I saw those same build kits, and knowing nothing really about them except the general concept of build kits it had me wondering what the draw is, as I can buy the real thing cheaper than the kit. Is it just having a gun off the books? Or is there some other build kit benefit I'm missing? I'm genuinely curious about the draw to them.
I really don't know what the draw is, to some I'm certain its the no background check. In fact a number of the guys I witnessed buying the kits didn't "appear" to be the type that spend a lot of time doing things legally, but I never paid much attention to them.
Now that they are on the endangered species list, I thought I would take a look before they are gone. I like building things, myself so there is some draw there.
