When submitting a Form 1 to the ATF for a SBR or SBS with multiple barrel lengths, the ATF will no longer accept a Form 1 with multiple barrel lengths. It is recommended that you submit the ATF Form 1 (5320.1) with a single barrel length for approval. Follow this link for more information on how to fill out an ATF form1 (5320.1).
