Spike's Tactical Pipe Hitters Union (PHU) combat rifle is the result of a collaboration with Pipe Hitters Union attitude apparel and has been built to the specifications of the Pipe Hitters Union CEO. The chrome moly vanadium, cold hammer forged barrel is chrome lined with 1/2x28 threads and mil-spec phosphate coated. Its upper receiver is constructed of 7075-T6 with a free-floating 13.2" M-Lok rail and Spike's Gen 2 billet sights, while the lower has a low shelf, RDIAS compatibility, Pipe Hitter Skull logo, and Q.D. attachment points. The mid-length gas tube has a black nitride finish inside and out. The MFT Battlelink Minimalist stock features a 6-position mil-spec buffer tube and MFT grip. The Crusader also features a two-stage CMG trigger, ambidextrous safety and includes a hard case and Hexmag.
