Faxon firearms .224 valkyrie heavy fluted profile barrel - Faxon Firearms .224 Valkyrie Heavy Fluted AR-15 Profile Barrel

The barrel is well-made, however there are a couple of mechanical issues with it. First, the gas hole is tiny and difficult to align since there are no dimples in the bottom side of the barrel. Second, the gas hole lines up with the flutes, not the upper receiver. When the barrel is seated to the upper receiver, the top flute and gas hole should be aligned with the top and it's not. This means that when the gas block is located accurately, it is slightly off-center of the top of the upper receiver. I don't believe this misalignment is enough to affect the operation of the gas tube inside the upper receiver, but I have yet to try the rifle.
