I have one of these sitting at my OR dealer but I keep buying 9mm cans aranoid: Don't want to sell it but if someone has something cool to trade.. it will still cost you $50 xfer and $200 tax stamp.. all NFA rules apply.. DeGroat Tactical Armaments, LLC. received a Military/Government Order to design and manufacture three different models of 9mm suppressors, which went to Iraq for combat use. While we were in the process of filling that order we manufactured extra parts so we could also offer these suppressors to the Civilian and Law Enforcement market Length= 7.30" Diameter= 1.25" Weight= 9.2 ounces Material= Aircraft Grade Aluminum and Heat Treated Stainless Steel Suppressor Finish= Type III Hard-Coat Anodized (black) and YAG Laser Engraved.
