Scope mount recs for Nikon 5-20x44 on PTR91

[CFV]

PTR 91 A3R from Atlantic Firearms is in 10 day jail. Ordering a Nikon 5-20x44 and I don't know how I should mount this on the PTR. Not sure of the ergos of this rifle, should I get low, medium, or high rings. Was originally planning to use a Burris P.E.P.R mount. What do you guys recommend.

You'll need at least medium or high rings, a PEPR should just barely work. You'll have constraints on both the front and rear. For the back bell, the rear fixed sights will limit you to higher mountings, and even then you'll have to twist the sights to the 100m V notch for extra clearance. For the front , since your scope is 14" the front bell could interfere with the charging handle. The max practical scope length is around 12" long, any longer than that & you have compromises by having it too far back or too far forward.
