Turn Your P320 into an SBR: Flux Raider — SHOT Show 2023

Flux Defense decided you need a brace for your P320, giving you a concealable short-barreled rifle. Their Raider is a new grip module that gives you a quick-deploying brace and a larger frame for better accuracy.

The Flux Raider is compact and adds functionality to your P320 pistol.
This lever at the top deploys the spring-loaded brace.

With the flick of a lever, the brace shoots out and locks in place. Although the brace was not intended to be shouldered, with the new ATF rule this will be classified as an SBR so you might as well shoulder it, after you fill out the relevant forms and pay the tax stamp, of course.

The chassis adds an AR-like safety switch. It also adds a magazine holder in front of the trigger guard.

Sliding this button forward drops the mag from the grip and drops the spare mag from the forward mag holder.

This mag holder is cool because it drops the extra mag when you drop the mag that is in the grip. This is a very fast way to switch magazines and the flared mag well helps, too.

The brace shoots out and locks in place immediately and rigidly.
The chassis provides a higher optics mount.

The chassis also adds a high optics mount and a rail under the barrel for lights.

    This company is great at engineering an excellent chassis, but horrible at making them available. I have been on a waiting list for 2 years, and while i used tto get updates when they would be available(sold out in minutes), I havent heard anything for a long time.

      You’re not wrong. We made horrible choices on who to produce the parts, but have been working the last year to correct those mistakes. We now have multiple sources for the frames, and should be able to produce 20,000 this year, at least. Hope you are able to get one. 🤙
