You reckon if a FFL "designates" your Glock as a "long gun" you can put a stock and a forward grip on it? How about he "designates" your 10/22 as a "hand gun", then you can cut the barrel down to 6 inches and add a pistol grip? Yeah right.
The classification of the firearm is determined by it's actual state as configured at first retail sale. Even a correct designation does not determine how you may configure it, let alone an incorrect one. A used lower, for example, is to be notated as "other firearm", just like a virgin one, but it would not be legal to make a pistol from it if it had actually began life as a rifle.
I'll repeat, what an FFL puts on a 4473 either
correctly or incorrectly does not actually determine the legal classification of a firearm, and/or the legality of future configuration of it.
I am not shocked that the OP said his FFL marked the lower as "long gun" in field 18, but he says he also wrote "rifle" in field 29, rather than "AR receiver", "AR lower" or whatever -- I would think that would be seen as an outright lie, and subject to have FFL revoked, and doubly so if he entered it in his bound book the same way.
