Sun Optics 20 MOA Remington S/A Picatinny Style Tactical Base

The Sun Optics 20 MOA Picatinny Style Tactical Base is a precision-machined mounting rail designed for Remington Short Action (S/A) rifles. With a 20 MOA upward cant, this Picatinny rail helps shooters retain more elevation adjustment in modern optics — especially beneficial for long-range targets. Built from aircraft-grade aluminum and finished in matte black, it offers a stable, rugged foundation for scopes, red dots, and other accessories.

Key Features

Designed for Remington Short Action:
• Tailored to fit the receiver on Remington S/A rifles so the rail aligns correctly with the drilled and tapped mounting points.

20 MOA Built-In Cant:
• The rail’s 20 MOA slope gradually raises the rear of the optic relative to the front, allowing scopes to stay closer to center of their elevation travel when shooting at extended ranges.

MIL-STD-1913 / Picatinny Pattern:
• Standardized rail slots accept most Picatinny-style scope rings and mounts, giving you flexibility with optics and accessories.

Aircraft-Grade Aluminum:
• CNC-machined from high-quality aluminum, the base provides strength while keeping weight minimal.

Black Anodized Finish:
• Durable anodizing delivers corrosion resistance and a low-glare tactical look that complements a wide range of rifle finishes and optic setups.

One-Piece Construction:
• A single, seamless unit adds rigidity compared with multi-piece designs and helps maintain alignment under recoil.

Mounting Hardware Included:
• Screws and wrench are supplied for installation, making setup straightforward — just align and fasten to your rifle’s existing holes.

Technical Specifications

Scope rings and optics are not included.

Performance & Practical Use

Adding a 20 MOA cant-rail helps align your rifle for long-range shooting without forcing you to use the maximum internal elevation of your optic. This is especially useful when zeroing a scope for targets out past typical engagement distances — the built-in upward slope ensures you retain plenty of travel in the scope turrets for dialing in elevation.

Because it uses the standard Picatinny rail pattern, you can pair it with a wide array of scope rings, quick-detach mounts, and other accessories that conform to MIL-STD-1913. Machined from durable aluminum, it holds up well under repeated recoil and normal field use, making it a solid choice for hunters and tactical shooters alike.

Best Suited For

✔ Remington Short Action owners upgrading to a Picatinny rail with cant
✔ Shooters needing extra elevation adjustment for long-range optics
✔ Users mounting scopes, red dots, night vision, or other standard accessories
✔ Builds where a single, rigid base is preferred over two-piece designs

User Tips

Check Your Receiver Pattern:
Before installing, ensure your rifle has the drilled and tapped holes matching the Remington S/A standard — this base won’t fit mismatched patterns.

Torque Properly:
Use recommended torque specs when tightening screws to avoid straining receiver threads or the rail.

Choose Rings Wisely:
Pair with quality Picatinny rings suited to your scope’s tube size and desired eye relief — this maximizes performance and comfort.

Align Before Final Torque:
Install the rail loosely first, check alignment and level, then torque the screws to final specs to ensure the best optic alignment.
