Dust Covers

Dust Covers for a Realistic Finish on your AEG

The AEG dust cover, also known as the ejection port cover, is an external part that covers the opening above the hop-up unit. This part contributes to the realistic appearance of your replica and protects the internal opening from dirt and dust.

Within this category, you will find dust covers from Krytac and VFC, supplemented with models from Balystik. These parts fall under AEG External Parts and are suitable for replacement or cosmetic upgrade of your M4 platform.

What does a dust cover do on an AEG?

• Covers the hop-up opening
• Protects against dust and dirt
• Supports realistic operation
• Improves visual finish

On many M4 AEGs, the dust cover opens automatically when the charging handle is pulled back, providing access to the hop-up adjustment.

For correct operation, the dust cover must be compatible with your upper receiver. The dimensions may vary depending on the brand.

Compatibility and Platform

Important points to consider:

• Suitable for M4 / AR platforms
• Receiver-specific fit
• Compatibility with bolt catch and charging handle
