Radian Upper/Handguard Set 15.5" Brn

The Radian Upper/Handguard Set 15.5" in Brown is a matched-pair upper receiver and rail system built for shooters who demand precision and durability in their AR platform rifle. This billet aluminum upper comes complete with a free-floating handguard, ambidextrous charging handle, and all the hardware needed for a straightforward install—no shopping around for compatibility headaches or missing parts.

Every component is CNC machined from 7075-T6 aluminum and finished in matching Cerakote brown. Radian reinforces the structural weak points that bog down lesser uppers: the receiver features a lightweight forward assist, integrated dust cover, and an anti-rotation pin to keep your rail locked in place under recoil. The four steel cross bolts securing the handguard are black nitride-coated to resist corrosion, and Radian chamfers every edge to eliminate the sharp corners that catch your hand during cleaning or rail-mounted accessory install.

The 15.5" handguard uses Magpul M-LOK slots for modular mounting, so you can attach lights, lasers, grips, and other gear without proprietary adapters. The included Raptor-SD charging handle is built for both right and left-handed shooters, letting you operate the bolt from either side of the receiver. Whether you're running this upper on a precision rifle, a duty-ready gun, or a field rig, Radian's attention to detail—machining, finish quality, and functional design—shows in every shot.

This is a complete upper assembly ready to marry to your lower receiver. The package includes the barrel nut wrench and all fasteners; you'll need only a properly headspaced barrel to complete the build.
