Description

Designed, tested and made in Queensland.

Six months of prototyping and range work went into the Shark platform, chasing a single result: the most consistent hop a gelball can be given. The Adjustable adds one thing to that — control. It’s printed in engineering resin: light, dimensionally stable, and strong where it needs to be.

Three custom elements, working together

The tongue. Length and surface texture engineered around a gel travelling at roughly 300 FPS — enough grip to spin the gel cleanly without deforming it.
The air porting. Excess compressed air is vented and dispersed before the gel is spun, so the hop is applied to a gel in clean air rather than one fighting its own pressure wave. The result is a flatter, straighter flight with far less vertical scatter.
The bottom lip. A custom profile that suppresses the side spin responsible for curving fliers — and side spin is what opens up a group more than anything else. This is where the tightest groups come from.

Dial it in

A grub screw sets tongue pressure, so you tune the hop to your gels, your spring and your barrel instead of hoping they all agree. Run unsorted gels, swap brands mid-season, change spring weight, move from a 7.5 mm barrel to a 7.3 mm — the Shark Adjustable comes with you.

Starting point: wind the adjuster in until it just contacts the tongue, then add hop a quarter turn at a time, checking groups at 10–15 m. When gels start climbing or tumbling at the end of their flight you’ve gone a touch too far — back off a quarter turn. Most setups land inside two full turns of the contact point.

Fitment

Inner barrel ID	7.5 mm optimal · 7.3 mm supported
Barrel OD	9.5 mm only
Exposed inner barrel required	12.8 mm
Mounting	Friction fit, grub-screw locked
Adjustment	Grub screw — in for more hop, out for less
Material	Engineering resin
Suits	Sorted or unsorted gels

Installation

Leave exactly 12.8 mm of inner barrel protruding. The Shark is a friction fit over that length — push it on square and fully home, then tighten the retaining grub screw. Set your hop last, once the unit is locked in position. Snug is enough on both screws; this is resin, not steel.

Before you order — check your barrel OD. The Shark mounts on the outside diameter of the inner barrel and fits 9.5 mm OD only. 7.3 mm and 7.5 mm IDs are both covered; OD is not negotiable.

Overall length 51.5mm, Overall width 18.5 mm
