G&G have shared details of the SS-100 Mock Suppressor:
Our crocodile-etched mock suppressor provides a unique look without needing any tools. Standard threading allows the SS-100 Mock Suppressor to be easily installed onto any 14mm CCW outer barrel. The heavy-duty Aluminum-alloy construction can be used as a custom addition to any replica or to conceal a longer inner barrel while giving your rifle an aggressive look. Now available worldwide, contact your local G&G Authorized Dealer for pricing and availability..
