You are right no doubt but as was stated previously it is hard to have constructive intent without owning the host weapon as well. Since a lightning link or drop-in auto sear is considered the machinegun by the ATF, and those items are serialized and transferred as full auto machine guns, no...
Yeah I liked it, although my girlfriend also had a standard FNP45 and it shot just as well. For the novelty of a MRDS and FDE I paid more (see pic, I am fully on Team Brown haha) but given the choice between a black tactical and a regular FNP I would go regular all day long. Same gun really.

"Can be used with .177, .20, .22, and .25...can also be used with rimfires"
This guy is asking for jail time!
A lightning link is the same as a DIAS as far as the ATF is concerned: you can't make them nowadays, you can't buy any that were made after the 1986 cutoff date, and each one is serialized. For all intents and purposes it is a registered machinegun in and of itself. This applies to everyone...
