Weaver Mounts 48020 Top Mount Base 20A Black Gloss Mossberg 400/Remington 14/141

The Weaver Mounts 48020 is a single-piece Top Mount Base from the 20A series, machined from aluminum and finished in Black Gloss for a precise, custom fit on specific legacy rifle receivers.

Built around Weaver's iconic cross-lock design, this base attaches directly to the receiver in a top-mount configuration and is fully compatible with all Weaver top mount cross-lock rings (sold separately). The aluminum construction delivers maximum strength for rings to hold tight under recoil.

This 1-piece base fits the Mossberg 400 (rear) and Remington 14/141 (rear) rifles, and is also compatible with the Interarms Mark X (front). Each base is machined to tight tolerances for a custom fit, providing a secure and repeatable platform for mounting riflescopes and other optics.

Rings are not included. Made in the USA.
