coolrider Posted June 19, 2023 Report Share Posted June 19, 2023 (edited) For sale is my HK MP5SD SBR sear host built from an HK94 by RDTS I do not have the Suppressor. I bought this with my sear and since the sear and the SBR were on form3's and the suppressor was on an out of state form 4 I decided to let them keep the suppressor and I ordered a new TPM suppressor not knowing that the thread on the barrel was different until the suppressor arrived, and it didn't fit. Since then, the SD has just been sitting. This has the old-style threaded barrel RDTS used to use. When I spoke with Ralph Senior at RDTS he said he can still make a suppressor with this old-style thread. The finish is very nice, and the gun is very clean overall. It has a New PTR semi trigger pack since that's what I had laying around. Currently on a Form 4 in Florida if you are local and want to meet up to see it let me know there is a really nice store/ range near me. $10,500 Edited September 6, 2023 by coolrider Link to comment Share on other sites More sharing options...

Gaffshot Posted September 18, 2023 Report Share Posted September 18, 2023 What is the thread pitch? Link to comment Share on other sites More sharing options...
coolrider Posted September 18, 2023 Author Report Share Posted September 18, 2023 It is the one RDTS used to use I think 12x something? He can still make cans for that thread pitch, or he can change the barrel. Link to comment Share on other sites More sharing options...

WTFOver Posted September 19, 2023 Report Share Posted September 19, 2023 (edited) Hi Our MP5SD HE's produced in the last 5 years or so are exact HK thread pattern 18mm. Our barrels are machined to HK MP5 SD spec and utilize our proprietary porting which nets approx. 1065 fps as opposed to HK factory porting of 930fps. Any HK spec Suppressor will go on our MP5SD HE's. They will not however achieve the same suppression level available when our MP5SD HE Suppressor is paired with it. I can re barrel to the HK spec barrel and re-core our older Suppressors if you'd like. This MP5SD was built 11/2008 on an HK94 SBR that had been F1'd by customer.
