Had to return first one, but replacement is excellent - Faxon Firearms .223 Wylde Gunner Profile AR-15 Rifle Barrel

16" model. First one had a bad chamber (off-center), but was very easy to return to Optics Planet, who replaced it with no questions. Replacement unit is excellent, POI does not move when heats up, which is good. Overall it performs very well. Borescoping it shows a very polished bore and just good overall construction. After mounting it and zero'ing this is a 1 MOA barrel with good ammo. For a lightweight feature rich item, this is an outstanding BBL. For the price, is total deal. I would buy another in a heartbeat.
