These Badger Ordnance 30mm Max-50 ultra high scope rings are machined from steel barstock as serialized match pairs to ensure the rings are truly identical unlike mass produced rings. Designed to fit picatinny rails, these rings are finished with military specification black oxide. Max-50 rings have 60% more holding power, are 1" wide, and built to subdue the recoil of the .50 BMG.
