LWI Shark Hop-Up — Fixed

$40.00

Precision gelball hop-up, designed and made in Queensland. Six months of development in one part: an engineered tongue profile, vented air porting and an anti-spin bottom lip. Factory-tuned for sorted gels on a 7.5 mm ID / 9.5 mm OD barrel — set, locked, no guesswork.

Description

Designed, tested and made in Queensland.

Six months of prototyping and range work went into this unit, chasing a single result: the most consistent hop a gelball can be given. 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.

Factory-tuned, not adjustable

This variant is finely tuned around sorted gels at approximately 7.35 mm. There’s nothing to dial in and nothing to drift: fit it, lock it, shoot it. On graded gels it is the most consistent setup we build.

Fitment

Inner barrel ID 7.5 mm
Barrel OD 9.5 mm only
Exposed inner barrel required 12.8 mm
Mounting Friction fit, grub-screw locked
Material Engineering resin
Tuned for Sorted gels, approx. 7.35 mm

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 grub screw to stop it shifting under recoil. Snug is enough; 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. ID tolerance we can work with; OD we can’t.

Sort your gels. Without graded gels, diameter variation will show up as inconsistent hop and you won’t see what this unit can do. If you don’t sort, buy the adjustable Shark instead — it’s built for exactly that.

Overall length 51.5mm, Overall width 18.5 mm
