Description
Emerson CNC Magazine Catch for AEG M4 (Blue)
The Emerson CNC Magazine Catch is a machined replacement magazine catch for M4-pattern electric rifles. Our listing names the colour as “lue”, which we read as blue; please check the product images to confirm the finish before ordering. A coloured catch is one of the simplest ways to add a custom accent to the side of an M4 lower receiver.
Emerson (Emersongear) is best known for tactical clothing and load-bearing gear, and also supplies small parts and accessories for popular replicas. This catch suits M4 AEG owners who want a two-tone or themed custom build, and anyone replacing a worn, loose or damaged factory catch with a CNC-machined part.
What it does
The magazine catch holds the magazine in the magwell and releases it when you press the button on the right of the receiver. A precise catch helps magazines seat and lock consistently, which matters when you are reloading quickly under pressure.
Because the catch button is one of the most visible controls on an M4, a coloured one stands out well against a black, grey or tan receiver and can be matched with other coloured small parts such as a selector lever or charging handle.
Fitting
Our listing describes this catch as for M4 AEGs. Catches can still vary slightly between makers, so compare the part in the images with the one in your rifle before ordering. Remove the battery and magazine first, follow your replica’s manual and test with an empty magazine that it locks firmly and releases cleanly before loading BBs. If you are not confident, ask an experienced technician to fit it.

Compatibility
Listed for M4-pattern AEGs. It is not intended for gas blowback rifles, and fit can vary between manufacturers, so compare it with your existing catch or ask us before buying. It does not change which magazines your rifle accepts.
Care and maintenance
Keep the part and the area around it free of grit, which can make controls stiff or stop them working cleanly. Wipe it over after a muddy or wet game and let the replica dry before casing it.
A very light touch of silicone oil on moving parts keeps the action smooth. Avoid harsh solvents, which can mark coloured and anodised finishes, and check now and then that the part is still secure.
Who is it for?
This catch suits M4 AEG owners building a custom or colour-themed rifle, and anyone who wants to replace a worn factory catch with a precise CNC part.
Please note: The replica and magazine are not included. Fitting may need some technical knowledge; if in doubt, ask a technician.
