Custom Piece – M4 carbine with a URG I type handguard and a magnified optic setup – 3D Print for LEGO minifigure

an M4 carbine equipped with a URG-I (Upper Receiver Group – Improved) style handguard and a magnified optic, possibly with a mini red dot sight mounted on top or offset. It also features a vertical foregrip and a muzzle device that could be a flash hider or a compact suppressor.

Here’s a breakdown of its features:

• URG-I Style Handguard: The rifle features an M-LOK handguard that is characteristic of the URG-I (Upper Receiver Group – Improved), which is an upgrade for M4 carbines.
• Magnified Optic with Possible Mini Red Dot: There’s a primary telescopic sight (scope) mounted, and it looks like there might be a smaller red dot sight mounted on top or to the side of the main optic. This is a common setup for versatile engagement ranges. The “HS6” in the filename might hint at a specific optic model or configuration, but visually it’s a scope with a potential secondary red dot.
• Muzzle Device: It has a muzzle device, which could be an advanced flash hider or a small suppressor.
• Stock: It features a modern, adjustable carbine stock.
• Grip: It has a vertical foregrip for better weapon control.
• Accessories: There might be other small accessories like laser/light modules, but they are less distinct.

So, to describe this in English:

“This is a miniature replica of an M4 carbine, likely configured with a URG-I (Upper Receiver Group – Improved) style handguard. It is equipped with a magnified scope that may also have a secondary mini red dot sight, a vertical foregrip, an adjustable stock, and a muzzle device (possibly a flash hider or compact suppressor). This setup is indicative of a modern tactical carbine.”

While the “HS6URGI” designation in the filename strongly points to a URG-I variant, the “HS6” part isn’t a standard or widely recognized military designator for a specific URG-I configuration or optic in the same way “ACOG” is. It might be an internal product code or a reference to a less common commercial optic. However, visually, the firearm is clearly an M4 carbine with a URG-I type handguard and a magnified optic setup.
