The Troy Industries A3 pistol in .223 Remington (brand part no. SPST-CA3-10BT-B1) is a lightweight, ultra-low-profile AR pistol built around a 10.5-inch barrel and Troy’s BattleRail forend. Troy Industries caps the barrel with an A2 flash hider and cuts the rifling at a 1-in-7 twist, and the aluminum receivers keep overall weight down for one-handed maneuverability. A standard safety selector and a flat trigger guard round out the controls, and the LFT handstop on the BattleRail gives a consistent reference point for the support hand. Among AR pistols built for lightweight handling, this A3 configuration favors shooters who want a low-profile, optic-ready platform.
