The Aegis Lightweight 18-inch Rifle Complete Upper Build combines performance and versatility in a robust AR-15 platform. Chambered for 5.56 NATO, the 18-inch government profile barrel features a 1:7 twist rate, maximizing stability for various bullet weights. Constructed from 4140 gun steel and finished with a nitride treatment, this barrel ensures durability and longevity. The rifle-length gas system utilizes a low-profile gas block for smooth operation.
The 7075 T6 aluminum upper receiver is anodized for corrosion resistance, while the 6061-T6 aluminum M-Lok handguard offers lightweight and modular accessory attachment options. Completing the setup, the Plan B Scorch 3-Prong Flash Hider effectively minimizes muzzle flash, providing tactical advantage. This complete upper build is ideal for gunsmiths seeking freedom in customization and reliable performance in the field.
