The Radian Weapons Upper/Handguard Set (Radian part no. R0619) pairs a billet 7075-T6 upper receiver with a matching 15.5-inch M-LOK handguard, finished together in a Radian Cerakote brown for a seamless look. The upper ships with the dust cover, forward assist, and Radian Raptor-SD ambidextrous charging handle already installed, and the handguard attaches to the barrel nut with four black nitride-coated steel cross bolts and an anti-rotation pin for a rock-solid mount. Every edge is machined and chamfered so there are no sharp corners to catch a support hand during a fast grip change. This set does not include a lower receiver, barrel, or bolt carrier group, so plan on supplying those separately to complete the build.

• Includes a lightweight forward assist pre-installed.
• Comes with a Raptor-SD ambidextrous charging handle already fitted.
• Handguard attaches using four black nitride-coated steel cross bolts at the barrel nut.

Frequently Asked Questions

What is included in this set? You get the matched billet upper receiver and 15.5-inch M-LOK handguard with the dust cover, forward assist, and Raptor-SD charging handle already installed; no lower receiver, barrel, or bolt carrier group is included.

Do I need a lower receiver to use this? Yes, this set is a bare upper and handguard only, so you will need a compatible complete lower to finish the rifle.

Does a 15.5-inch upper make this a Short-Barreled Rifle? No. Putting it on a shouldered rifle lower makes a short-barreled rifle; since October 9, 2026, ATF no longer requires Form 1 approval or registration for that, but state law still applies, and taking an SBR across state lines needs an approved ATF Form 5320.20.
