re: #21 Quoth the raven, Covfefe.

Oh, you can print a working AR15 - you might get 2 shots out of it, if you’re lucky. If you’re unlucky, it’ll blow in your face and you’ll have a gunpowder tattoo and an eyepatch.

The printed “AR-15” is the lower receiver. The only serial numbered part. Upper receivers, barrels, trigger groups can be purchased online/through the mail with no background checks.
