Level up your SBR/AR pistol or registered lower with the Radian Weapons Complete Upper (R0452)—a premium, ready-to-run package built for reliability, modularity, and refined shooting manners in a compact format. Chambered in 223 Wylde for optimal accuracy with both .223 Remington and 5.56 NATO, this upper pairs a 10.5" precision barrel and carbine-length gas with Radian’s Enhanced BCG and Raptor-SD charging handle to tame gas and keep the action smooth—especially beneficial for high-round-count training or suppressed use. A lightweight 10" free-float M-LOK® handguard maximizes accessory placement and sight radius, while the Dead Air KeyMo Flash Hider gives you immediate KeyMo compatibility and excellent flash reduction. Finished in a durable FDE Cerakote, it’s as tough as it looks—and it looks exceptional.

Why Builders Choose This Radian Upper

• 223 Wylde Precision: Supports .223 Rem and 5.56 NATO with a match-friendly throat for improved accuracy potential and reliable feeding.

• Compact 10.5" Performance: Balanced dwell time on a carbine-length gas system for dependable cycling across a wide range of ammo.

• Raptor-SD Charging Handle: Redirects excess gas away from the shooter and gloves—especially helpful on short barrels and suppressed setups.

• Enhanced BCG Reliability: Radian’s Enhanced Bolt Carrier Group is engineered for smooth tracking and durability under sustained fire.

• KeyMo-Ready Muzzle: The Dead Air KeyMo Flash Hider offers excellent flash mitigation and quick-attach compatibility with Dead Air KeyMo suppressors/adapters (where legal).

• Accessory Freedom: 10" free-float M-LOK® handguard keeps your barrel isolated for consistent POI and gives ample rail space for lights, grips, QD cups, and IR devices.

• FDE Cerakote: Hard-use coating resists abrasion, solvents, and weather; pairs cleanly with FDE or black lowers and accessories.

Build Highlights

• Barrel: 10.5" 223 Wylde, 1:8 twist to stabilize a wide span of projectile weights (typically ~55–77 gr)

• Gas System: Carbine length, tuned for dependable function in a short package

• Handguard: Slim free-float M-LOK® (approx. 10") with anti-rotation interface and full-length top rail for optics/BUIS

• Muzzle Device: Dead Air KeyMo Flash Hider (threaded; suppressor interface)

• Charging Handle: Radian Raptor-SD ambidextrous, ported for gas mitigation

• Bolt Carrier Group: Radian Enhanced BCG for smooth operation and longevity

• Finish: Flat Dark Earth Cerakote on receivers/handguard for corrosion resistance and low-glare durability

• Fitment: Standard AR-15 lowers (NFA rules may apply for overall barrel/stock configurations)

Compliance Note: If assembling into a rifle with a barrel under 16", ensure you comply with all federal, state, and local laws (e.g., SBR registration where required).

Ideal Use Cases

• Suppressed setups: Raptor-SD + carbine gas + KeyMo flash hider make an excellent foundation for KeyMo-compatible cans.

• CQB/defensive training: Short overall length, fast handling, and robust BCG performance.

• Patrol & duty builds: Accessory-rich M-LOK® handguard and reliable gas system for professional configurations.

• General range use: 223 Wylde chambering extracts accuracy from both .223 and 5.56 loads, keeping costs flexible.

Setup Tips

1. Torque & align: When adding suppressor devices or rail-mounted sights, follow manufacturer torque specs and verify alignment.

2. Buffer tuning: Pair with an appropriate buffer/spring for your lower; consider an H/H2 and quality spring for short-gas balance.

3. Zero strategy: A 50/200-yard zero works well for 10.5" carbines; confirm holds with your chosen ammunition.

4. Sling & light: Add a two-point QD sling and 12/3/9 o’clock light mount to leverage the long top rail & M-LOK® slots.
