Aero Precision does not state the set screw spacing on the Aero Precision Adjustable Low Profile Gas Block. I recommend contacting Aero Precision in regards to that information.
This will be dependent on the size of the gas block journal for this barrel
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.
