Mas Defense

Mas Defense, So I emailed Mas Defense about buying the Geisler defence 19x frame and Jig and drill bits together because thats how its advertised and they sent me a email confirming they Send The Geisler Frame 19x With Jig and drill bits. I also emailed Moriarti Armaments, Gorilla Machining and Limitless America if they do this and all 3 told me its VERY illegal to sell Geisler frame the way Mas defense is.. I was told that ANYONE Who buys from them will end up getting rated by the Feds because of a Federal law that took effect in 2025. i was told the feds will get all the Illegal frames sold after 2025 order!! I even googled it and get a answer its illegal but its rocky... Mas Defense is only company selling like this.. Reason of post is because I want a professional opinion is this illegal or okay to do? Mas defense did get over on me so be careful.
