The Wallbreaker 16-inch AR-15 5.56 NATO Rifle Upper Build Kit from Davidson Defense is engineered for durability and precision. Centered around a Match Grade "Fiddler" 16" barrel crafted from 416R stainless steel, it features a carbine gas system with a 1:8 twist rate, ensuring reliable and consistent performance. The kit includes a stripped upper receiver made from 7075-T6 aluminum, anodized for corrosion resistance, and designed with M4 feed ramps.

A KeyMod handguard constructed from 6061-T6 aluminum enables easy attachment of accessories while maintaining a lightweight profile. The assembly is completed with a Recoil Technologies micro low-profile gas block and an AR-15 birdcage flash hider, both contributing to the overall reliability of the rifle. This upper build kit is ideal for gunsmiths seeking high-quality components for their AR-15 configuration.
