The Leupold Mark 4 30mm medium aluminum scope rings (part no. 57398) secure a 30mm tube optic to Picatinny-style rails, engineered for consistent alignment and repeatable zero in precision and tactical shooting applications. Leupold machines the rings from aircraft-grade aluminum with a cross-slot design to maintain tight tolerances for reliable clamping, and included hardware — 6-48 and 8-40 shoulder screws plus half-inch keeper nuts — accommodates a range of recoil forces. The matte black finish reduces glare and helps maintain a low-visibility profile. Among tactical scope rings for 30mm optics, this Mark 4 medium configuration favors long-range and demanding field use.
