Frequently Asked Questions

What is the Flux Raider SBR?

The Flux Raider SBR is a polymer chassis system designed for the Sig P320 platform. It allows users to build a Short Barreled Rifle (SBR) or Pistol Caliber Carbine (PCC) that resembles an SMG, using their P320's Fire Control Unit (FCU) and slide.

How does the Flux Raider SBR reload?

It features a unique dual magazine system with three release buttons, enabling a fast, intuitive 'fist-to-fist' reloading technique similar to an Uzi, which is highly effective in low-visibility conditions.

What are the dimensions and weight of the Flux Raider SBR?

The chassis alone weighs 18 oz. When assembled with a P320, it measures 11 inches long collapsed and weighs approximately 40-47 oz. It is significantly thinner and lighter than comparable firearms like the H&K MP5K PDW.

Is the Flux Raider SBR considered accurate?

Yes, range testing at 40 feet showed excellent accuracy with tight groups, even during rapid fire. The non-reciprocating optic mount contributes to a stable aiming point compared to traditional slide-mounted pistol optics.
