The Ruger receiver mounts are proprietary. And your rifle should come with 1" rings that fit them.
I'm not sure if the Matchdot has a 1" tube (25mm) or a 30mm tube. If it is a 1" tube, then yes, it will fit. That is exactly how I had one of mine set-up in the past. 30mm Ruger rings are also available.
Mounting the rail is easy. No gunsmithing. You remove the rifle from the stock, remove the handguard and remove the top half of the gas block. The gas block screws can be a bear to remove. They are staked in place once Ruger mounts the gas block. But they do come out with some patience and a quality allen wrench.
Then you bolt the mount to the gas block (replacing the upper gas block with the mount) and attach a band that wraps around the barrel about half way back.
The Amega Ranges
mount does add some weight to the rifle.
