Radical Firearms manufactures high-quality replacement and upgrade parts for the AR platform that won't break the bank. This complete upper assembly would be an excellent choice for a new tactical build or to modernize an outdated AR-15. Radical assembled this forged M4 upper with a 16" Socom barrel chambered for 5.56 NATO. It does come threaded 1/2x28 with a tried-and-true A2 flash hider already installed. While the 1:7 twist rate performs exceptional with heavier bullets, medium weight projectiles should be satisfactory for most recreational shooting applications. Radical also selected a nice 15" RPR free float M-LOK rail to maximize accessory mounting options. These longer handguards do a great job to hide the barrel for achieving peak tactical aesthetics. Whether you're looking to build a rifle from scratch or upgrade an older carbine, Radical's 16" 5.56 complete upper would make a great addition to your arsenal.
