Our suppressor are designed to not handle the large amount of pressure the firearms produce. This will cause catastrophic failure of the suppressor. We do not offer our suppressors in the the threads needed for a firearm use. The internal materials used will not handle the heat from a firearm. Our suppressors are only for airguns only. The term “Firearm Silencer” or “Firearm Muffler” means any device for silencing, muffling, or diminishing the report of a portable firearm, including any combination of parts, designed or redesigned, and intended for the use in assembling or fabricating a firearm silencer or firearm muffler, any part intended only for use in such assembly or fabrication.
