Fire Selectors

The Fire Selector is the external control that allows you to select the firing mode on your airsoft replica. Depending on the platform, this allows you to switch between Safe, Semi-Auto and Full-Auto. A properly functioning fire selector ensures distinct click positions, smooth operation and reliable switching between the different firing modes.

Why choose a high-quality Fire Selector?

A high-quality fire selector ensures that the selected firing mode is engaged clearly and reliably. Furthermore, a precision-finished selector contributes to smooth operation and a high-quality finish on the replica.

By choosing a high-quality fire selector, you’ll benefit from smooth operation, distinct click positions and reliable performance during every skirmish.

What exactly does a Fire Selector do?

The Fire Selector acts as the link between the user and the replica’s internal selection mechanism. When you turn the selector, this movement is transmitted to the Selector Plate in the gearbox. Depending on the position selected, this determines whether the replica operates in Safe, Semi-Auto or Full-Auto mode.

Although the fire selector itself is an external component, it works in close conjunction with the internal parts of the gearbox. A precise fit and correct assembly are therefore essential to ensure that each fire mode is selected correctly.

How does a Fire Selector work?

Although operating a fire selector seems simple, there is more going on internally than many players realise. As soon as you turn the selector, this movement is transmitted via the selector assembly to the selector plate. The selector plate then determines which fire mode is active and how the gearbox’s internal switching mechanism responds.

In replicas with a mechanical trigger, this is done entirely mechanically. If the replica is fitted with an ETU or MOSFET, the electronics detect the position of the selector and adjust the replica’s operation accordingly.

That is precisely why a well-fitting fire selector is important. Not only for ease of use, but also to ensure that each fire mode is selected correctly and reliably.

Ambidextrous Fire Selectors

An Ambidextrous Fire Selector is fitted with a selector lever on both the left and right sides of the receiver. This allows both left- and right-handed players to quickly adjust the fire mode without changing their shooting stance.

As well as offering greater ease of use, ambidextrous selectors are also popular in professional and realistic builds. As they can be operated from either side, they are better suited to modern AR platforms, where dual-sided operation is increasingly becoming the norm.

Why does a Fire Selector wear out?

A fire selector is operated dozens, and sometimes even hundreds, of times during every skirmish. As a result, prolonged use can lead to wear and tear or minor damage to the selector itself or to the associated mounting parts.

Common causes of wear and tear include:

• Intensive use during skirmishes.
• Loose fixing screws.
• Wear and tear on the selector assembly.
• Damage caused by a fall or impact.
• Dismantling during maintenance or upgrades.

If a fire selector starts to develop increasing play or the fire modes become less distinct, it is advisable to check both the selector and the underlying structure.

Why does a Fire Selector have click positions?

When you turn the fire selector, you can feel distinct clicks between Safe, Semi-Auto and Full-Auto. These clicks are caused by a detent and a small spring, which ensure that the selector remains firmly in the selected position.

This prevents the fire selector from accidentally changing fire modes whilst in use. If, on the other hand, the fire selector feels very loose or does not stay in position properly, this is often caused by a worn detent, a damaged spring or wear and tear on the selector itself.

Top brands within Fire Selectors

In this category, you’ll find fire selectors from manufacturers renowned for their reliable quality and precise fit.

Guarder has been manufacturing high-quality external parts for M4 platforms for many years and is renowned for its solid workmanship. G&G supplies reliable replacement parts for various AEG platforms, whilst Krytac offers, in addition to standard versions, a high-quality Ambidextrous Fire Selector for players seeking maximum control and ease of use.

Practical tip

After fitting a new fire selector, always check that Safe, Semi-Auto and Full-Auto are selected correctly before fully assembling the replica. This will prevent you from having to open the gearbox again later to adjust the selector mechanism.

Professional use

In professional maintenance and custom build projects, a fire selector is checked not only for wear and tear, but also to ensure it operates correctly with the selector plate and the internal switching mechanism.

After assembly, experienced airsoft technicians test each fire mode individually to check that the selector switches smoothly, has distinct click positions and correctly transmits the selected fire mode to the gearbox. It is precisely this check that prevents malfunctions and ensures reliable operation whilst playing.

What should you look out for when buying a Fire Selector?

Before you buy a new fire selector, it is important to check which model is suitable for your replica.

In this regard, please bear in mind the following, amongst other things:

• Compatibility with your platform (M4 or MP5).
• Standard or ambidextrous version.
• Compatibility with your receiver and selector assembly.
• The quality of the finish and the dimensions.
• Compatibility with any aftermarket parts.

By selecting the correct fire selector in advance, you ensure reliable operation and that all available firing modes function correctly.

Fire Selectors within AEG External Components

The fire selector acts as the link between the user and the replica’s internal selection mechanism. By selecting the desired firing mode, the selector plate determines whether the replica is in Safe, Semi-Auto or Full-Auto mode. A properly functioning fire selector ensures clear operation and reliable selection of each firing mode.

Are you in the process of maintaining or upgrading the exterior of your replica? If so, be sure to check out our AEG External Parts category, where you’ll find all the parts you need for maintenance, repairs and complete custom builds.

Common mistakes

Although a fire selector may seem simple, minor assembly errors can prevent the replica from switching correctly between the different firing modes.

Common mistakes include:

• Fitting a Fire Selector without checking that the Selector Plate is working properly.
• Choosing a selector that is not suitable for the correct platform, such as the M4 or MP5.
• The fixing screw is not tightened sufficiently, causing the selector to rattle.
• Assuming that a replica that shifts poorly is always caused by the fire selector, when the cause could also lie with the gearbox or selector plate.
• Do not check whether the Safe, Semi-Auto and Full-Auto modes are actually working correctly after assembly.

By carefully testing all firing modes after each assembly, you can avoid having to dismantle the replica again.

Frequently Asked Questions about Fire Selectors

What exactly does a fire selector do?
The fire selector is the external control used to switch between the replica’s different firing modes. This movement is transmitted via the selector mechanism to the selector plate in the gearbox.

Why does my fire selector feel loose?
A fire selector that feels loose or wobbly is often caused by a worn detent, a damaged spring or a loose fixing screw. Check these parts before replacing the fire selector.

What is an ambidextrous fire selector?
An ambidextrous fire selector can be operated from either side of the replica. This offers added ease of use for both left- and right-handed players and makes changing the fire mode quicker and more intuitive.

Does every Fire Selector fit every M4?
Not always. Although many M4 platforms use similar mounting points, dimensions and construction may vary from one manufacturer to another. You should therefore always check compatibility with your replica.

Does a fire selector affect the performance of my AEG?
No. A fire selector does not increase the FPS, accuracy or rate of fire. Its function is to reliably select the desired firing mode and to correctly control the internal selection mechanism.
