Custom Piece – M4 carbine with a URG I Upper Receiver Group Improved AR-15 pattern rifle – 3D Print for LEGO minifigure

A model of an AR-15 pattern rifle, specifically configured as a military-style carbine. It features:

• A telescopic sight (scope) mounted on the top Picatinny rail.
• A tactical foregrip attached to the handguard.
• A specialized handguard, which appears to be an M-LOK or similar modern rail system, consistent with a URG-I (Upper Receiver Group – Improved) upgrade.
• A customized muzzle device.
• A collapsible stock.

Based on the visual cues and the “URGI” in the filename, this is a miniature replica of an M4 carbine with a URG-I (Upper Receiver Group – Improved). The URG-I is an upgrade for the M4A1 carbine used by US Special Operations Forces, featuring a Geissele Super Modular Rail (SMR) and other enhancements.
