The Orome 18-inch AR-15 6MM ARC rifle complete upper build from Davidson Defense is engineered for precision and lightweight performance. Chambered in 6mm ARC, the upper features an 18-inch medium-profile barrel made of 4150 CrMoV steel with a nitride finish, providing durability and accuracy with a 1:7.5 twist rate. The mid-length gas system uses a micro low-profile gas block, ensuring reliable cycling and reduced recoil. Constructed from 7075 T6 aluminum, the stripped upper receiver is anodized for enhanced corrosion resistance and includes M4 feed ramps. The handguard, made from 6061-T6 aluminum, features an M-Lok design in sleek black, allowing for modular accessory attachment. The upper is completed with a Mil-Spec charging handle and a GI Birdcage flash hider threaded at 5/8x24, which minimizes flash signature. This complete upper is a solid choice for gunsmiths and shooting enthusiasts who prioritize versatility and reliable performance.
