Davidson Defense Warden 11.5-inch Carbine-Gas 1:8 .223 Wylde AR-15 Freefloat Keymod Handguard Pistol Complete Upper Build

Warden 11.5-Inch Carbine-Gas .223 Wylde AR-15 Complete Upper

This is a complete upper assembly built around an 11.5-inch .223 Wylde barrel with carbine-length gas system. The KAK Industry barrel uses nitride 4140 CrMoV construction for durability, and the 1:8 twist rate stabilizes a wide range of .223 and 5.56 ammunition weights. You get a freefloat KeyMod handguard, micro low-profile gas block, and all the components needed to pair with your lower receiver.

• 7075-T6 aluminum upper receiver with M4 feed ramps
• Complete bolt carrier group and M4 charging handle included
• A2 birdcage flash hider with 1/2x28 threads

Freefloat Handguard Design

The 10-inch KeyMod handguard is freefloating, meaning it doesn't contact the barrel. This design eliminates barrel harmonics interference and improves accuracy consistency. KeyMod slots along the handguard let you attach lights, grips, and other accessories without adding unnecessary weight.

Barrel and Gas System Balance

The 11.5-inch barrel paired with carbine-length gas system creates a compact package that cycles reliably without over-gassing. The 1:8 twist rate is versatile enough to stabilize lighter 55-grain rounds and heavier projectiles up to 77 grains, giving you flexibility in ammunition selection without sacrificing performance.

Nitride Finish and Durability

The nitride-finished barrel resists corrosion and wear better than standard parkerized finishes. This barrel treatment is common in quality AR-15 builds because it handles both dry fire and extended shooting sessions without degrading. The micro low-profile gas block keeps the upper compact while maintaining proper cycling.
