Flux Defense Raider 365 Ultralight PDW Chassis & Holster

The Flux Defense Raider 365 Ultralight PDW Chassis turns a Sig P365 into a compact, high-capacity PDW without the weight of a traditional carbine platform. Built for IWB, OWB, or off-body carry, this chassis delivers up to 50 rounds on the gun in a package 3" shorter and 85% lighter than an MP5K.

Features:

• Compatible with P365XL, TACOPS, and P365 FUSE slides
• Works with 17, 21, and 25-round P365 magazines
• Spring-loaded brace/stock, collapsible for compact carry
• Patented Speedload System for fast reloads, up to 50 rounds on the gun
• Ample internal space for most common pistol suppressors
• Advanced polymer composite and S7 tool steel construction
• Type 3 hard coat anodized shroud
• Collapsed: 9.75" x 4" x 1.375" / Extended: 18.5" x 4" x 1.25"
• Weight: 8.7 oz, length of pull: 13.5"
• Includes removable shroud and adjustable 2.0 holster with hardware

The Ultralight builds around a spring-loaded brace/stock system that collapses for concealed carry and deploys instantly for a more stable, accurate firing position, all while adding minimal bulk to the pistol. A patented Speedload System allows for faster reloads than a comparable pistol, PDW, or rifle, and with 17-, 21-, or 25-round P365 magazines, the gun can carry up to 50 rounds when loaded and staged for immediate use. The chassis is built from advanced polymer composite and S7 tool steel, with a Type 3 hard coat anodized shroud protecting the internals, and there's enough internal clearance to run most common pistol suppressors up to 1.55" in diameter without interference.

The included holster is fully adjustable and can be worn inside or outside the waistband, or mounted off-body, giving shooters flexibility in how they carry the system day to day. An optional flared magwell speeds up magazine changes under pressure, and an optional 6" barrel adds velocity while keeping the overall length shorter than an MP5K. The Ultralight is built specifically for the P365XL, TACOPS, and P365 FUSE slides with 17-25 round magazines; it is not compatible with the standard 3.1" P365 slide, the Xmacro Comp/AXG Legion slide, 12-15 round magazines, or the original aluminum R365 holster and magwell.

Flux Defense designs its PDW chassis systems specifically around compact carry pistols, focusing on real reductions in size and weight rather than simply scaling down rifle components. The Raider 365 line reflects that focus, aiming to deliver rifle-like control and capacity from a package that still carries like a pistol.
