Geissele Automatics Super Precision AR-15 Scope Mount 30mm Black - 05-404B - UPC 817953020166

Product Description

The Geissele Automatics Super Precision AR-15 Scope Mount is engineered for hard-use carbine platforms and precision marksman rifles requiring absolute zero retention under extreme conditions. Machined from a single solid billet of 7075-T6 aerospace-grade aluminum, this 30mm mount provides structural rigidity, shear strength, and thermal stability far exceeding standard two-piece ring designs. Finished in a durable Type III Hardcoat Anodizing, it resists abrasion, chemical exposure, and corrosion across all operational environments.

Utilizing Geissele's update on the classic nut-and-bolt rail clamping system, the mount interfaces with Picatinny rails using four surface-contact shear lugs and two high-strength steel clamping nuts. This clamping architecture generates up to 1,400 lbs of clamping force per nut, ensuring the mount remains immovably locked to your receiver rail despite heavy recoil, vehicle transport, or drop impacts. Each individual ring cap and base body are line-bored together during manufacturing to create near-perfect internal ring roundness, minimizing scope tube stress and eliminating the need for lap fitting prior to mounting optics.

Featuring a standard 1.54-inch optical height and a cantilever forward extension, the 05-404B delivers optimal eye relief and cheek weld alignment on flat-top AR-15 upper receivers. Whether hosting high-end LPVOs or precision intermediate scopes, this Super Precision mount provides an unyielding, match-grade optical interface engineered for military, law enforcement, and competitive shooting applications.

*Armorer Bench Notes & Real-World Staging Guidance:

Fitment Matrix: Fits 30mm maintube optics mounted on standard MIL-STD-1913 Picatinny receiver rails (AR-15 / M4 flat-top upper receivers). 1.54" height aligns centered with standard iron sight co-witness height.

1. Clean top upper receiver rail and scope tube surfaces with isopropyl alcohol to remove carbon, grease, and oil residues.
2. Place mount base onto the receiver rail, pushing forward toward the muzzle to seat the integrated shear lugs tightly against the Picatinny cross-slots. Tighten the base clamping nuts to 65 in-lbs using a torque wrench.
3. Install scope into bottom ring halves, apply cap screws with a light drop of Blue Loctite 242, and torque ring caps evenly in a cross-pattern to 15–18 in-lbs to prevent scope tube pinching or binding.
