The only viable option for the franchi momentum - Burris XTR Signature 34mm Rifle Scope Rings

These rings made it possible to get some distance out of a Franchi Momentum 308 which does not accept anything other than two piece bases. As far as I know, they are the only rings that offer internal inserts that allow one to choose and implement MOA cant values form + 5 to +40. They are invaluable. Outstanding design, construction, and packaging make selecting these rings a no brainer! Mounted an Athlon Argos 6X24X50 using the 420221 one inch (Burris calls these medium) on a Leupold Mark Four 59230 two piece base kit, set the inserts at +5 and +20 for +25 MOA, and had ample clearance between the objective bell and the barrel.
