Custom Piece Miniature – HK416 assault rifle with an ACOG-style optic – 3D Print for LEGO minifigure

Based on the image, the item is a toy rifle with an optic and a vertical foregrip, designed for LEGO minifigures.

Looking at the details, this miniature rifle strongly resembles an HK416. The filename “SKU-78-▲HK416DACOG.webp” is a big clue. Key features that point to an HK416 (or a very similar AR-15 derivative like an M4 carbine) are:

• The distinctive handguard.
• The style of the buttstock.
• The pistol grip.
• The presence of an ACOG-style (Advanced Combat Optical Gunsight) optic, as hinted by “ACOG” in the filename.
• The vertical foregrip.

So, in English, you could describe it as:

• “A LEGO minifigure compatible toy model of an HK416 rifle with an ACOG-style optic and vertical foregrip.”
• “A miniature HK416 assault rifle accessory for LEGO figures.”

The specific firearm it appears to be modeled after is an HK416 assault rifle, likely configured with an ACOG sight and a vertical grip. The “M4 carbine” and “Colt C8 Canada” mentions in the image metadata are related, as the HK416 is an improved version of the M4 carbine, and the Colt C8 is a Canadian variant of the M4 platform. However, the specific visual cues, especially if “HK416” is in the filename, lean more towards the HK416.
