The SilencerCo Threaded Barrel for the Glock 43 (brand part number AC5049) is a 3.39-inch replacement barrel made from 416R stainless steel, finished in black with a right-hand 1/2×28 thread pattern. This version ships without the serialized piston, so shooters who already own a compatible piston can save on a barrel-only purchase, while anyone starting from scratch will need to add one separately to complete a suppressor host setup.
