Posted 21 Aug 2019 (edited) This is the OSS MR762SD (dual module/over the barrel supressor) made and designed for the MR for the CSASS trials. Obviously this was a short lived design but showed the engineering concept behind OSS and a totally new supressor design. I sold my MR and this just sits lonely in the safe, I never fired it on my MR. Due to the NFA process it will be a Florida sale otherwise it would be a 2 stamp transaction. I will pay the stamp for you and submit the form 4 after you supply your 2 sets of pictures/prints and wait patiently for the stamp fairy to deliver, then the supressor transfers to you. $700 for this legacy OSS and the fact you will now have an MR762SD. More pics on request, PM me if you have any questions. bviou Edited 21 Aug 2019 by MEW Naples, Florida, United States Share this post Link to post Share on other sites
