The one-piece Knight base for the Vision will work on the KRB7 as well. Just don't fully tighten any screws until you have them all started. Add a set of good QD rings and you would be in business. Medium height and maybe even some low rings would be fine using that base.

Look at the pic and you will see that base provides a lot of flexibility in positioning rings.

Thank you! The dealer I bought it from was NOT a Knight dealer.

Congrats on the new rifle.

Congrats! Let us know how it shoots.

Lets hear how she shoots. I'm curious as well, all my Knights shoot well with 250 gr shockwaves and 100 gr of pellets or loose power.
