high end advanced supressor if filled with sound absorbing material such as felt for example.You can print it in three parts, the hood the airstripper and the baffle part.everything in stl, obj or step format.you can also choose whether you want the cap with a thread or with a recess for placing a 1/2-20 UNF nut or a 20 x 12 mm recess for an insert with a thread of your choice.After that it is important to wrap the airstripper with felt and place it tightly in the hood.In the space between the baffles also felt but not to much.Now you can achieve very good damping for airguns up to 120 joules and possibly more without the risk of damage due to the ventilation holes.

Have fun
