Custom Piece Miniature – Mk 14 Enhanced Battle Rifle EBR – 3D Print for LEGO minifigure

Here’s why it appears to be an Mk 14 EBR rather than an M4:

• Receiver and Chassis: The overall body shape, particularly the chassis system, the larger receiver, and the magazine well, are characteristic of the Mk 14 EBR.
• Magazine: The magazine is larger and boxier, consistent with the 7.62x51mm rounds used by the M14 platform, rather than the smaller, often curved magazine of an M4 (which uses 5.56mm rounds).
• Stock: It features a telescoping stock often seen on EBR variants.
• Optic: It is equipped with a scope, suitable for the designated marksman role the Mk 14 EBR often fulfills.
• Handguard: The railed handguard style is also in line with modern Mk 14 EBR configurations.
• Muzzle Device: It has a distinct muzzle device.

While the filename mentioned “M4,” the visual characteristics of the toy firearm align much more closely with the Mk 14 Enhanced Battle Rifle. The “瞄准” (aiming) part of the filename likely refers to the presence of the scope.

In English, you would describe this as: “A LEGO minifigure accessory depicting an Mk 14 Enhanced Battle Rifle (EBR) with a scope and a foregrip.”
