Wow, this thread is a new one on me.
My first reaction was "yea right, like I'm going to spend the money on a separate frame to be legal with a pistol and rifle contender.
My second reaction was, that wont get me out of the grey area anyway. If the supreme court decision only pertained to the kits, if I own a complete carbine and a complete pistol with multiple barrels, I still have parts laying around to make the rifle a pistol ,or worse, a short barreled rifle in minutes. So theoretically, the ATF could construe that as "intent" if they feel like it.
So one or the other has to go to get out of the legal grey area, or in my current frame of mind, all the contenders go, as my whole reason for owning the contender pistol was to be able to get the parts to make it a rifle to get more bang for my buck.
My third thought was, what a sad state of affairs that law abiding citizens live in fear of a government entity while engaging in law abiding, no constitutionally protected, activities.
Anyway, I'm not going to make a knee jerk reaction and sell right away, but at the moment that seems a real possibility if further research bears out the tone of this thread.
