Am i reading/hearing this right about muzzle breaks/shrouds

[1shotwander]

now correct me if i'm wrong. IN the USA its illegal to have a scilencer/subpressor with a background check and 200 dollars, but yet people can make them for airguns?  just under a different name...is this me or what?

Any device that is designed to reduce the noise level of a firearm, or air gun that can be used on any barrel that it will fit and can be removed and used on another gun is illegal under U.S. BATF law. An individual can apply for and pay the fee for a BATF license for use of these devices. Please check local and federal regulation. Some air rifle manufacturers have designed moderarors and shrouds that are permanently attached and have been approved for import and or sale in the U.S. on an individual model basis. GTA Forum rules prohibit the discussion of the use, sale or manufacture of sound suppressing devices. Thank you.
