NERF MOD: Nerf Rival Proton Pack (270 Ball Capacity Full-Auto!)

I was going to post this in a few weeks, but decided to post it early! This is my new original design, a "Nerf Rival Proton Pack." It's full-auto, holds 270+ rounds. Updated Version 2.0 here (500 balls and no coil of hose)!!!    • MOD: Highest capacity Nerf blaster ever! 5...   This video shows a prototype only, not final design! Link to Final Design:    • NERF MOD: Tactical Proton Pack (1150 rounds!)   Final Design Build-it-Yourself Kit Available Here: https://outofdarts.com/products/proto... Note: I only had 270 rounds to test with, otherwise I'd fill the hopper with another 60 balls. The hopper feeds the blaster automatically and is fed by air and agitation while moving around with the pack on your back. PARTS LIST: Same parts at Nerf Rival 5600, video with list coming tomorrow! ALSO USED: A hopper (cut and widened for HIR's): http://www.amazon.com/Empire-Paintbal... 20' of washing machine hose (Cut and taped together): http://www.homedepot.com/p/Everbilt-5...
