Overview

The Spike's Tactical Bi-Axial is a compact semi-automatic AR pistol chambered in .223 Remington / 5.56x45mm NATO, built around an 11.5-inch cold hammer forged barrel. A standout feature of this model is the Aviator Arms X-1 internal spring recoil system housed within the upper receiver, which eliminates the traditional buffer tube setup to deliver a short, soft-shooting platform. The recoil system includes a detachable sliding visual indicator secured by three screws that allows the operator to track bolt carrier group travel. The firearm is constructed with 7075-T6 aluminum components and features a 9-inch M-LOK handguard, an A2 flash hider, a Spike's Tactical battle trigger, an Ergo grip, and KNS anti-rotation pins. The lower receiver is finished with an M4 quick-detach staked castle nut and latch plate.
