The original. No stock, stubbed barrel.
A 3D-printed HPA competition airsoft gun in a stubbed-AR / comp-pistol form factor. Single-solenoid engine, tuned by hand to run lower pressure than the competition — quieter, more air-efficient, and dead accurate. Ships fully assembled.

The tougher material, and the better one outdoors — it holds up to heat and takes an impact far better than PLA+. Our standard. Covers 14 of our 17 colours.

Chronographed on our own bench. Every figure is a 5-shot average with 0.25 g BBs through a 4" barrel.
