Geissele Automatics Super Precision® Extended Scope Mount — 34mm, Black, Hard-Anodized (05-405B / 05405B | UPC 817953020289)
When your glass is elite, your mount should be too. The Geissele Automatics Super Precision® Extended 34mm Scope Mount in black hard-anodized finish is engineered for shooters who demand uncompromising rigidity, perfect alignment, and repeatable return-to-zero on modern carbines and precision gas guns. The extended cantilever geometry pushes your optic forward to achieve proper eye relief with today’s larger ocular housings and forgiving eye boxes—ideal for LPVOs and mid/high-magnification 34mm scopes.
Why the Super Precision® Extended 34mm Is a Standout
Monolithic, Single-Billet Construction: Machined from a single block of aluminum for torsional rigidity and precise ring concentricity—critical for tracking and turret repeatability.
Extended Cantilever Geometry: Moves the optic forward on MIL-STD-1913 Picatinny rails to dial in eye relief on AR-15/AR-10 platforms, night-vision bridge setups, or heads-up shooting positions.
Geissele Shear-Lok™ Cross-Bolts: Oversized, precision-ground rail interface resists fore/aft shift from recoil, barricade pressure, and heavy use—protecting your zero through hard seasons.
True 34mm Rings with Optimized Surface Area: Even clamping force around your scope tube helps prevent marring, maintains optical alignment, and supports repeatable accuracy.
Return-to-Zero Confidence: Remove and reinstall in the same rail location with proper torque and get your POI back—no drama, no re-zero headache.
Black Type III Hardcoat Anodize: Low-glare, abrasion-resistant finish that stands up to range abuse, weather, and constant handling.
Purpose-Built Heights (Family): The Super Precision series offers height variants designed for LPVOs, 3–18x, 4–16x, 5–25x class optics; confirm the exact height spec that fits your cheek weld and backup-sight plan.
Built for Modern Optics & Real-World Use
Large ocular housings, throw levers, and dial-heavy turrets are standard now. The Super Precision Extended mount gives them room to breathe while keeping the scope exactly where your eye wants it—especially useful for shooters running nose-to-charging-handle or heads-up postures. From recce rifles and DMR builds to gas-gun PRS rigs, this mount keeps your glass locked down and aligned when you’re shooting prone, braced on a barricade, or hanging off a tripod.
Ideal Applications
LPVOs (1–8x / 1–10x) with 34mm Tubes needing forward placement on ARs
Mid/High-Mag Scopes (3–18x, 4–16x, 5–25x) on precision gas guns or lightweight bolt guns with Pic rails
Duty/Competition/Training where return-to-zero and resistance to shift are non-negotiable

Installation & Setup Tips
Degrease & Prep: Clean rail slots and mount interfaces; keep oil off ring interiors.
Place & Align: Set the mount on the receiver (avoid bridging to handguards unless monolithic). Seat fully into a consistent rail slot.
Torque Base: Tighten cross-bolts to Geissele’s specified torque with a calibrated driver.
Set Eye Relief: At max magnification, shoulder the rifle in your natural position, then slide the scope to find your perfect eye box.
Level & Cap: Level the reticle to the bore line, then torque ring caps in an alternating “X” pattern to the specified inch-pounds—verify even gaps front and rear.
Witness Mark: Add small paint marks to screws to monitor movement over time.
Confirm Zero & Tracking: Zero, then run a box test or tall-target test to confirm dial accuracy and return-to-zero.
Real-World Advantages You’ll Notice
No Mystery Drift: A rigid, aligned mount keeps your dope trustworthy between range days, temperatures, and trips.
Cleaner Turret Data: Proper alignment reduces scope stress, helping maintain linear tracking and precise returns.
Forward Relief Without Compromise: Extended cantilever achieves eye relief without sacrificing ring engagement or rail bite.
Pairing Suggestions
Scopes: Premium 34mm LPVOs (1–8x / 1–10x) and 34mm mid/high-magnification optics (3–18x, 4–16x, 5–25x).
Tools: Quality torque kit (e.g., Fix It Sticks/Wheeler) and a bubble or digital level system.
Accessories: Offset red-dot at the handguard or a top-mounted micro (if your discipline prefers), plus a sturdy bipod/tripod for zero checks.
Frequently Asked Questions
Q: Will it fit any Picatinny rail?
A: Yes—designed for MIL-STD-1913 Picatinny rails common on AR receivers and many chassis systems.
Q: Do I need to lap the rings?
A: No. Geissele’s machining and ring geometry are designed to eliminate lapping when installed correctly.
Q: Can I remove the mount and keep zero?
A: When reinstalled in the same rail slot and torqued to spec, Super Precision mounts deliver excellent return-to-zero.
Q: What height is the 05-405B / 05405B?
A: The “Extended” 34mm variant is offered in height options appropriate to LPVOs and precision scopes. Verify the exact height against your optic and cheek-weld requirements.
