Once my 5.56 (29.5") Form 1 SBR is approved, I plan on submitting a form 5320.20 so I can take it to PA to shoot. I know it is legal to temporarily change uppers on an approved SBR.
In PA, a shorter .300BO upper with an OAL of <29" is fine on an approved SBR.
My question is... Can I legally (temporarily) install the <29" 300BO upper on the SBR while in MD?
