Product identity

The Hawke Sport Optics 22405 is a two-piece riser adapter base that converts a 3/8 inch dovetail rail on a rifle to a Weaver-style mounting platform. It is built for hunters and outdoor shooters who need to attach Weaver-compatible scopes or accessories to a traditional dovetail receiver.

Critical specification

The adapter accepts a 3/8 inch dovetail input and provides a Weaver-pattern output, so the single deciding factor is whether the host rifle uses that exact dovetail width. If the receiver uses a different dovetail size or an integral rail, this base will not fit.

Sustained use

Sturdy construction and high-quality materials maintain a secure lock-up under repeated recoil and field handling, preventing zero shift during extended shooting sessions. The two-piece design distributes clamping force evenly, preserving alignment through temperature changes and rough transport. Not suited for rifles with proprietary rail systems or dovetail widths other than 3/8 inch.

Questions about this item

What does the 3/8" dovetail-to-Weaver conversion mean once the adapter is on my rifle?

It lets you mount any Weaver-pattern scope ring or accessory onto a rifle that only has 3/8" dovetail slots.

Which mounting standard does the adapter output, and what does that limit?

The top surface follows the Weaver cross-slot pattern, so only Weaver-compatible rings or bases will clamp securely.

What does the two-piece riser design need to fit on the rifle?

Two separate 3/8" dovetail slots spaced to match the adapter bases; each piece clamps onto its own slot.
