The One Horse Express From GunCon 2026 #guncon
The One Horse Express, a new AR-15 upper receiver assembly from One Horse, was launched at GunCon 2026. It features a 16-inch enhanced SOCOM barrel with a beefed-up profile to mitigate muzzle rise, a mid-length gas system, and a robust handguard design that indexes off both the barrel nut and upper receiver for stability. The assembly includes an M16 profile MPI-tested bolt carrier group, a Schmid single-stage mil-spec trigger, an ambidextrous charging handle with gas ramps, an H2 buffer system, and a Thrill grip. A key feature is the Atrius Development Group selector, offering safe, semi, and accelerated modes. Tested with 5,000 rounds of Winchester White Box and 62-grain green tip ammunition without a single malfunction, the One Horse Express is positioned as a reliable and affordable option with an MSRP of $999.
