Caliburn: Mag-fed Pump-action Springer

The prototype is finished. I just need to finish testing this over the next few days. A few of you are already aware of this and are working on a 3D-printed version.








Since making the design and making the prototype I've made some small adjustments (not currently pictured). The bolt now seals inside the plunger tube using a skirt seal, just like the plunger head does. The rubber washer was fitting too tight in the plunger tube and made the pump-action too friction heavy.

Photos and videos of the finished blaster will be showing up over the next few days. A write-up may take some time since that requires making another one. I will however make the templates and partlist available once testing is complete.

Special Thanks to skullface44. This design is directly inspired by the Rev-Shot, even if it doesn't really share any dimensions or parts.
