The Ballistic Advantage Premium .223 Wylde Barrel uses a 0.750" gas journal. I would recommend using the Ballistic Advantage Lo Pro Gas Block, linked below. However, any 0.750" gas block would fit including adjustable gas blocks. The 16" barrels will work with any mid-length gas tube. The 18" barrel will work with any rifle-length gas tube.
