Custom Piece Miniature – SIG Sauer XM5 XM7 MCX Spear rifle equipped with a suppressor – 3D Print for LEGO minifigure

However, we can interpret the item based on the descriptive filename “SIGM5 无配件”:

• SIGM5: As with the previous item, this likely refers to a SIG Sauer firearm. It’s highly probable this is intended to represent the SIG Sauer XM5 (which was later designated the XM7), the rifle selected by the U.S. Army as part of the Next Generation Squad Weapon (NGSW) program, based on the SIG MCX Spear.
• 无配件 (wú pèijiàn): This translates to “no accessories” or “without accessories.” This suggests the Lego piece represents the rifle in a more basic or stripped-down configuration, without additional optics, suppressors, or other attachments that might be featured on other versions. It would represent the fundamental shape and design of the rifle itself.

Therefore, the item is intended to be a Lego minifigure accessory representing a SIG Sauer XM5 / XM7 (MCX Spear) rifle in its basic configuration, without additional specialized accessories.

In English, you would describe this item as: “A Lego minifigure accessory representing a SIG Sauer XM5 / XM7 (MCX Spear) rifle in a basic configuration without additional accessories.”
