Rock River Arms manufactures quality AR firearms and components to meet the needs of everyday shooters. Their RRAGE 3G upper is chambered for 5.56 NATO and comes completely assembled with a bolt carrier group and charging handle. It features an extruded aluminum A4 receiver with a sleek no forward assist design, 16" chrome moly barrel, and free float handguard. The muzzle has an A2 flash hider installed on 1/2x28 threads and can easily be upgraded depending on your needs. Rock River chose a carbine length gas system with a low-profile gas block tucked under their 15" RRAGE 3G rail for a clean tactical look. The handguard design also includes two short picatinny top rails for optics mounting, angled vent holes, and enough M-LOK slots to attach your favorite accessories. As a complete upper, all you need to supply is a finished lower and sights to have a full firearm ready to hit the range. If you have an outdated rifle that needs an upgrade or planning a future custom build, Rock River's RRAGE 3G upper is an excellent balance of performance and aesthetics at a price that won't break the bank.
