Fully 3D printed Liberator suppressors are available in 22 caliber and 36 caliber versions for 22lr, 22 short, 380 acp, 9mm, etc. These suppressors are also available in several lengths and are rated for subsonic ammo only. Standard PLA is a suitable filament for these suppressors, and since the liberator is single shot, they wear extremely slow, if at all, making it possible for them to last indefinitely. These suppressors connect to a modified Liberator barrel that is threaded. Before use, this threaded plastic barrel must have a metal pipe or metal barrel installed into the center, straight and level, or else the plastic barrel will fail when shot and possibly cause injury. Before printing these suppressors please read the "README" text document that is in the folder along with the files. NOTICE: All United States persons must purchase a $200 Federal Tax Stamp as well as file a Form 1 with the Bureau of Alcohol Tobacco and Firearms before assembling this suppressor. It is illegal to assemble this suppressor without following these steps.
