So... Originally polymer 80 sold just the frame with the disposable fixture and drill bits. IIRC, anyway. That's how they got their original "this is not a gun" approval from the ATF?
Then they started selling parts?
Then they started including parts?
Eventually selling a kit that required 20 minutes with a dremel and nothing else.
Can anyone here comment on the increasing commonality of finding 80% guns at crime scenes with the increasingly turn-key kits? That would seem like an interesting frame of reference.
It may seem like a small detail but without a complete kit I can easily see a whole bunch of morons trying to buy "glock parts" and ending up with incompatible gen4 or whatever internals that wouldn't result in a working gun. The turn key nature adds a lot to the "readily convertible" angle.
I wonder if the next step was full color ads in Inmate monthly magazine. Not because they actually want to sell to felons but because some people in this industry have such a hard on for playing fuck fuck games with the ATF they don't know when to quit.
