Assembly instructions:

https://youtu.be/-Rf9GtquNHU?si=8-30qUi31-80FlHQ

Supports are needed only for your neck of choice, the knob and the fan. every part is preoriented.

DISCLAIMER: Some slicers will auto orient the neck so it stands up. we have found it to be more reliable with the “kptnautismus” inscription facing downwards.

you choose the neck based on how far your magazine is sticking out, you measure it by sticking a talon mag into your blaster, marking where the blaster stops and measure the length of the inserted part of the magazine (minus the feed lips). now choose the closest size that is larger than your measurement. 

you'll need extra dummies too.

the 55mm neck takes 3 dummies.
the 90mm neck takes 4 dummies.
the 130mm neck takes 5 dummies.
the 165mm neck takes 6 dummies.
the 200mm neck takes 7 dummies.

Credit to atlasunit22 who helped me develop this drum and even had the ideas for the ratchet knob and the bearings.

further credit goes to many other members of the BCFF Discord for printing it and giving feedback during beta.

Compatibility:

It likes blasters better in the following order: Springers>motorized pusher>solenoid>AEB
the shorter the bolt stays open the less time the drum has to push another dart in.
