Building A Better Bullpup (work in progress):Build-log here: www.tapatalk.com/groups/britne… Trying to address all that is wrong with the Rayven...* Full Auto rather than semi-auto (Rapidstrike pusher-box).* Fire-control: 16amp micro-switch with short and responsive pull rather than janky manual trigger.* Wiring: 16AWG. Bullpup layout allows very short uncomplicated run: battery>switchgear>motors>return via thumb-hole bottom bracket* Artifact Red flywheel cage: drops in solidly onto three of the four attachment points. Minor bodywork needed to achieve screw-down on fourth.* Flywheels: Worker serrated concave Rapidstrike* Motors: TBA* Stock: Cut-down Rapidstrike. Taller and longer reach than Rayven. May lengthen reach again slightly for better 1-handed firing.* Magazine housing and alignment: rock-solid* Mag-release: to be extended using RS stock locking-switch.* Flywheel motors on opposite side of shell to operator's ear.* Vibration damping: glued between shell layers.* Handgrip: currently a Firestrike, but will bite the bullet and cut up a Stampede to use it's grip/thumb-hole combo.* Battery: grip-mounted power-tool-style battery. Option of using stock Dewalt 2Ahr '12vMAX' (3S 18650) battery packs or custom packs running 2x18650 (Samsung 25r) drop-in's or 2S/3S Lipo (requires shell-work on stock battery packs...).* Balance: as much weight low and to the front as possible.* Thumb-hole: Keeping it. Demo mag well is very wide at base so hand-grip connecting-bar guides wrist away from there.* Barrel-length: without Stampede flash-supressor, shorter than the Rayven by about 40mm.* Over-all length: without Stampede flash-supressor, again shorter than the Rayven.
