The Durasight 0 MOA Picatinny Rail For CVA Cascade Long Action (DS616B) is a one-piece scope mounting base engineered specifically for CVA Cascade long-action bolt-action rifles. Constructed from high-strength aluminum alloy (Z2 alloy) with a glare-reducing matte black finish, this base provides a rigid MIL-STD-1913 Picatinny mounting rail across the rifle receiver. Designed to withstand heavy recoil from long-action calibres such as .30-06 Springfield, .300 Win Mag, and 7mm Rem Mag, it accepts both standard Weaver and 1913 Picatinny-style optic rings to establish a repeatable zero for hunting and range applications.

Key Features

• Dedicated Receiver Compatibility: Engineered specifically to match the screw-hole spacing and ejection port contours of the CVA Cascade Long Action receiver.
• Flat 0 MOA Elevation Profile: Maintains a neutral, parallel optic line relative to the barrel bore, making it suitable for zeroing optics at traditional hunting distances.
• Continuous Picatinny Cross-Slots: Provides flexible ring spacing for mounting standard riflescopes using either Weaver-style or MIL-STD-1913 Picatinny rings.
• Recoil-Resistant Alloy Construction: Built from durable aluminum alloy to handle the recoil impulses of magnum and standard long-action hunting cartridges without shifting zero.
• Included Hardware: Comes supplied with receiver-specific mounting screws (#6-48 pattern) for direct installation.

Who is the Durasight 0 MOA Picatinny Rail for CVA Cascade Long Action for?

• Big-Game Hunters — requires a neutral 0 MOA elevation incline on a CVA Cascade Picatinny scope base for shooting big game at typical field distances between 400 and 600 metres without requiring offset internal elevation adjustment.
• Target Shooters — needs a rigid 0 MOA Picatinny rail to mount standard optic rings directly to a CVA Cascade Long Action receiver chambered in calibres like .30-06 Springfield or .300 Win Mag without adding built-in downward barrel cant.

Less suitable for: Long-range shooters engaging targets beyond 600–1,000+ metres who will exceed their optic's internal dial travel and require an inclined 20 MOA scope base, as well as owners of short-action Cascade rifles or non-Cascade CVA platforms requiring a different receiver screw pattern.
