Founded in 2010, TacFire has rapidly grown to become one of the most recognizable suppliers of budget minded AR parts on the market. This AR-15 upper is chambered for .300 AAC Blackout and comes fully assembled with a bolt carrier group and charging handle. Its 16" barrel has a nitride finish, 1:8 twist rate, M4 feed ramps, and threaded muzzle. While it comes with an A2 flash hider, the 5/8x24 threads are a common pitch which allow for unlimited upgrade possibilities. One of the unique aspects of .300 is the gas system length. Unlike 5.56, this upper is designed with a pistol length gas system to ensure optimal cycling and performance. TacFire has also tucked a low profile .750 gas block neatly under the 15" free float M-LOK rail. The top side of the handguard features two short picatinny rail sections perfect for mounting sights and there are plenty of M-LOK slots at the 3/6/9/12 o'clock positions to install your favorite light, laser, forward grip, bipod, or other compatible accessories. Whether you are planning to assemble a rifle from scratch or upgrade one that is out of date, TacFire's .300 Blackout upper would make an excellent addition to any build.
