I tried a few different ideas before I built this and read some threads by others who had tried it. The issue with firing more than 1 bb from a single barrel is if its all on one cycle then theres the very real possibility its gonna jam all the time. A 3-5 rnd burst might work but it gets complicated and expensive at that point buying new gearsets and delayers etc.

The inner dimensions of the 12 gauge sized outer barrel is enough to accommodate the tri-shot system but a whole new gearbox would have to be built shell up.
