  • Uses standard front sight windage drum and pin
  • Has built in cleaning rod holder
  • Cast in the US using Wax Casting techniques similar to the modern Russian barrel components
  • Machined in the US

GBC-13 is a copy of the East German 74nk Front Sight Gas Block Combo

It all started with a high definition scan of an original part from Larry Vickers, then we teamed up with Sabrewerks13 to oversee the casting process, and finally back to JMac Customs for machining.
