I highly recommend a 20 MOA base because it will keep the optical elements closer to the center of the lens stack and light pathway when the erector moves the inner tube for elevation adjustment. 24” 6.5CM doesn’t normally have issues with bottoming out the erector, but it’s better to be closer to the optical true path.
Make sure the scope base and action are degreased completely before installing, and use at least Red Loc-tite 272 when attaching the scope base to the action. I personally form an “o”ring on the base with LT-272, after scuffing the surface up for better adhesion between the bottom of the base and the top of the action. You don’t ever want the base to come loose. I use acetone to degrease the base and action before securing the base. Make sure to get the fastener threaded channels cleaned out as well. They like to accumulate oil from the factory.
You can use EGW or NightForce 20 MOA bases. NF is aluminum. Make sure you have a torque wrench when torquing the fasteners down and know how to compensate for setting them in with Loc-Tite. I do bases with LT-272, and rings with Blue LT-242.
Depending on what direction you go, you can do both single piece or individual rings. Most do individual rings on bolt actions. A Spuhr mount will run you a lot more than most rings.
Seekins, NightForce, and Warne make quality rings. I would steer you to Seekins, then NF.
Most Pro PRS shooters use Spuhr or MPA single-piece mounts, but that’s at a top-tier National competitive level.
Be sure not to over-torque your ring fasteners. That’s where the torque wrench comes in.
I use the Wheeler FAT Wrench for all my inch-pound torque wrench needs.
I don’t trust most of the guys that LGSs call “gunsmiths” to get any of this right, because there are lot of people playing gunsmith that aren’t really well-trained or smart. When you do find a competent gunsmith, they are worth their weigh in gold. All of them will convince you they have the keys to success in an initial conversation. Once you see their work, then you’ll know what you’re actually dealing with if you know what to look for.
Best to learn how to do a basic rifle set-up yourself since it isn’t that difficult if you have the right tools and a brain.
