This realistic 3D model of a tactical stock inspired by HK designs is built as a Bluegun-style inert replica — perfect for training setups, cosplay builds, or display use.
Its geometry has been optimized for ease of 3D printing while preserving accurate external proportions for gear fitting and mock-up purposes. For the pin use 1.75mm filament.

🛠 Model details:
• Life-size 1:1 scale design
• Fixed one-piece body (no moving parts)
• Separate buttpad (plaque de couche) file for flexible printing
• Compatible with standard mil-spec buffer tube profiles
• Clean STL files optimized for FDM printing

🎯 Ideal for:
• Tactical or police training scenarios
• Mock rifle builds and inert setups
• Cosplay and movie props
• Display and collection
• Gear layout testing with vests, slings, etc.

🧵 Recommended materials:
• PLA, PETG, ABS for the main stock
• TPU (flexible filament) strongly recommended for the buttpad to replicate rubber-like feel and improve comfort

⚠ This is a non-functional and non-adjustable replica.
It does not contain any working mechanisms or moving parts.
