Buff Blast FREE – Low Poly Modular Gun Kit, Stylized Pistol and Assault Rifle

One receiver, five parts and a pistol that turns into an assault rifle in a few clicks.

Buff Blast Free is the starter kit of the modular gun pack. We built the whole family around one core receiver that works as a pistol on its own, and every other part is cut to snap onto a socket on it.

The kit ships that core, one part for each attachment slot and both guns assembled from them. A free low poly stylized weapon kit for shooters and party games. It is one of our free Unity assets, with Unreal and FBX versions in the same line.

🔫 WHAT IS INSIDE

• the core receiver, which is also the bare pistol
• an assault front, a curved magazine, a reflex sight, a skeleton stock and an underbarrel foregrip
• the assault rifle and the pistol, assembled as ready prefabs

🧩 HOW IT BUILDS

• one core receiver carries four sockets (front, magazine, top rail, stock) and the underbarrel foregrip attaches to the front part
• every part's pivot sits on its attach point, so it drops in with a zero offset
• the two guns are prefabs built from the same module prefabs, nested inside
• real-world scale: the assault rifle is 90 cm long, the pistol 29 cm, muzzle along +X
• the trigger is a separate mesh with its own pivot, ready to animate

🎮 BUILT FOR ENGINES

• Unity 6: Built-in, URP and HDRP, with an overview scene for each
• Unreal Engine 5.8: overview and display wall maps
• FBX for any other tool

📐 GEOMETRY AND MATERIALS

• 6,974 triangles for the whole kit, from 458 to 2,342 per model
• solid colour PBR materials, no textures to load
• a convex collider on every prefab
