Assembly Instructions: http://www.captainslug.com/nerf/R3Assembly1.pdf Hardware Kit: https://www.etsy.com/listing/741550256/ This is essentially the inline Rival Mag system adapted from the FLAK into the Rivalburn U, but upgraded a little bit to add compatibility with the Worker 15rd Rival Mags that otherwise don't work in anything except the Hera. The foregrip actuates an elevator that presses the magazine detent, causing it to eject a Rival round onto the elevator. When the foregrip goes forward the spring return on the elevator pops the HIR up into the path of the Ramrod, and it then gets pushed into the barrel. The top of the magwell has a hole to allow a +1 HIR to be loaded ahead of the elevator output so you can add HIRs in tandem without feeding from the magazine. This can be done whether the mag is full, empty, or even absent. Behind the +1 port is the sliding jam door port which allows you to ramrod out and then dump an uncooperative HIR. The port in the bottom of the magwell allows the magazine to be loaded by hand when the breech is closed without having to remove it from the blaster. The magwell accepts 15, 12, and 7 round Rival mags. Blaster is compatible with the 788, K25, and K26 springs. Adjustable hop-up at the muzzle is a 4-40 screw driven in at an angle.
