DuraSight Sighting Systems Cascade Long Action Picatinny Base — 1-Piece, 0 MOA, Black | DS616B | UPC: 043125516162
Mount your glass with confidence. The DuraSight Cascade Long Action 1-Piece Picatinny Base (DS616B) provides a rigid, optics-ready foundation for CVA Cascade Long Action rifles, delivering repeatable zero, broad ring compatibility, and worry-free durability in the field. With a true 0 MOA profile and full-length Picatinny slots, this base is ideal for hunters and precision shooters who want a clean, simple, and rock-solid interface for traditional scope rings, cantilever mounts, or red-dot/LPVO solutions.
Why Choose the DuraSight DS616B for Your Cascade?
Purpose-built fit: Designed specifically for Cascade Long Action receivers for proper screw alignment and footprint coverage.
True 0 MOA: Keep your scope’s internal elevation centered for maximum adjustment travel and a stress-free zero from typical hunting distances.
One-piece strength: A single rail ensures consistent ring spacing and improved rigidity compared to split bases—especially on magnum or heavy-recoiling setups.
Key Features & Advantages
0 MOA Picatinny Rail: Neutral cant for versatile zeroing from close woodland shots to longer cross-canyon opportunities.
Full-Length Slotting: Generous fore-aft ring placement for perfect eye relief with everything from compact 1-4x optics to long-tube 3-18x scopes.
Rigid One-Piece Construction: CNC-machined alloy with a protective black finish that resists corrosion, dust, and wet weather.
Wide Mount Compatibility: Works with most Picatinny-compatible rings and mounts (30mm, 34mm, 1" rings, and many QD bases).
Secure Hardware: Includes mounting screws matched to the receiver footprint (check package contents).
Low Profile: Keeps your optic closer to the bore for a more natural cheek weld and easier ballistic dope.
Note: Always verify receiver pattern (Cascade Long Action) before ordering. This base is not intended for Cascade Short Action or other rifle platforms.
Performance You Can Trust
Repeatable Zero: Tight tolerances and continuous rail geometry help maintain point of impact through travel, temperature swings, and recoil.
Flexible Setups: Run traditional scopes, LPVOs, red dots, or pair with a cantilever for night-vision clip-ons—your rail, your way.
Field-Ready Durability: The black protective coating shrugs off scuffs, rain, and cleaning solvents for season-after-season reliability.
Ideal Use Cases
Big-Game Hunting: A proven, no-drama mounting solution for whitetail, elk, mule deer, pronghorn, and more.
Backcountry / All-Weather: Lightweight, corrosion-resistant construction for storms, snow, and dust.
Range & Zero Day: Full-length slots make scope leveling and eye-box tuning simple on the bench.
Installation Tips
Verify Fit: Confirm CVA Cascade Long Action receiver.
Degrease: Clean receiver holes and screws; remove oils to ensure proper torque.
Thread Prep: Apply blue threadlocker (non-permanent) to mounting screws.
Torque: Tighten to manufacturer-recommended specs using an inch-pound torque wrench (commonly 15–25 in-lb; follow DuraSight/CVA guidance).
Level & Lap (Optional): Level the rail and use quality rings; lap if desired for maximum surface contact.
Re-Check: After the first range session or hike, verify torque.
