I am selling my custom made Shark 15-SD 9mm Suppressor that I had built for my AR15 9mm SD-type upper. It has a 3-lug adapter that will work on a AR-15 9mm 3-lug barrel or on an HK MP5 3-lug barrel.
The overall length of the suppressor is 14 inches (adapter is 1.5 inches). It has been used only once to test functionality and it is in perfect condition. It is super quiet (as is all of David's suppressors.) I sold my M-16 with the 9mm SD upper ac few years ago and this has been sitting in the safe.
Price is $700 and you will be responsible for the tax stamp(s). I would prefer to sell locally in DFW, TX (I am in NW Plano near 121 and the Tollway). Full payment required to start the paperwork. If you are outside of DFW, I can ship it overnight to you. Shipping will be actual cost plus insurance.
If you have questions, shoot me an email or PM.
