Okay, so I'm trying to make a double plunger tube rainbow pistol

My plan is just a y pvc joint for a barrel to plunger thing

the a weird system with some upside down catches to get one pull to release at the same time 

My hope is that I can get a full seal (no anti-vacuum loading holes) and to use doubled [k26] in each plunger tube. 

So any thoughts, sincerely

Did you know that the nerf sharpfire can take like a 10kg retaliator spring with a decent amount of stress on the internals, not sure how long it lasts because the blaster makes a not good sound when fired. I used full lengths and got decent range with no rebarrel but brass whould help. fits nicely in a VISM ncstar camo side pouch good for last ditch sidearm.
