Vector Optics 30mm 20MOA 1-Piece Extended Picatinny AR Mount (V-20 / XASR-3032) — Long-Range Ready, Rock-Solid Cantilever in Black Matte
The Vector Optics 30mm 20MOA 1-Piece Extended Picatinny AR Mount (V-20) is a precision, monoblock cantilever mount purpose-built for AR-pattern rifles that need correct eye relief and extra elevation for distance. With a built-in 20 MOA incline (≈ 5.8 mrad), it preserves more of your scope’s internal elevation so you can dial further, hold cleaner, and keep your reticle where it works best. A 38 mm (1.5″) optical center height gives a natural, heads-up posture on flat-top receivers, while the extended body pushes LPVOs and mid-power scopes forward to the right eye position. Full-CNC 6061-T6 aluminum, dual clamp nuts, and four screws per ring cap deliver a rigid, repeatable interface that holds zero through recoil and hard use.
Key Features & Advantages
- 20 MOA built-in cant: Conserves internal turret travel for reaching longer distances (typ. 400–800 m+ with suitable calibers and optics).
- Extended cantilever layout: Pushes the optic forward for ideal eye relief on AR-15/AR-10 platforms with LPVOs (1-6× / 1-8×) and mid-range scopes (2-10× / 3-15×).
- 30 mm monoblock rings: One-piece rigidity improves alignment and return-to-zero versus separate bases.
- AR-friendly height: 38 mm (1.5″) bottom-to-center height provides a comfortable cheek weld and clears common 24–50 mm objectives on flat-top rails.
- Dual clamp-nut interface: Steel cross-bolts bite into MIL-STD-1913 Picatinny rails for secure, repeatable clamping.
- Black matte anodized finish: Low-glare, corrosion-resistant surface ideal for duty, training, and competition.
- Even pressure on your scope: Four cap screws per ring distribute load across the tube to minimize marring and slippage.
Real-World Use Cases
Hunting & Practical Carbine
The cantilevered geometry lets you run the eyepiece where it’s fastest. The 20 MOA base keeps more “up” in your turret so you can confidently take longer shots across fields or clearings with .223 Wylde, .308 Win, or 6.5 Creedmoor gas-gun builds.
Precision & Steel
For gas-gun matches and steel practice, the added incline makes dialing simple and keeps your reticle’s usable holds near center. The one-piece body and cross-bolts resist shift from barricade pressure and positional recoil common in practical stages.
Training & Duty Carbines
Four-screw caps and dual clamp nuts offer “set-and-forget” reliability through high round counts, vehicle racks, and repeated zero checks. The included hex key allows quick field service when you need it.
Mechanical Strength & Environmental Protection
- Material: 6061-T6 aluminum, full-CNC machined for stiffness and ring concentricity.
- Finish: Black matte anodizing for durability and reduced signature.
- Rail interface: MIL-STD-1913 Picatinny with dual clamp nuts and steel cross-bolts.
- Torque guidance: Ring cap screws ≤ 18 in-lb. Clamp nuts typically 25 in-lb (acceptable up to 45 in-lb). Use a calibrated torque driver and tighten in an alternating pattern.
- Designed for hard use: Rigid monoblock construction maintains zero under recoil and rough handling.

Installation Notes (Best Practice)
- Seat the mount square on a clean, degreased Picatinny rail; snug the clamp nuts evenly before final torque.
- Level the rifle and scope; tighten ring caps in an alternating “X” pattern to the specified torque with even left/right gaps.
- If using thread treatment, apply a very small amount and follow “dry” vs “wet” torque guidance from your tool and hardware manufacturer.
- Add paint-pen witness marks to screws for quick visual checks during training or field use.
Summary
