In regards to block 8b has anybody had any recent success in "registering," for FFL/SOT SBR purposes, in multiple calibers and barrel lengths by putting the multiples into the additional description box? Example fill out the form normally as SBR, 5.56, 10.5"/30" and then add 9mm/.300BLK/.22LR & 7.5",8",11.5",12.5" into the additional description.
