A replacement for the original System 7 outer barrel and hop-up which allows the fitting of standard AEG inner barrels and hop-up rubbers. System 7 parts are hard to come by these days and this allows you to upgrade and uprate your inner barrel with the hop-up rubber of your choice. Features a novel rotary adjustable hop system and a selection of different strength nubs so you can hop whatever weight of BB you need to. Alternately there is a TDC version, adjustable by hex key, but to adjust it in-situ you need to drill through the bolt and upper receiver. Printed from super tough Black ABS lik

Where this comes from

The part other shops don't tell you. Three separate questions, kept separate on purpose, each with its source.

UK company
Registered at Companies House as AMETHYST ARTIFICERY LIMITED, number 16730034. Checked 2026-08-29.
Means the business is a British legal entity, not a British-sounding name owned elsewhere. It says nothing about where anything is made.
UK operations
Not yet checked.
Means people employed here, or premises they actually work from. We keep this separate from the company badge because a registered office can be an accountant's spare room, and a company can be registered in Britain while everything it does happens somewhere else. Where we have not looked, we say so rather than assuming.
British-owned
No majority shareholding traced outside the UK. Companies House.
Read from the register of people with significant control, following the chain of holding companies. It does not gate anything: a firm can be made here and owned elsewhere, and that is worth telling you rather than hiding.
Where it is made
The maker doesn't say, so neither do we.
This is about the individual product, not the company. A British firm can sell things made abroad, which is normal and not a criticism. We would rather tell you which is which than average them into a score.
