Back in 2004, I owned a Mustang Mach1, and was a member of a Mach1 forum. At the time, I was the plant manager of a manufacturing facility that provided parts to various automakers, Ford being one of them.
A member of upper management from Ford told me at a meeting that they were in the process of negotiating to purchase the rights to the "Boss 302" name, and I posted the rumor that Ford intended to some day, bring a New Boss 302 Mustang to the market. It led to a bunch of folks on the Mach1 forum calling BS and eventually the mods kicked me off the forum for defending my story.
The mods insisted I was full of C@$p because they claimed Larry Shinoda's family would never part with the rights to the name.......um, last I heard, Ford has a new Boss 302 Mustang, using the same name and graphics from the sixties.
Point is, if Colt isnt making M4's for the military, they will be converting their production to supply the civillian market, and to capitalize on the furor and paranoia in the black rifle market that is so prevalant these days.
They have begun making other iterations of old models that fell by the wayside in years past as well.
I would not be so quick to dispell rumors such as the OP posted. All indicators at the retail level would indicate that more product is coming out of Colt's factory, and that is good for us. Look for even more new models in the coming months ahead.
