shooting about 6 inches high. There is no further adjustment, so I don't know what to try next. Scope is installed on a Sig Cross with Larue rings and was all installed by a gunsmith. Any ideas?

Thanks for the help.

You should still be able to get a good zero, even with the extra MOA. As dshuetz68 said, double check that your ZeroStop set screw isn't preventing it from going lower. You have a BUNCH of adjustment capabilities with any of the Arken Optics scopes.

Sig just got back to me. The Cross ships with a 20 moa rail installed so that's why I can't get it low enough. I'll zero at 200 or 300 now that I know what's going on.

I agree with dschuetz68, You should still have enough adjustment. I would suggest backing out the zero stop allen screw completely. I have a 20 MOA rail on my Ruger Precision Rifle and am zero'ed at 300 yards. I repositioned the zero stop plate ( not recommended because of the VERY SMALL set screws ) so that I could be zero at 300 and come down 7 MOA more .. though I only need to come down 4 MOA for 100 yards. Point being you should be able to zero at 100 even wth the 20 MOA rail.
