Flux Defense Raider 365 Forward Optic Mount – 165-00021

Description

The Flux Defense Raider 365 Forward Optic Mount takes your Raider 365 Aluminum chassis and gives your pistol optic a dedicated home out front. Instead of relying on your slide-mounted dot, this bridge moves the optic forward for a cleaner sight picture and a more purpose-built setup on your P365-based PDW. It's machined from 7075-T6 aluminum, so it adds strength without piling on weight where you don't want it.

Where the Raider 365 Optic Mount Fits

This one is built specifically for the Raider 365 Aluminum chassis and the SIG P365 fire control unit that lives inside it. If you're running the Ultralight polymer chassis, this isn't the mount for you, so double-check which version you have before ordering. It's a fixed, non-reciprocating bridge that sits flush against the top of the aluminum frame, keeping the whole package tight and streamlined.

Optic Options and Build

The multi-cut footprint plays nice with a good range of micro red dots, covering the Trijicon RMR, Shield RMSc, and Holosun K-series patterns. That gives you room to run what you already own or pick the dot that suits your build. If you're mounting an RMSc-footprint optic, there are set screws included to block off the unused holes for a clean fit.

What to Know Before Install

Everything installs with T10 and T15 screws, and Flux recommends torquing them to 15 in-lbs with the included Vibratite thread locker to keep things locked in. Worth noting: tall sights like the P365 Fuse aren't compatible with the forward optic hood, and the mount has to come off before you can pull certain slides. It's a straightforward upgrade for anyone dialing in their Raider 365 for range time or training, and Flux backs it with US manufacturing right alongside the chassis itself.
