Nightforce all the way! EVERY rifle deserves a nightforce! Buy once, cry once and all that...
But seriously, the SWFA fixed power scopes are an excellent value. If you have a lower budget in mind here is one I would suggest:
BSA Tactical Mil-Dot Rifle Scope 30mm Tube 6-24x 44mm Side Focus Glass
I have one on a 22-250 and I really like it. Most folks will scoff at a BSA. Then again, most folks will scoff at a Mosin, so I would consider it a perfect match. The BSA is nowhere near as rugged as the SWFA's are. But, it is still a decent scope for the money.
On a side note, I continue to be amazed at the creativity being shown with the custom work people are doing to these rifles. There are some pretty neat conversions being done these days.
