The Primary Arms PLx 30mm Cantilever Scope Mount is a premium one-piece mount for 30mm scopes on Picatinny rails. This 1.5in height gives a standard optical centreline that suits most LPVO and rifle-scope builds where a lower, conventional sight line is preferred.
Built from 7075 aluminium with grade 12.9 steel hardware, a three-bolt design, dual recoil lugs and three cross-bolt lugs, it delivers over 6,500 lbs of clamping force for rock-solid, repeatable mounting.
