Hello All, I just picked up my very first AR lower from a local FFL. I ordered one of the Palmetto State Armory Complete AR lowers they had on sale. This lower includes a stock already assembled from Palmetto. The local FFL had me fill out a 4473. He said he would mark "Other" on the 4473, but now that I think of it, I didn't verify that he marked it as "other" rather than "pistol." Though he did say that he would be marking "other." In addition to the 4473 I had to fill out a WA "Department of Licensing" pistol background check form. This seemed odd to me since what I was receiving was an AR Lower, marked Multi, that was already equipped with a stock. Federal law stipulates that once a stock has been attached, the lower from that point on is considered to be a "rifle" lower. The FFL said that as far as Washington State is concerned, it can be made into a pistol and thus this is standard practice. Doing this would violate federal law, so I'm a bit confused why this would need to happen. Is it standard practice, in Washington State, to fill out a Pistol form in addition to the 4473 when transferring a lower? Thank you.
