Just had to give a shout out to Cascade Arsenal and their great customer service! I purchased a SWR Specter ll from Chip at Cascade and recently just got my paperwork and stamp back. They handled everything and made the process so easy. I cant wait to buy another suppressor from them! If your looking for a suppressor this is the place to start! Look for him at the WAC shows. The SWR Specter ll is so quiet is scary.
