Possible reason for the gun manufacturers to lobby for the extension of the 1994 AWB

Just talking to a seller of magazines at a gun show.
He is of the opinion that the major gun manufacturers such as Ruger, Glock,
Smith & Wesson will be very actively lobbying to EXTEND the 1994 Assault
Weapon Ban due to expire next year.
The reason ?
They are facing major inventory and production costs if the ban expires
Thnk of all those 10-round mags that nobody will want ?
Think of all the guns that are already packaged with 10-round mags that will
have to be re-packaged with larger capacity magazines to meet the demand ?

Somthing to think about.
    Definitely something to take action about...
