View Full Version : Started a MP5SD build Have questions......

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 (http://www.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.

So I sat down and figured up the cost. Here is what I have so far:
Here is what I have researched for the build $$$
1. MP5SD barreled upper from BMP $835.00
http://www.gunbroker.com/Auction/ViewItem.aspx?Item=257801686
2. Converted Semi SEF Lower from RTG $280.00
http://www.robertrtg.com/hk94semiautofcg.html
3. POF A3 collapsible stock from RTG $215.00
http://www.robertrtg.com/pofmp5collapsiblestock.html
4. US Made (RCM) and German MP5/94 Bolt group $480.00
http://www.hkparts.net/shop/pc/MP5-94-Bolt-Group-US-German-HK-90p2201.htm
5. MP5 Stock push pin $6.00
http://www.hkparts.net/shop/pc/HK-German-Butt-Stock-Push-Pin-5p76.htm
6. Fake silencer to seal holes in barrel $XXXX?
http://www.rdts.com/HKMP5SD.html
7. BATF Form 1 tax stamp $200.00

Total should be $2016.00 plus the Fake can. I have to call RDTS monday for a price quote. I included shipping and transfer fee in my calculations.
What were the Coharie Arms MP5SDs selling for? the way I figure it, I will have a better product by doing it my self, with the parts list Ive came up with. Any suggestions, thoughts?
Thanks

Nothing special here. I enjoy building guns. So I always get excited about new projects.
I found a real silencer for it for fairly cheap:

For a silencer any brand should fit as long as the threads match. Usually on sub guns people will have a short but fat can on the thing. One of my friends is a class 3 dealer and has his SOT and whatever else it takes to buy and sell cool stuff. He's really good friends with the guy that owns SAS suppressors, and that guy builds custom ones all the time for people. I hope somebody can give you better advice than me. I don't think I've ever seen a mp5 other than one of those gsg5's. You should call this guy named major malfunction (if you search his name, his website should come up). From what I hear, he knows his stuff!!

I wish it took a normal supressor. The SD version has holes at the rear of the barrel like a compensator. The supressor is designed to be internal or some what intergrated. Check out the pictures.

Well so far I ordered the
Upper $800.00 + $35.00 shipping/transfer
Semi Auto clipped and pinned lower $282.22 shipped
Complete BCG, return spring and stock push pin $479.89 shipped
A2 fixed stock $55.00

Still need
All thats left is the fake can from RDTS I estimate $200.00
and the Form 1 tax stamp $200.00
This brings the total to: $2052.11 for a MP5SD Clone extremely excited but $52.11 over set budget.:faint:

Well Colt I believe in credit where credit is due , those are some awesome automatic weapons!! In NJ we basically have the worst laws in the union, and also basically copied the AWB. So we can't do no NFA stuff here, no autos no SBR no suppressors.

Which is ashame because I really would save up for a top top top of the line AR for SBR and Suppressing.



On another note - not that ou asked , but I have some MP5 experience...about $250 worth at The Gun Store on my first trip to Vegas and ALOT of time money and mags worth of ammo on my second trip lol ... I really really like the look feel and use of the 'full' stock on the Mp5 , and can't do that sliding small stock. You like it. ?

For Me it would be the actual stock or an MP5PK on a sling like a MS2 for hanging in front of me. But I'm curious since you e got so many of these WhAt your thoughts are thx sir

Im with you I perfer the A2 fixed stock. I am putting one on this SD project. I have a collapsing MP5F stock on one and my MP5K PDW has the correct folder. They work but are a bit akward at first.
This is what I will be shooting for with this build:

B&T makes the top of the line stuff, probably the best on the market. But this was made by HK contracted under Choate.

I don't know if you're a member of silencertalk.com but sas suppressors get pretty good reviews. I'm getting the guy to make me a few different cans and it's really hard to get ahold of the guy. My friend shoots with him sometimes and knows him. I forgot his name, but he's a cool guy that knows what he's talking about. It seems like you could thread the end of the barrel and just make the can come all the way down and cover that up some how. I could be wayyy wrong because I've never seen a barrel like that but I'm sure that I can get you some info. Now I'm curious, and want to know for my own personal knowledge. So I'll try and find something out for you!!!

Let him know it will be a SBR so length does not matter. Our goal is to close off those holes. I want to fire it unsuppressed. I can get thread pitch info ect. Thanks Colt

11-06-2011, 20:08
No doubt. Yeah I figured it was a small barrel 5.5 inch or so. That was just a guess, so if I'm wrong it's because I haven't clicked on the link that you posted at the top on how much the barrel and everything else cost. Tomorrow I'll be on it like stink on dung, to get some info for you.

Nice build! What sort of quality are the Black Hole Arms if I might ask? If I am able to, I will be doing an MP5k clone in the next 6 months. I am trying to determine if the best route is to start off of a pistol, or go the route you did with a receiver and parts.

11-07-2011, 05:03
i think someone posted a coharie sd clone up for 1600.00 on gunbroker. that is a two stamp gun, one for the sbr and one for the suppressor so 2k total.

Wow... good luck finding an MP5SD suppressor!

I wasn't sure if the Ol' SD would outperform a Standard or K-gun and more modern suppressor, but apparently the results show that they are as good or better. It is heavier though, but shorter too... and effective at reducing the velocity of standard NATO ammunition (115/124).

Two interesting threads for you:

RDTS makes them $700.00 plus stamp
RCM makes them $600.00 plus stamp
KAC makes them $1600 plus stamp
Coharie Arms makes them $400.00 plus stamp
Ill proubably go with RDTS they have a great reputation and the price is nice too.

Alright man, I was going to send you a PM but I figured I'd just say it on here. This is what I was told. To get a custom one, it'd cost more than to buy one of the three that you listed above and it would probably take longer to get. I also was told this and I'm not sure if this is true because I haven't looked it up but it sounded believable so I'll say it on here. My buddy told me that they made the mp5sd the way it is because whatever army used or uses them can only get supersonic ammo and those holes in the barrel will slow down bullets to subsonic speeds. Then he went off on a big tangent about how cool those guns are. Man sorry I couldn't help you out anymore. He said he didn't know which one is the best because he's never heard any in person.

IMO, I don't think you could go wrong with any of them to be honest. The way he said the barrel is designed, they all should be pretty quite.

Matt,
Thank you for looking into it for me. Your buddy is correct, I see he knows a thing or two about the MP5SD platform. The gas bleed holes in the barrel allow the gases to exit into the surpressor as the bullet begins to enter the barrel. That causes regular ammo to become sub-sonic. Thus this is the quietest sub-machine gun avalibel. This is a exciting build. I got Ralph Smith at RDTS to make me a fake can that will seal off the gas ports so I can shoot it unsurpressed, for now. He is making it to specs of the real SD cans he offers. $210 shipped not bad for a custom made gun part. :supergrin:

Yeah man anytime!! I wanted to find some stuff out about it to because I've never seen one of those or a barrel like that. That thing is going to be super cool once you get it complete!! It's already bad ass, but you're taking it to the next level!!!

I'd also say that's a deal on a custom piece too!!!

Most of the parts have came in. Still waiting on the receiver and fake can. I filled out the Form 1 paperwork. Just need the S/N and then drop at Chief of police's office for signture. Then wait with the end cap on. I dont mind though. At least I can shoot it that way while I wait. Gives me a chance to work out any bugs.

Well today I got the receiver in. I lubed and assembled the parts. It is pretty impresive. I am still waiting on the fake can so I can shoot it. It manually cycles smoothly. Everything fit together perfectly like a glove. I think I am going to order a Supressor this weekend and start the SBR form 1. Then wait.................... I also swapped the lower with my fullsize Navy. I like it its shaping up:)

I found dealer here local First Choice Pawn that will accept and transfer the surpressor for me. He wants a $100.00 for the paperwork and transfer. Is that a normal price? I will have $700 in the can $200 in stamp and $100 in transfer.

When the fake can arrives Ill make a video and fire it for you guys.

Good news. I got a call today from Ralph at RDTS. The fake can will be in route in the next couple days. He said it is done. An props for the quick response to my message left on Sat. He seems like real good people! Heading out of town for the holidays. When I return I will get a video up of the test fire:) Then finish the long wait on the RCM silencer I ordered and Form 1 approval:(

Well fellas,
How about a update. I finally reiceved the fake can from RDTS. Crazy wait involved but a outstanding product none the less. I installed a 100 lock pcs and the oring and fake can. Now I will hopfully get some trigger time this weekend. I will video. The Form 1 is in the mail. Long wait now:( RCM is supose to be starting the silencer builds for us this month. So thats another long wait after its done 3-6 months for that ATF aproval. Eventually Ill have this done. In the meantime Ill enjoy my SD pistol that is not silent:)

Alright fellas,
If you have been following this build, We test fired it today with a RCM 100 lock peice installed and the RDTS fake can. We put 300 rounds through it of Winchester White box Walmart ammo.
The very first round as seen in the video failed to eject. After that, 299 perfect rounds fired. Totally impressed. RCM, Adam Webber I thank you for the outstanding product. Even the SW reciever I bought from BMP is spot on 100%. Its a exciting time in the HK Platform world, when quality parts are so plentiful to us guys that love them. I am waiting on the form one to come back so I can install the stock. Also RCM started the silencers this month last I was told I should verify that.
