We have done over 500 conversions just for the MP5SD alone. We can make them full auto-ready for those with a 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.
