I've been seeing some cool DEWATS up for sale lately (Brens, MP40's, etc...) Real MG's with welded up chambers etc... so they cant fire.
Supposedly you can buy one without a 12.6, or any other gun license.
If this is the case then can someone explain to me why a replica of one of these guns would be considered a prohibited device, but a real one rendered inoperative is OK?
