Joseph - There are lo profile gas blocks available to fit virtually any AR-15 barrel in commercial production. The most common diameter gas block is .750" (Inside diameter) and the most common AR-15 barrel uses a .750" size gas block. There are other sized barrels (.875", for example) and they take a .875" gas block. Low Profile only refers to the outside diameter/height of the gas block, and literally means nothing at all about what barrel it will fit. Lo-Profile gas blocks come in various sizes, to fit the variously sized commercially available barrels. Just remember gas block 'size' is the inside diameter - gas block 'profile' deals with the outside measurements. I'm confident Troy makes a lo-pro gas block to fit this barrel.
