Vortex Precision Matched Rings (part #PMR-30-87) are machined in the USA from 7075-T6 billet aluminum and kept together as a serialized pair through manufacturing. Held to a tolerance of 0.0005″, the two rings are concentric right out of the box, so they hold a 30mm scope without lapping. This set has a low 0.87″ center height and mounts to Picatinny rails.

FAQ
Will these fit my scope?
They fit scopes with a 30mm main tube. Check your scope’s tube size before ordering; 1″, 30mm and 34mm rings are not interchangeable.
How do I choose ring height?
Pick the lowest height that lets the scope’s objective bell and eyepiece clear the barrel, rail and bolt handle. A lower height usually gives a better cheek weld; larger objectives need taller rings.
