These guys market this like they are doing the Lord’s work:
Watching that guy pull the trigger was painful. Slappy Mc2ndKnuckleSlapperson.
Maybe I’ll eat my words when someone says they printed that out on a $200 RepRap, but my guess is they have some sort of fancy printer similar to the $20,000 one Stratasys yanked their lease on. If that’s the case, color me unimpressed. I had perfect 3D CAD drawings of the AR-15 lower 7 years ago… they didn’t invent that shit. Oh what they reinforced it in a couple places? *yawn*
I do support the Defense Distributed concept/project as a whole, but using boutique equipment and then humble bragging about the results is the part that doesn’t impress me. As people have pointed out before, printing an AR lower out of plastic is cute and all, but I’m sure a lot of people who are shitting a brick over this don’t ever realize that you can make machine a billet aluminum ar-15 lower perfectly well using <$1000 worth of equipment bought from Harbor Freight. Sure it’s not quite as easy as “hit print and come back in xx minutes”… but it wouldn’t exactly take a tier 1 machinist to pull it off.
Thoughts?
