The Rock River Arms (RRA) AR-15 RRAGE Upper (including the standard RRAGE Upper, the RRAGE 2G Upper, and the RRAGE 3G Upper) is designed to provide a balance of performance and affordability. Made from extruded 6061T aluminum, the upper receiver features clean lines and sharp angles, resembling more expensive billet designs while maintaining strength and precision. It includes a 16" chrome moly barrel chambered in 5.56 NATO, allowing the use of both 5.56mm and .223 ammunition, with a 1:9 twist rate for versatility across bullet weights. The RRAGE Upper also incorporates a free-float M-LOK aluminum handguard that aligns seamlessly with the upper, creating a monolithic appearance. A carbine-length gas system, low-profile gas block, and a standard A2 flash hider complete the setup, contributing to reliable cycling and reduced recoil. This upper has been well-received for its lightweight construction and streamlined design, making it an attractive option for budget-conscious AR-15 enthusiasts. Weighing approximately 5.7 lbs when assembled into a carbine, it offers easy handling and compatibility with various accessories. While it lacks features like a forward assist and case deflector, these omissions are seen as reasonable trade-offs for its affordability and intended recreational use. Variants such as the RRAGE 3G Upper, with a 15" rail and mid-length gas system, cater to competition shooters. Overall, the RRAGE Upper is a reliable and aesthetically pleasing choice for shooters seeking quality without breaking the bank.
