Custom Piece – Heckler & Koch M320 Grenade Launcher – 3D Print for LEGO minifigure

The item in the picture is a minifigure-scale toy M320 Grenade Launcher.

Specifically, it’s a miniature plastic replica of a modern single-shot grenade launcher, designed for toy figures (“minifigures”). It appears to be in a standalone configuration and features:

• A short, large-caliber barrel (for 40mm grenades in the real weapon)
• A pistol grip
• A vertical foregrip
• A compact, possibly collapsible or folding, stock
• A top-mounted sight (representing the M320’s sighting system)

2. What specific “gun” (grenade launcher) it is:

This toy is designed to represent the Heckler & Koch M320 Grenade Launcher Module (GLM), shown here in its standalone configuration.

Here’s why:

• Filename and Metadata Indication: The filename “▲M320榴弹” (M320 Grenade) and the image metadata “m320 png” directly identify it as an M320.
• Distinctive M320 Features:
  • Side-Opening Barrel: The M320 is known for its barrel that swings open to the side (typically to the left) for loading. While not fully open in the image, the barrel’s design and slight parting suggest this mechanism, distinguishing it from older underbarrel grenade launchers like the M203 (which has a slide-forward barrel).
  • Standalone Configuration: The M320 can be used as a standalone weapon with its own stock and grip module (as depicted by the toy with its pistol grip, foregrip, and compact stock element) or mounted under a rifle.
  • Sighting System: The blocky sight on top is representative of the leaf sight or more advanced sighting systems used on the M320.
  • Overall Modern Look: The general ergonomics and design are consistent with the H&K M320.

The M320 is the U.S. military’s replacement for the M203 grenade launcher.

In summary: This is a toy grenade launcher accessory for minifigures, and it is clearly modeled to look like the Heckler & Koch M320 Grenade Launcher in its standalone setup.
