SHS Reinforced Selector Plate — Version 2 Gearbox

The selector plate is the thin moulded part that rides against the cut-off lever and trigger contacts, translating the position of your fire selector into what the gearbox actually does. It takes constant rubbing and it is almost always plastic, so it is one of the first things to wear out in a well-used AEG. The symptom is familiar: the selector feels vague, semi starts doubling, or the gun refuses to leave safe.

SHS build affordable internal components for AEGs, and this is the plain reinforced version of their Version 2 plate — a straight replacement in high-grade polymer rather than a performance part. It fits most Version 2 series metal gearboxes. Version 2 shells do vary between manufacturers, so it is worth comparing the old plate against the new one before reassembly.

It is a job worth doing while the shell is already open. If you are in there replacing a spring, a piston or a set of contacts, a fresh selector plate costs almost nothing and saves stripping the gearbox again in six months.

Specifications

Good to know before you buy

This is the standard reinforced plate, not a low-resistance or performance part — it restores correct selector function rather than changing trigger behaviour. Fitting means opening the gearbox, so it is a bench job rather than a field fix. Everything else for that job sits in our gearbox parts range.

Frequently asked questions

How do I know the selector plate is what has failed?
Typical signs are a selector that will not hold position, a gun that fires in the wrong mode, or one that stays on safe. Those symptoms can also come from a worn detent or the cut-off lever, so inspect all three once the shell is open.

Will it fit my gearbox?
It suits most Version 2 series metal gearboxes. Version 2 shells differ slightly between manufacturers, so lay the old plate on the new one and check the cutouts line up before you build the shell back up.

Is it the same as the low-resistance plate?
No. This is the standard reinforced plate. The low-resistance version is a separate SHS part aimed at trigger response rather than replacement.

Does fitting one need any special tools?
Only what a gearbox strip already needs — the plate itself drops into place once the shell is apart. If you would rather not open the gearbox yourself, have a local AEG tech fit it.
