Radian Weapons Model 1 AR-15 300 Blackout 9" Complete Upper - Black Nitride

The Radian Weapons Model 1 Complete Upper is a complete upper-receiver assembly for an AR-15-pattern lower, chambered in 300 Blackout. Its compact configuration is suited to AR pistol builds or properly registered short-barreled-rifle configurations.

This upper uses a direct-impingement, pistol-length gas system with a low-profile gas block. The 9 in match-grade 416R stainless-steel barrel has a black-nitride finish, polished crown and feed ramps, a 1:5 twist, and 5/8x24 muzzle threads.

The upper receiver is machined from 7075-T6 billet aluminum and finished in Radian Black Cerakote. It features M4 feed ramps, a port cover, and a lightweight forward assist. The proprietary 8 in aluminum handguard provides Magpul M-LOK mounting slots, a full-length top Picatinny rail, and an integrated stainless-steel upper-to-handguard anti-rotation pin. No sights are included, leaving the upper optics-ready.

Included are a Radian Enhanced M16 bolt-carrier group with a black-nitride finish and a Radian Raptor-SD suppressor-optimized ambidextrous charging handle. A lower receiver, magazine, and lower fire-control components are not included. This item is offered in New Condition.
