Geissele Automatics Super Precision® Extended Scope Mount — 34mm, DDC (Desert Dirt Color), Hard-Anodized (05-405S / 05405S | UPC 817953020302)
When elite glass meets real-world conditions, you need a mount that won’t give an inch. The Geissele Automatics Super Precision® Extended 34mm Scope Mount in DDC (Desert Dirt Color) is engineered for shooters who demand uncompromising rigidity, perfect optical alignment, and confidence-inspiring return-to-zero. The extended cantilever geometry pushes your optic forward for ideal eye relief on AR-15/AR-10 platforms—perfect for LPVOs and mid/high-magnification 34mm scopes with larger ocular housings.
Finish Note: Geissele’s DDC anodize is unique. Product finishes, shade variations, and minor surface differences are normal due to the hard-anodizing process and the brand’s distinctive color recipe. Each mount’s tone may vary slightly—this is expected, not a defect.
Why Choose the Super Precision® Extended 34mm (DDC)
Monolithic, Single-Billet Construction: Machined from a single block of high-strength aluminum for exceptional torsional rigidity and precise ring concentricity—critical for tracking, dialing, and turret repeatability.
Extended Cantilever Design: Moves the scope forward on MIL-STD-1913 Picatinny rails, solving eye-relief challenges common to AR-pattern rifles, night-vision bridges, and heads-up shooting postures.
Geissele Shear-Lok™ Cross-Bolts: Oversized, precision-ground rail interface bites hard to resist fore/aft shift from recoil or barricade pressure, protecting your zero through rough seasons and travel.
True 34mm Rings w/ Optimized Clamping: Broad surface area distributes clamping force evenly to protect your scope tube, maintain optical alignment, and support repeatable accuracy.
Return-to-Zero Confidence: Remove and reinstall in the same rail slot with proper torque and expect POI to come back reliably—no re-zero headaches.
DDC Type III Hardcoat Anodize: Durable, low-glare finish that blends into sunbaked ranges and desert palettes while shrugging off abrasion and weather.
Built for Modern Optics & Real Conditions
Today’s LPVOs and precision scopes have larger ocular housings, throw levers, and tall turrets. The Super Precision Extended mount gives them room while keeping the scope exactly where your eye wants it—whether you run nose-to-charging handle or a more upright, heads-up stance. From recce and DMR builds to gas-gun PRS rigs, the mount holds alignment under prone recoil, tripod tension, and barricade pressure.
Ideal Applications
LPVOs (1–8x / 1–10x) with 34mm tubes that need forward placement
Mid/High-Mag Optics (3–18x, 4–16x, 5–25x) on AR-10/AR-15 or chassis rifles with Pic rails
Duty / Competition / Training where return-to-zero, rigidity, and durability are non-negotiable

Installation & Setup Tips
Prep & Degrease: Clean the receiver rail and mount interfaces; keep ring interiors oil-free.
Seat & Align: Place the mount fully into a consistent rail slot on the upper receiver (avoid bridging to a separate handguard unless monolithic).
Torque the Base: Tighten cross-bolts to Geissele’s specified torque with a calibrated driver.
Set Eye Relief: At max magnification, shoulder the rifle naturally and slide the scope until the eye box is perfect.
Level & Cap: Level the reticle to the bore; torque ring caps in an alternating “X” pattern, confirming even gaps.
Witness Mark: Add small marks on screws to monitor movement over time.
Confirm Zero & Tracking: Zero, then run a box/tall-target test to validate tracking and return-to-zero.
Real-World Advantages You’ll Notice
No Mystery Drift: Rigid, aligned mounting means your ballistic data stays trustworthy across temps and trips.
Cleaner Dial Data: Proper ring geometry reduces tube stress, helping maintain linear tracking.
Forward Relief Without Compromise: Extended cantilever achieves eye relief while preserving ring engagement and rail bite.
Pro-Grade Finish: DDC anodize is both tough and field-friendly, with unique tone variations that make each mount its own.
Pairing Suggestions
Optics: 34mm LPVOs (1–8x, 1–10x) and mid/high magnification scopes (3–18x, 4–16x, 5–25x).
Tools: Quality torque kit (Fix It Sticks / Wheeler) and a bubble/digital level set.
Accessories: Offset red-dot on the handguard if desired, plus a stable bipod or tripod for precise zero checks.
FAQs
Q: Will it fit any Picatinny rail?
A: Yes. It’s engineered for MIL-STD-1913 Picatinny rails found on AR receivers and many precision chassis.
Q: Do I need to lap the rings?
A: No. Geissele’s machining tolerances and ring geometry eliminate the need for lapping when installed correctly.
Q: Can I remove the mount and keep zero?
A: When reinstalled in the same rail slot and torqued properly, Super Precision mounts offer excellent return-to-zero.
Q: Why does the DDC color vary?
A: DDC is a hard-anodized finish with natural color variance. Shade differences and minor blemishes are normal and not defects.
