How many AR lowers can you buy in a period of time before the ATF says "Hi"
Not looking to stock up, but I sold a lower recently and I already had an extra upper and I'm looking to add a couple KISS uppers over the winter so I thought I might get in four of the blemished Bravo lowers. Wasn't there a change recently (last year) about lowers being transferred more like pistols than like rifles on 4473s? Is there a magic number of lowers that triggers mandatory FFL notification to the ATF? Is there an unnofficial number that might peak the ATFs interest next time they peruse my FFLs books?
