So, is this over 26" extended? Is that the trick? But it says "or" and it definitely has a barrel under 16", and if it is a smooth bore it's useless, or did they come up with some sort of internal configuration besides rifling to stabilize the bullet?According to the NFA an SBR is any firearm with a buttstock that has a rifled barrel of less than sixteen inches, or an overall length of less than twenty six inches. The total length is measured in the extended position.
Can't wait for the answer.
