Re: IOR 3-18x42 Tactical

I use IOR scopes, their rings will fit a standard Picatinny spec base, not weaver bases as they are different. Weaver bases use a smaller cross notch than a Picatinny rail base.

Yes be very carful on the rings with IOR scopes, i had problems with my 6x24 scope. The front ring was just a bit too tight and the side focus got snug.

I am concerned about the way you shimmed the base on the rifle, If you check the rings are prolly out of alinement now. You should look into a milled rail, that way the rings will be in line with each other. If the rings are not perfect the scope will be binded or pinched. You can check this with a straight edge laying it accross the inside of the rings.

Re: IOR 3-18x42 Tactical

when I mounted the USS 4x16 on my 7mm AM with farrel 2 pc 20 MOA bases, I couldn't go down enough to make zero, so I replace the farrel's with a set of weaver GS bases, the IOR rings fit them just fine.

Still liking the scope Vic?

I figured I'd let people know, if you're interested in the FFP/New Knob/Non-illuminated version of the 3-18, now is the time:;f=19;t=006248
