I have 2 sets of Knight quick detachable scope rings that are stainless in color, and a 2 sets of Knight bases that say they fit a MK. The item number of the bases is 900760 and the item number of the rings is 900770. Both sets of rings are unopened, and one set of bases is sealed, and the other was opened by me to look at it, but it's never been mounted on anything, so it's all new, and all screws are included. I have no idea what these really sell for other than the price tag on them says $46.09 for the rings and $16.80 for the bases. A quick Google search showed the rings selling online for $30.
Get these and be prepared for the upcoming muzzle loader season.
I'd take $15 shipped for each set of bases and rings.
