This gas block will fit any AR barrel that uses a .750 diameter gas block. This barrel uses set screws which would highly benefit from dimpling the barrel. Dimpling the barrel is the process of drilling small dimples into the barrel where the set screws can "lock" into place and secure the gas block. The dimples do not need to be deep and only the very tip of the set screws needs to be fit into the dimple. There are a ton of videos of people doing it online themselves, although we recommend you have an experienced gunsmith/armorer do the dimpling.
