<\/span>One of the really cool things about dropping a Retro Arms gearbox into a VFC SCAR receiver is that with a couple of small modifications you can have a true quick-change spring with ZERO removal of the gearbox required.<\/p>\n

Installing the Retro Arms CNC gearbox shell requires a modification to the lower receiver to allow it to sit level – basically the removal of about a 1\/2″ of polymer material (a “shelf” if you will) from inside the magazine well.<\/p>\n

I ultimately decided not to drop a MOSFET into this gearbox since I wanted to retain the ability to remove the lower and not have any ugly wires snaking through the buttstock hinge area (which also creates a potential pinch point). So I removed all of the stock wiring harness, as well as gutted the wiring from the buttstock and ditched the fuse. I rewired the entire thing with 16 gauge Deans ultra-wire and reused the VFC contact pins and electrical contact hardware in the stock. Overall it makes for a really clean look; and coupled with the high speed gearset and the Systema Magnum motor it has excellent trigger response.\u00a0 <\/span><\/p>\n
