This is the MKII release of THE SCATTERSHOT, a foam dart launching, pump action, Spring powered, 3d printed blaster. It fires 3 half darts per shot in a 3 degree spread, is fed from an under slung horizontal box magazine and has a 12 + 1 shot capacity. Read the included build guide thoroughly before attempting to make this.
The changes made to the MKII are
- Slight improvements to the overall aesthetics and some additional detailing
- Redesigned the internals for a larger, more widely available plunger tube
- Made printable alternatives to the two other sizes of PVC pipe used in the build
- Improved the breach hinge
- Some changes have been made to the required hardware, see the build guide for the updated list

To operate the blaster, load the magazine with up to 12 darts per stack, then, with the pump in the forward position insert the magazine by pushing it up and forward into the magwell till it catches in place, the darts must be facing up. then prime the blaster by pulling the pump back all the way till the trigger catches then all the way forward in one swift smooth motion, the blaster is now ready to fire, half priming and slow priming will more than likely jam the blaster. To remove the magazine, push the mag release button in the trigger guard and pull down on the magazine. In order to help prevent dry firing, the blaster will not prime when the magazine is empty. Do not dry fire the blaster, or fire it when the pump grip is not in the forward position, as will more than likely damage the blaster.
I have successfully tried springs up to 12 KG, I don't how much higher of a spring load the blaster can take. I recommend using a 10 kg spring.
The Blaster is loud so I recommend wearing ear plugs when firing it. To avoid potential injury, be sure to wear safety glasses and all other appropriate safety equipment when making and using this blaster.
Thanks to MeakerVI for his work which led to the PVC plunger pipe replacement https://www.thingiverse.com/MeakerVI/about
