>>1016i work at a gun range and like 1 in two dozen people use a super safety or FRT. they arent illegal as much as ATF wants them to be. further, ATF just got cut in fucking half pretty much to go work with ICE or something. i doubt they can even handle regular investigations at this time so you can forget about a fedtrap unless you are someone important.
that said i wouldnt go bragging about it online or anything, but they arent illegal. from what ive seen the super safeties work better than the standard FRTs; but you chance out of battery detonations and on top of that its just not true full auto which is nice i guess.
the short of it is, i got one, shot 4 mags through it, and meh…..i sold it
