I use the Tikka high rings on my T3 Lite in 22-250 for a 50mm 3X9 Conquest its a tack driver. Standard weaver type rings do not fit the Tikka groove imo.
Thanks for the feedback. It looks like extra high will be ordered just to be on the safe side. That's the problem with having no retailer nearby and buying sight-unseen...may have to pay a little extra in postage to get it right.
