This AR-15 upper assembly features the Radical Firearms generation 3 15” FHR Hybrid Rail System that has a new mounting system that ensures the handguard stays tight against the barrel nut and receiver. It is a free-float design, meaning it does not contact the barrel which could result in inconsistent accuracy like standard M4 delta ring handguards. It has Keymod slots along the sides and bottom with built-in picatinny rails at the muzzle end for mounting any tactical accessories that you want. The full length picatinny top rail offers a solid mounting point for scopes, red dots, or iron sights to increase the effectiveness of your rifle.

With a huge selection of AR-15 parts and accessories to choose from, it can be difficult to decide which parts to purchase for your next build. Radical Firearms has you covered with this barreled upper receiver that contains all the upgrades you could want in a semi-automatic 5.56mm rifle. This assembly features a 16” 4140 chromoly barrel with a melonite coating for long-lasting durability and exceptional corrosion resistance. The SOCOM barrel profile is designed to increase accuracy potential by providing a thicker, more rigid barrel that is less likely to move during prolonged firing. It has a 1:7 rifling twist rate that can stabilize a wide range of bullet weights and M4 feed ramps in the barrel extension to ensure reliable feeding with all types of ammo. Attached to the 1/2x28 muzzle threads is the Radical Firearms Zero Impulse muzzle brake that vents excess gas pressure upward to reduce muzzle climb and felt recoil so you can get back on target faster. This affordable upper receiver comes completely assembled, all you need is a bolt carrier group and charging handle and attach it to a complete lower to have a functioning rifle for a fun day at the range.
