Talley MPR400 Picatinny Rail Mount for Beretta A400 Shotgun

The Talley MPR400 transforms your Beretta A400 into a precision optics platform with its machined aluminum Picatinny rail mount. This black anodized mount eliminates the guesswork of mounting micro red dots and other optics on your semi-automatic shotgun.

What Makes This Different

Unlike universal rail systems that require modification or compromise fit, the MPR400 is engineered specifically for the Beretta A400's receiver dimensions. The mount replaces the factory rear sight base with a full-length Picatinny rail that maintains the shotgun's original sight plane. This direct replacement design ensures consistent zero retention and eliminates the flex common in clamp-on rail systems.

Key Features

• Machined from 6061-T6 aluminum with Type III hard anodizing for corrosion resistance
• Direct replacement for factory rear sight base - no gunsmithing required
• Full MIL-STD-1913 Picatinny rail specification for universal optic compatibility
• Black anodized finish matches factory Beretta components
• Maintains original sight height for co-witness capability
• Compatible with micro red dots, holographic sights, and magnified optics
• Includes all necessary mounting hardware and installation instructions

Field testing demonstrates the MPR400's ability to maintain zero through thousands of rounds of heavy waterfowl loads and slug ammunition. The rigid aluminum construction absorbs recoil without shifting optic position, while the hard anodized surface resists scratches from blind walls and transport cases. Competition shooters report consistent point of impact with rapid target transitions, while hunters appreciate the low-profile design that won't snag on vegetation.
