I know I've had the no drill mount for over a year now however a slew of unpleasant medical issues has kept me from installing it until this weekend. I have to say I'm very happy with the quality and functionality and look forward to sighting it in and having my 99 ready for this year's hunting season. Hopefully I can have a range report to post within the next few weeks. I have it set up with my Weaver K4 60B mounted and ready to go. Thanks again and sorry to have been one of "those guys" that take forever to respond.
