Custom Piece Miniature – AK 74 assault rifle fitted with an underbarrel grenade launcher – 3D Print for LEGO minifigure

This is a black, AK-74 style assault rifle accessory for LEGO minifigures, equipped with an underbarrel grenade launcher and a top-mounted scope or optic.

Specific firearm: The LEGO accessory represents an AK-74 assault rifle fitted with an underbarrel grenade launcher, likely a GP-25, GP-30, or a similar model. The “AK74” in the filename clearly points to the base rifle, and “榴弹” (grenade) refers to the attached launcher. This configuration is a common setup for this type of rifle. The addition of an optic on the rifle’s dust cover or a special side mount is also a frequent modernization.
