Custom Piece – Short Barreled Rifle SBR AR-15 M4 rifle – 3D Print for LEGO minifigure

the items in the image are:

• A miniature assault rifle: This appears to be modeled after a Short Barreled Rifle (SBR) variant of an AR-15 or M4 style rifle.
• Scope: A toy telescopic sight is mounted on top of the rifle.
• Suppressor: A mock suppressor is attached to the muzzle of the rifle.
• Magazine: A miniature magazine is inserted into the rifle.
• Foregrip: A small vertical foregrip is attached to the handguard.

Specifically, this is a toy or replica of a customized Short Barreled Rifle (SBR), likely based on an AR-15 or M4 platform, outfitted with common tactical accessories, and intended for use with minifigures. The initial suggestion of “7.5 ar10” might be inaccurate, as the visual characteristics and its nature as a minifigure accessory point more towards an AR-15/M4 pattern.
