The “lower” is the only part that has to be delivered via an FFL from what I’ve heard. All other parts can be delivered to my front door. If the money is about equal I would buy a complete weapon and wait to learn how to “build” one until I leave this terrible place that is New York State.
My son is having one built for him, in .300 Blackout. Lower is FFL, rest is from various places on sale. A buddy is building it for him.
The buddy suggested buying numerous lowers (FFL) now to get them before the new Washington state laws take effect which will require having taken a safety class prior to buying ANY semi-automatic rifle (including .22 plinking guns!).
Hmm - seeing as this is considered a pistol, the new requirements for the safety training class may not be needed. (It may only be for “assault” rifles. But I doubt it - probably for any firearm. Even though the law was sold as preventing evil assault rifles from getting into the hands of “kids”)
