Custom Piece Miniature – M4 carbine equipped with a URGI Upper Receiver Group – Improved and a Trijicon ACOG Advanced Combat Optical Gunsight – 3D Print for LEGO minifigure

This is a Lego minifigure accessory.

The item in the image is a toy rifle designed to be compatible with Lego minifigures. Based on its visual characteristics and the highly descriptive filename “URGI ACOG,” this accessory represents an M4 carbine equipped with a URGI (Upper Receiver Group – Improved) and a Trijicon ACOG (Advanced Combat Optical Gunsight).

Key features visible that support this identification are:

• The overall M4/AR-15 platform.
• A modern M-LOK style handguard, consistent with the Geissele MK16 rail used on URGI setups.
• An optic that resembles an ACOG.
• The presence of a suppressor.
• What appears to be a top-mounted laser aiming module (like a PEQ box).
• A standard carbine stock.

The URGI is an upgrade for the M4A1 carbine used by U.S. Special Operations Command (USSOCOM).

Therefore, you can describe this item as: “A Lego minifigure accessory representing an M4 carbine with a URGI (Upper Receiver Group – Improved), ACOG sight, suppressor, and laser module.”
