Remove the following parts:

  • Trigger group

*** You MUST ship the upper signature required to be sure we receive the gun.



We have done over 500 conversions just for the MP5SD alone. We can make them full auto-ready for those with registered sears or packs.  We are required to weld a typical Shelf on the receiver like the Pre-ban HK’s (hk94, Sp89)  if we remove the bolt block. This process is an additional $175 to weld the bolt and remove the auto bolt block. We are currently 8 weeks for the full conversion. Upon payment, we will transfer the suppressor immediately and then send the gun when complete, the gun CAN NOT be fired without the suppressor or a fake suppressor due to the ports in the barrel.
