Custom Piece – Heckler & Koch HK416C carbine – 3D Print for LEGO minifigure

The item in the picture is a minifigure-scale toy Heckler & Koch HK416C compact carbine or personal defense weapon (PDW) accessory.

Specifically, it’s a miniature plastic replica of a very compact assault rifle, designed for toy figures (“minifigures”). It features:

• An AR-15 style receiver (characteristic of the HK416 family)
• A very short, collapsible wire-frame style stock (a distinctive feature of the HK416C)
• A short handguard and barrel
• An AR-15 style magazine
• Iron sights (front and rear)
• An ergonomic pistol grip

2. What specific gun it is:

This toy rifle is designed to represent a Heckler & Koch HK416C.

Here’s why:

• Filename Indication: The filename “▲HK416C” directly points to this specific model.
• Distinctive HK416C Stock: The most telling visual feature is the stock. The toy clearly replicates the unique, ultra-compact, retractable two-strut wire stock that is specific to the HK416C variant. This is very different from standard M4 stocks or other common AR-15 stocks.
• Compact Dimensions: The overall proportions, including the very short barrel and handguard, are consistent with the HK416C, which is designed as a compact weapon for close-quarters battle (CQB) or as a personal defense weapon.
• HK416 Features: While it’s a toy, it generally captures the look of the HK416 platform, which is an AR-15 derivative. This includes the upper and lower receiver style, magazine, and pistol grip. The metadata hint “M4 carbine” is relevant because the HK416 is an improved version of the M4.
• Iron Sights: The presence of what appears to be HK-style diopter iron sights (or at least compact iron sights) is also fitting.

The other metadata hint, “sig cqb,” refers to compact rifles made by SIG Sauer. While those are also AR-style CQB weapons, the stock on this toy is a much more direct match for the HK416C than for typical SIG offerings.

In summary: This is a toy carbine accessory for minifigures, and it is clearly modeled to look like the Heckler & Koch HK416C, primarily identifiable by its unique compact stock and overall very short configuration.
