I was looking at the SG cause I recently became a dealer for thopmson machine and already have a few of their suppressors and love them. Plus TM are great to deal with and I was looking for a large volume can for the shop mp5. I have acces to any suppressor/mount combo I want. TM has earned my business as they don't have the issues I have sealed with from the 3 letter companies (AAC, SWR, AWC), and I can buy two TM suppressors for one of the other brands....
