Geissele Super Precision 30mm Hyper Extended Scope Mount 05-374S

The Geissele Super Precision 30mm Hyper Extended Scope Mount 05-374S was designed for AR-type uppers where a longer reach and an ultra-secure hold both matter. It's built around the same clamping philosophy that runs through the whole Super Precision line: the mounting surface spans seven picatinny sections and locks down with four shear lugs and two separate nut and bolt combinations, each delivering 1,400 pounds of clamping force. That's a steadfast hold that doesn't budge, even under heavy recoil.

This Geissele Super Precision 30mm mount starts as a single piece of high-strength 7075-T6 aluminum, milled rather than assembled, which is what makes its return to zero so consistent. Machining from one billet lets Geissele add ribs and pockets through the body for extra rigidity without extra weight, and it allows the bore caps to be lined up to one another for a near-perfect fit. That precision fit means you can torque the caps down properly without any risk of crushing or marking the scope body underneath.

The extended footprint is what sets this Geissele 30mm scope mount apart from the standard Super Precision options, giving shooters more flexibility in scope placement without sacrificing any of the clamping strength or rigidity the line is known for. It's a mount built for setups that need that extra reach, without compromising on how securely the optic sits once it's torqued down.
