Frequently Asked Questions

What is the main advantage of mounting optics to the chassis instead of the slide on pistol conversion systems?

Mounting optics directly to the chassis, as seen in the Flux Raider and B&T USW-G, prevents the optic from reciprocating with the slide. This significantly improves red dot tracking and sight stability, leading to more consistent accuracy during rapid fire.

What are the key legal differences between the Flux Raider and the B&T USW-G?

The B&T USW-G is configured as a Short Barreled Rifle (SBR) and requires a federal NFA tax stamp. The Flux Raider is designed as a braced pistol, which, at the time of this video, does not require an NFA tax stamp, making it a more accessible option for many users.

How does the Flux Raider's magazine release system work?

The Flux Raider features an innovative dual-magazine release. A partial press of the lever releases only the front magazine, while a full, deliberate press releases both magazines simultaneously, allowing for extremely fast reloads.

Which pistol platforms are compatible with the Flux Raider and B&T USW-G chassis?

The Flux Raider is designed specifically for the Sig Sauer P320, M17, and M18 pistol series. The B&T USW-G is compatible with Glock models 17, 19, 22, 23, 31, and 32, specifically Gen 3 through Gen 5.
