re: #213 wilburs

why not
it worked with the Sig Sauer M400

Big difference. The M400 is an AR-15 type semi-auto rifle, and as such is considered a Class 1 firearm by the ATF. Allowing it to be imported required only a change in ATF regulations.

Land mines, by contrast, are considered Destructive Devices under the National Firearms Act of 1934 (as amended by the Gun Control Act of 1968), and further have been listed such that they cannot be purchased by civilians at all, even in deactivated form. To allow them to be used in a hunt would require an Act of Congress.
