Overview
Archie is the 11.5-inch short-barreled rifle in the One Horse Express Retros, a Vietnam-era CAR-15-pattern 5.56 carbine with the Atrius Mil-Spec Forced Reset Selector installed at the factory. One Horse named it in tribute to the A-Gunner who served alongside Carl J. Vondielingen, a U.S. Army Vietnam veteran from the Brownstown, Indiana area.
The barrel is an 11.5-inch 4150 CrMoV barrel with chrome lining, a QPQ finish, and a 1:7 twist on a carbine-length gas system. The forged 7075-T6 fixed-carry-handle upper has an A1 rear sight, an A2 forward assist, and no shell deflector. A carbine-length round clamshell handguard and a B5 CAR15 stock set it apart from the 20-inch Sarge.
Archie ships as a stocked SBR, not a brace pistol. It shares the Retros base package: forged 7075-T6 OH-15 lower, B5 CAR15 LS2 grip, non-F-marked front sight base, Mil-Spec A2 flash hider, Mil-Spec charging handle, and an M16-cut bolt carrier group with an 8620 carrier and MPI-tested 9310 bolt. A limited Tiger Stripe Camo Cerakote finish is offered alongside black.
