Details

The Davidson Defense LAZR 18-inch Rifle Gas 5.56 NATO AR-15 Upper Build Kit is engineered for performance and reliability. This kit features an 18-inch Government Profile barrel made from 4140 Gun Steel, finished with nitride for enhanced durability. With a 1:7 twist rate and a muzzle thread pitch of 1/2x28, it achieves optimal accuracy and stability with a variety of 5.56 NATO ammunition. The upper receiver is crafted from 7075 T6 aluminum, featuring M4 feed ramps and an anodized finish for lightweight strength.


A micro low-profile gas block ensures smooth operation in a rifle-length gas system. The included Plan B Scorch 3-Prong Flash Hider effectively minimizes muzzle flash, making it an essential component for low-light shooting conditions. Complemented by a quad-rail handguard constructed from aircraft-grade aluminum in black, this upper build kit is built for the freedom of customization and performance on the AR-15 platform.
