M2 Browning Heavy Machine Gun – Custom 3D Printed Miniature Accessory Parts Pieces for Brick Block Figures

This image shows a LEGO-compatible toy weapon accessory, designed for use with minifigures. It is not an official LEGO product.

The item depicted is a tripod-mounted heavy machine gun.

Key features visible in the image include:

• A long, heavy-style barrel.
• A boxy receiver section.
• Spade grips at the rear for aiming/operating.
• An olive green ammunition box mounted on the left side of the weapon.
• A prominent scope or optical sight mounted on top.
• An olive green tripod mount.

Regarding the “item model” (物品型号): The filename you provided, “SKU-04-M2重机枪1个.webp,” translates from Chinese to “SKU-04-M2 Heavy Machine Gun 1 piece.” This, combined with the visual characteristics, strongly indicates that this toy weapon is modeled after the M2 Browning Heavy Machine Gun.

While your description suggested “lego mk19, M19 Automatic Grenade Launcher,” the visual appearance of this item—particularly its barrel, receiver shape, and spade grips—is more consistent with an M2 heavy machine gun rather than an Mk 19 grenade launcher.

Therefore:

• Product Identifier: “SKU-04” is likely the manufacturer’s or seller’s code for this specific item.
• Represented Model: It is designed to represent an M2 Browning Heavy Machine Gun.
