Made to quiet airsoft gun along with making them look even better. It is your responsibility to print responsibly and to not break the law. Without the filing of a form 1 and a $200 tax stamp it is a federal offense to make or have a suppressor for real firearms without registration. This is not designed to hold up to the pressures anything greater than pistol rounds, but should be used for airsoft ONLY. That being said it works remarkably well on all of my guns. print with threads down with 20% honeycomb infill and with support. support material will act as steel wool in theory and help absorb vibrations.
