Vector Optics 30mm 20MOA 1-Piece Extended Picatinny AR Mount, Coyote FDE (XASR-3036 / V-21) — Fast, Solid, and Built for Long-Range Holds
The Vector Optics 30mm 20MOA 1-Piece Extended Picatinny AR Mount is a rugged cantilever monoblock designed for modern AR-pattern rifles that need dependable eye-relief, rock-solid zero retention, and extra elevation for distance. With a built-in 20 MOA incline (≈5.8 mrad), this mount preserves more of your scope’s internal elevation so you can dial further or hold cleaner at longer ranges. A 38 mm (1.5") optical centerline delivers a natural heads-up shooting position on flat-top receivers, while the extended one-piece body pushes your optic forward for ideal LPVO and mid-power scope placement. Full-CNC 6061-T6 construction, two cross-bolts, and four cap screws per ring keep everything locked down under recoil—day after day.
Key Features & Advantages
- 20 MOA built-in elevation: Conserves internal turret travel for 400–800 m+ applications, making dope and dialing simpler at distance.
- Extended cantilever layout: Moves the scope forward for correct eye relief on AR-15/AR-10 setups with LPVOs (1-6x/1-8x) and mid-range optics (2-10x/3-15x).
- 30 mm rings (monoblock): One-piece rigidity improves return-to-zero and alignment versus two-ring bases.
- AR-friendly height: 38 mm bottom-to-center (≈1.5") provides a comfortable cheek weld and clears common 24–50 mm objectives on flat-top rails.
- Dual cross-bolt clamp: Two steel cross-bolts bite into MIL-STD-1913 Picatinny rails for secure, repeatable mounting.
- FDE hard finish: Coyote FDE matte anodizing reduces glare and blends with modern FDE builds.
- Field-ready details: Four screws per ring cap distribute pressure evenly over the scope tube; full-CNC machining ensures precise fit and alignment.
Real-World Use Cases
Hunting & Practical Carbine
- LPVO builds (1-6x / 1-8x): The cantilever offset lets you run the eyepiece where you need it for fast target transitions and both-eyes-open shooting.
- Early/late light: Stable geometry helps you keep the reticle steady on small vital zones when light and heart rate are working against you.
Precision & Steel
- Long-range holds: The 20 MOA incline (≈5.8 mrad) preserves elevation travel for dialing 500–800 m+ on .223 Wylde, .308 Win, or 6.5 CM ARs.
- Repeatability: One-piece body and cross-bolt clamp resist shift from positional recoil and barricade pressure common in PRS-style gas-gun stages.
Duty/Training Carbines
- Set-and-forget zero: Four-screw caps and dual cross-bolts resist loosening through classes, patrol use, or high-round-count practice.
- Glove-friendly serviceability: Included T15 driver and accessible hardware simplify maintenance and confirmation checks.
Mechanical Strength & Environmental Protection
- Material: 6061-T6 aluminum alloy, full-CNC machined for rigidity and consistent ring concentricity.
- Finish: Coyote FDE matte anodizing for corrosion resistance and reduced signature.
- Rail interface: 1913 Picatinny with dual cross-bolts for high clamp force and anti-shift under recoil.
- Torque guidance: Ring cap screws max 18 in-lb; base cross-bolts typically 25 in-lb (acceptable up to 45 in-lb). Always use a calibrated torque driver and tighten in an even, alternating pattern.

Installation Notes (Best Practice)
- Set the mount square on a clean, degreased Picatinny rail and snug the cross-bolts evenly before final torquing.
- Level the scope, then tighten cap screws in an alternating “X” pattern to the recommended torque, ensuring even gap left/right.
- Avoid excessive thread compounds; if used, follow “dry” vs “wet” torque guidance from your tool and hardware manufacturer.
Summary
