All barrels are individually checked for headspace by precision custom hardened gauges.
General Barrel Info: The Barrel on an AR-15 pistol operates through a 'gas impingement' system, where gas is tapped from off from the barrel and cycle back through a connected gas system, to help the bolt carrier in unlocking and extracting a spent cartridge.

Thanks to the modularity of the AR-15 platform, your next pistol will be incredibly easy.
