This depends on the gas journal diameter of your barrel. Most 5.56/.223 AR15 model rifles will use a 0.750" gas block but it can vary depending on barrel profile and caliber. Please email us at Techsales@opticsplanet.com and let us know the specific make and model of your AR15. That way we can accurately recommend the correct size gas block.
