From Ammoland:

There are homemade firearms.  There might even be DIY guns.  But there are no such things as ghost guns.  We don’t use the term “assault weapon” in place of a semi-auto rifle, do we?  No, we quit that nonsense.  We even try to resist “high capacity” for normal magazines, as we know a Glock 17 was designed to house 17 rounds of ammunition in the standard magazine, not 10 or 7 or less.
