This is not for a bolt action rifle, it is for my lever action rifles that use straight tube scopes. The rifle is a Savage 99 lever action rifle re-barreled in 450 Bushmaster with a Swaro 1x6 EER scope. With the stock design, I need the scope as low as possible. If these work on the 450, I am buying another set for the .308 Savage 99 I have in a similar setup. The pic of the rifle below is low rings from another manufacturer, not the Hennebergers.
I am going to be doing a lightweight mountain rifle later this year and it will probably get these rings also but maybe not 3.5mm low as there may be clearance issues.
