No, it will not be the same height as these are meant to match Armalite AR-10 .308 uppers which are significantly larger than a standard forged AR-15 upper. This means the height provided by this gas block would be taller than a standard AR-15 upper.

There is no guarantee on fitment as these are meant for Armalite .308 AR upper receivers and are meant for standard AR-10 barrels.

This is meant specifically for AR-10 Armalite upper receivers and barrels regardless of gas system length. This is not meant for an AR-15 upper receiver set up.
