I have a MP5K PDW clone and a MP5N clone that I have put together over the years. I am really happy with them. Recently after a long talk with Jeff (Ghilliebear) I managed with his suggestions to change out the locking piece to a RCM 100 degree and swap the bolt head for a RCM, the PDW is running flawlessly. My MP5N has always been 100%. Now I am going to venture into new territory. Ive been wanting to put together a MP5SD clone for a long time. Today I bought this MP5SD clone receiver that is barreled and finished already. I have around $780.00 in it. With the help of Adam @ HKParts | Heckler & Koch Genuine Parts - HKPARTS.NET am hoping to finish this off rather quickly. As soon as the reciever arrives Ill get the Form 1 submited and start populating parts. The questions I have are about the silencer. I would like to fire it unsurpressed with regular ammo. That being said.......Who makes a fake can that will thread on so I can fire the gun? Also who makes a real can for a MP5SD? I figure Ill use a fake can and a 100 degree locking peice and it will run unsurpressed like a champ. Are there any details, words of advice, things I need to be aware of with the SD platform before I get started? I am hoping to keep this one under $2K with a fake can, and $200 dollar stamp. Thank you guys in advance for your help in this project. I keep you posted on the progress. Colt My goal is this: Wanna kill these ads? We can help!
