I have a similar setup and went with the Talley steel bases and fixed rings. High quality for sure. The scope has 100 MOA of adjustment so I didn't think I'd need a canted rail to shoot at longer ranges. I think for rings and bases it was around $120 or so. I probably wouldn't get a picatinny rail mount for short range, but if you ever want to shoot past 1000 a 20 MOA rail would come in handy. The drawback is that it makes it harder to reach into the action. If you want a rail the Talleys are nice. EGW are cheaper and still decent quality but I prefer the Talleys for the nicely rounded corners. Going up in cost you can get a rail from Nightforce, Badger, Seekins or Near. For a rail or 2 piece weaver mount there are a few good rings available: Burris Tactical, TPS TSR, Vortex, Leupold Mark 4, Nightforce. I recently put some TPS super low 30mm rings on a Remington rifle with a Talley 20 MOA rail and it fits nicely with a 50mm objective. That setup was also around $120.
