Geissele Super Precision 34mm Desert Dirt Extended Scope Mount 05-405S

Geissele Super Precision 34mm Desert Dirt Extended Scope Mount 05-405S, pushes the optic 1.16" forward of standard mounting position - built for shooters running an LPVO or magnified optic that needs its eye box moved off the receiver rather than crowded up against the charging handle.

The mounting surface spans 7 picatinny sections and carries recoil load through 4 shear lugs, machined into a single piece of 7075-T6 billet aluminum. That single-piece construction is what lets Geissele add strengthening ribs and pockets throughout the body without adding unnecessary weight, and it keeps cap locations consistent enough to accommodate a wide range of 34mm scope tubes without custom fitting.

Clamping runs through Geissele's nut-and-bolt system rather than a lever or cam — each combination pulls 1,400 pounds of force, considerably more than any lever-style mount generates, and it's the shear lugs doing the actual work of resisting recoil rather than the bolts alone. This is a Geissele Super Precision Scope Mount built for 34mm tubes specifically, and the extended geometry sits it at 1.54" of centerline height, enough to clear most rail-mounted accessories without shimming.

Geissele DDC finish keeps the mount in step with a desert-color build without breaking uniformity against a tan rifle.
