What it is

The Hawke 1 Piece Adapter Picatinny (Extended), model 22402, is a single-piece aluminium base that converts a 9-11mm airgun dovetail or a 3/8in rifle dovetail into a full Weaver/Picatinny rail. That opens your rifle or air rifle up to the huge range of modern rings, optics and accessories built for Weaver/Picatinny fitment.

Adjustable elevation

A rear set screw lets you gradually tilt the rail top downwards towards the trajectory of your pellet or round. This is ideal for overcoming barrel droop or compensating for heavy drop at longer ranges, so you keep more usable adjustment inside your scope turrets.

Built to hold zero

A forward position stop prevents the base creeping down the dovetail under recoil, while quad hex (3mm) fixings on an 8-32 thread clamp it down firmly. At roughly 96g it adds minimal weight.

Getting set up

Pair it with matching rings and an optic from our outdoor shooting range, or browse related airsoft accessories for mounting hardware.

Frequently asked questions

What rails does this adapter fit?

It clamps onto a 9-11mm airgun dovetail or a 3/8in (9.5mm) rifle dovetail rail and gives you a Weaver/Picatinny top surface for modern mounts and optics.

Does it add elevation for longer ranges?

Yes. A rear set screw lets you gradually tilt the Weaver top downwards towards the trajectory, which helps overcome barrel droop or heavy bullet drop at distance.

Will it move under recoil?

A forward position stop holds the base in place so it does not creep down the rail during recoil, keeping your zero stable.

What tools do I need to fit it?

The rail fixings use quad hex (3mm) screws on an 8-32 thread, so a standard 3mm hex/Allen key is all that is needed to mount and adjust it.

Is this the extended version?

Yes, this is the extended Hawke 22402 base with a longer rail than the standard 22401, giving more room to position rings or accessories.
