Saw an Auto Ord .45 M28A1 semi for sale with the correct looking (but short 11"0 THompson barrel. The receiver was marked Auto-Ordnance and semiautomatic.
How does the SBR reg work.
Is a regular receiver with a dummy barrel still an SBR (e.g. using the analogy for MGs where it is the receiver that is the MG, not the barrel)?
Could you own a A-O receiver that is fully functional and a dummy 45 cal barrel and not have it be an SBR if you don't own the short barrel?
Curious!!!!
