Replacement AUG hop-up unit

This hop-up unit is a replacement for Steyr AUG series airsoft AEGs. The hop chamber applies backspin to the BB as it leaves the barrel, and a worn or cracked chamber is one of the most common causes of dropped range, inconsistent grouping and poor feeding.

Wide compatibility

It is built to Tokyo Marui AUG dimensions, so it fits the common AUG replicas and clones from brands such as JG, ASG and CYMA that share the Marui pattern. It works with standard AEG-style inner barrels, so you can reuse your existing barrel and hop rubber.

Simple hop adjustment

A rotary hop adjuster lets you dial the backspin up or down to suit your BB weight and get a flat, level flight to maximum range. Once set, it holds position through normal skirmish use.

Fitting and support

Fitting an AUG hop unit means opening the gun, so if you are not confident stripping the receiver our technicians can do it for you through our airsoft gun repair service in Kent. Find matching parts in our airsoft accessories range.

Product information reviewed by James Smith. Every gun is checked & serviced by our Rochester workshop before dispatch.

Frequently asked questions

Which guns does this AUG hop-up unit fit?

It is built to Tokyo Marui AUG dimensions, so it fits the common AUG replicas and clones that share the Marui pattern, including many JG, ASG and CYMA models.

Does it work with my existing inner barrel?

Yes. It accepts standard AEG-style inner barrels, so you can reuse your current barrel and hop rubber if they are in good condition.

Why would I need to replace the hop-up unit?

A cracked or worn chamber is a common cause of dropped range, inconsistent grouping and poor feeding. A fresh unit restores a proper air seal and hop.

How do I adjust the hop?

The rotary adjuster lets you dial the backspin up or down to suit your BB weight for a flat, level flight to maximum range, and it holds position in normal use.

Is it hard to fit?

Fitting means splitting the gun, so if you are not confident stripping the receiver our in-house team can do it for you through our Kent repair service.
