If your MPX does not cycle low velocity rounds, we can help out! This service includes removing the gas block, drilling out the gas port (barrel and block), and reassembly. We only need your barrel sent in. We open the barrel to .0625″ port size. Turnaround is 2-3 days.
Ship all barrels to our address:
