Back in April of this year, Biden decided to take aim at the so-called “Ghost Gun” industry. This is what he had to say:
So the ATF decided to take aim at the DIY gun kits like the GST-9. As a result of this, they declared that selling an 80 percent firearm frame complete with all of the parts needed to turn that frame into a firearm is constructive possession and violates Federal law.
As a result, kit makers can’t put everything needed to turn an 80 percent frame into a firearm into the same box. So now they put them into two boxes, meaning that the rails for a Glock frame can’t be included in the same box as the rest of the (unfinished) frame. So now the rails come with the jig, which you must order separately.
Due to recently changed ATF regulations, we cannot legally include the jig or frame rails with the GST-9 frame. The jig and GST-9 frame must be purchased on our website as two separate items. Each jig includes one set of GST-9 frame rails. You will need to purchase one jig for every GST-9 frame you plan to build. Frame rails are ONLY included with the jig, not with the 80% lower itself.https://www.80percentarms.com/products/gst-9-80-pistol-build-kit/
The jig with the rails can be in the same order as the frame and even ship at the same time, thus proving that efforts to control this industry are doomed to failure.
