The SRP-2 has been released in its first iteration. While being finicky to build and requiring a lot of work to get operating smoothly, it offers an aesthetic and feature set not found in other 3D printable blasters available for free.
The SRP-2 is a flywheeler half dart pistol that accepts straight Talon mags and also has a slide that recoils upon trigger pull. It uses 130 motors and nightingale flywheels, and promises a more engaging pistol experience with FPS upwards of 110.
