Questions & Answers
Will the pic rail section on the .875 seat block be on the same plane as a small frame ar upper receiver rail section? Expert Answer

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.

will this fit on a vr80 barrel Expert Answer

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