Have a POF MP5 with the threaded navy barrel w/ 3 lug.  



3 lug does not seem too secure without a TP, and does not fit with the supplied knurled TP that came with the gun.



Can is a Gemtech Multimount w/ their 3 lug adapter.





So, I guess I need a smooth thread protector to run it 3 lug, which I'd prefer doing, as opposed to my current fixed thread adapter.  



I've not ever seen one, but I've heard chatter that they exist.  



Can anyone tell me where to get one, or what the outer diameter specs are in case I need to have one made?

I think this might be what you're looking for: http://www.hkparts.net/shop/pc/HK-1-2-X-32-MP5-MP5K-Thread-Protector-German-9mm-152p108.htm

ETA: Check on HKPro to be sure. I don't know what the outside diameter needs to be, as I use the thread protector that came on my MKE.

See, I saw that...and it looked good until I looked at the pic, which shows a knurled TP  



They could have used a stock picture, who knows.

You are looking for a knurled thread protector that is turned on a lathe so it can be used with a 3 lug suppressor. Like the one linked by GeneralPurpose. Or you could have yours turned down to fit.

POF thread is 1/2 x 28 and the one on hk parts is 1/2 x 32, so it won't fit, I think it is just for German HK mp5's



I own one as well and have been looking but haven't found anything yet.

Do you know what its typically turned down to?





The one posted has an OD of .590

I measured my thread protector and its .580

I measured the ID of the mount and its .575



Without being smart on clearances and such, I'd assume my TP has to be smaller than .575, but...I'm not sure how much.

Gem tech makes one, unfortunately they have no idea when they'll being getting more.  They referred me to a different manufacturer, but that company said they're not making any until Feb.

TROS makes a thread protector that works on POFs.

Forgot about that guy



Even if he didn't, I'm sure he could.  I didn't see anything on his site but I've got an email out to him.



Thanks

You have to email him for items not listed on his site, like MP5 three-lug thread protectors He was having health problems earlier this autumn and his orders were significantly backed up but I believe he has caught up by now.

I asked him already, (He's the one Gemtech recommended) and he said he's busy making adapters and won't get to them until the end of Jan.
