Hi Aaron,
If bought as a rifle: always a rifle
If bought as receiver, first made as rifle: always a rifle
If bought as receiver, first made as pistol: can be made into rifle and back, as long as you don't make it SBR midway through
If bought as pistol: can be converted to rifle and back, as long as you don't make it SBR halfway through
If form 1 SBR: can be changed back to non-SBR spec whether it was a pistol or rifle
Stay safe & have a great day!

Hi Aaron and welcome. Yes, but not legally. This was manufactured complete with a shoulder stock and will transfer as a Rifle Lower. Cheers, stay safe and enjoy!
