aThe DD15-A4 20-inch Rifle-Gas 1:7 5.56 NATO AR-15 Upper is crafted for performance, reliability, and customization. At its core is a 20-inch 4150 CrMoV steel barrel with a 1:7 twist rate, ideal for stabilizing a variety of 5.56 NATO bullet weights. The rifle-length gas system and 0.750 gas block ensure smooth, consistent cycling, even during extended use. Built on a 7075 T6 aluminum upper receiver with a durable black anodized finish, this upper is paired with an aircraft-grade aluminum quad-rail handguard for maximum strength and accessory compatibility.
Included with this build are Magpul XT Rail Texture Panels, providing a more secure and comfortable grip on the rail system without adding unnecessary bulk. A 1/2×28 TPI standard GI Birdcage flash hider is pre-installed to help reduce visible muzzle flash. Whether you’re building a classic service-style rifle or a dependable long-range setup, this upper is ideal for builders seeking time-tested components and enhanced ergonomics.
