Geissele Super Precision 34mm Extended Blk

Geissele Super Precision 34mm Black Extended Scope Mount 05-405B, pushes the optic 1.16" further forward than the standard-length version - built for shooters running an LPVO that needs its eye box moved off the receiver rather than sitting close to the charging handle.

Body and rings are cut from a single piece of 7075-T6 billet aluminum, caps included, then line-bored and serialized to that specific body. That's not a cosmetic step - it's what lets you torque the caps down to spec (72 in-lbs, no more) without the ring geometry crushing the scope tube or leaving a high spot that shows up as stress on the glass. The mounting surface spans 7 picatinny sections and carries the load through 4 shear lugs, so recoil transfers into the mount body rather than the clamp hardware.

Clamping itself runs through Geissele's nut-and-bolt system rather than a lever or cam - each pair pulls 1,400 pounds of force, considerably more than a lever-style mount can generate, which is the mechanical reason this thing doesn't creep under sustained recoil. At 7.2 oz it's not the lightest 34mm scope mount on a rail, but weight wasn't the design target here - return to zero after repeated mounting and dismounting was.

For a Geissele 34mm mount built to push eye relief forward, 05-405B is the extended option in the Super Precision line - the standard-length 05-417B covers the same tube size without the added reach.
