The EGW Mossberg Patriot Long Action 0 MOA Picatinny Scope Base (brand part no. 45800) is machined by Evolution Gun Works specifically for the Mossberg Patriot’s long-action receiver, giving shooters a one-piece Picatinny rail that bolts on with factory screw spacing. The flat 0 MOA design suits typical hunting and range distances where extra elevation reserve isn’t needed, and the billet construction holds zero reliably through repeated recoil compared to lighter stamped bases. It’s a straightforward upgrade for Patriot owners replacing factory bases or moving to a wider selection of Picatinny-compatible rings and mounts.

Key Specifications

• Manufactured in the USA from billet material for a precise, repeatable mount.
• Sold as a single-piece base rather than a two-piece rail system.
• Uses the factory screw pattern for a bolt-on installation.

Frequently Asked Questions

Will this fit the Mossberg Patriot short action? No, this base is sized specifically for the Patriot’s long-action receiver.

Why choose 0 MOA instead of an elevated base? 0 MOA keeps the scope’s usable elevation adjustment centered, which suits typical hunting and range distances rather than extreme long-range shooting.
