The SMILEY is a 3D-printed bolt-action springer designed by Mighty Shrub, heavily remixed from the yet-to-be-released MHP Wrenfield MK-3. Featuring a slim-angled "Nightingale" magwell and plunger-in-grip design, this blaster packs quite a bit of power in its compact form factor. Additionally, the Smiley features toolless spring and barrel swaps for customizable FPS on the go. 

This hardware kit includes everything you need to print the 3D parts and assemble this blaster yourself with Sillybutt's O-ring breech remix (3D files available below).
