I put it in the middle of the same mold and fill it up with aluminum - have I made a complete lower? Now take it one more -- that same piece of aluminum with the pegs is a different color than the aluminium I am going to use to fill the mold. When I fill the mold have I created a complete lower? You can see the two distinct colors - one looks like an odd square with some cylindrical rods coming out of it, the other color looks EXACTLY like a completed lower.

    Chemically the two different colors are the same material - they are bonded at the molecular level. So how is it that the piece that is one color is any different from the piece that is another color?

    Instead of an all poly lower, how about; I take a billet, cut the trigger control out, then fill it with a poly substance (easy removal later); I will then finish the lower. At no point has it ever been a "Complete" lower. Should work! Anyone want some 80% poly filled lowers??

    For those on facebook you should like Ares page. Pretty funny stuff they have been posting. They have taken video stills from the raid and been captioning them with some pretty funny stuff. Making fun of the ATF "Operators".

    Probably not helping their cause as far as the ATF is concerned but funny just the same. They appear ready to fight this all the way and are not backing down at all.

He then uses a screwdriver to separate the white filled-in pocket from the lower. calguns.net has a thread on this.
    A difference in the plastics will provide the limited bond between the two. It says nothing of which part came first. You would need to explain to me how to mold the outer portion (the lower) such that the cross bands would be created for the white insert to be injected around them. From a manufacturing standpoint, it doesn't make any sense to mold the outer portion first.

    No, I didn't write it in a sarcastic tone. I wanted to see what the reply's would be; now that it was taken sarcastic, that gives me some indication that it might not be OK to do 80% this way. lol

    It would not be OK because a little heat would remove the poly without damaging the AL.

    Much like if the two plastics in OP react to different chemicals and it is possible to dissolve the filler. At some point the work required is too small and the ATF gets to make all the rules.

    I think about this every single time someone shoots a video in portrait mode.

    I heard some guys talking about this raod on the Ham radio this morning. One of them apparently purchased theblower and was worried about the ATF showing up to collect.

    So, this story is totally unrelated (about the French forcing half their drivers to stay at home one day), but the line from their transport minister is chilling, as it's what many gov't bureaucrats want to say I think:

    "This is a public health problem ... we thank everyone who fell into line," Transport Minister Frederic Cuvillier said. (emphasis added)

    Imagine the ATF from this story doing the same. Like I said, chilling.

    I bought some blocks of aluminum from these guys. But I gave them all away as presents. They make really good paperweights for desks.
