In this episode of TFBTV, James Reeves reviews the short barrel rifle version of the Flux Defense Raider. The Flux Raider is a chassis system that accepts SIG P320 fire control units and slides to more or less convert it into a pistol caliber carbine or SMG.

From Nick Chen’s article on TFB:

For those of you not familiar with how P320 chassis work, it is all about the genius behind the P320 design. Typical handguns use the frame as the serialized firearm. SIG changed this recipe and registers the Fire Control Unit (FCU) aka trigger module instead of the frame. Since the FCU is the serialized component you can change the frame and even the caliber. While SIG Sauer only offers you the ability to go from full size down to subcompact, it has been third party companies like FLUX Defense to think outside the box and rehouse the FCU into a chassis to give your P320 more features.

That’s cool and all, but is this thing for real? Or just an airsoft range toy? Check today’s video to find out.

      @Biff The paperwork isn't insurmountable, it's the stupid begging for permission for interstate travel.
