Custom Piece Miniature – M4A1 carbine equipped with a holographic sight and a suppressor – 3D Print for LEGO minifigure

This is a Lego minifigure accessory.

The item depicted in the image is a toy model of an M4A1 carbine equipped with a holographic sight, a vertical foregrip, and a suppressor (silencer), designed for Lego minifigures.

These kinds of detailed accessories are typically not official Lego Group products but are created by third-party companies specializing in custom Lego-compatible elements, particularly for military or action themes.

Based on the image and the Chinese text in the filename “M4A1 全息消音” (M4A1 quán xī xiāoyīn), which translates to “M4A1 holographic sight suppressor,” the item can be described as:

• An M4A1 carbine variant with a holographic sight and a suppressor.

While there isn’t a universal official “model number” for such custom accessories in the same way official Lego parts have, it would be identified by sellers or manufacturers using descriptive terms like the one above, or a specific product code from that particular custom brick vendor. The “SKU-11-603” in the filename is likely a stock-keeping unit number specific to the seller or manufacturer of this accessory.
