That is NOT an arsenal, a personal collection maybe, but not an arsenal. Ah, Massachusetts . . .
Dude. Move to Texas. You belong here.
Must be one of them Afghanistan style weddings.
Possession of a long gun (shotgun or rifle) by an 18 year old is not a federal crime, even if it has detachable hi cap magazines. It seems Mass. has a law against rifles with hi cap detachable magazines. This state law may or may not be unconstitutional under the US Constitution (I hope so, but our Supremes are a wacky bunch).
It’s a shame to tar and feather this fine young man with a state felony just because he had this rifle. Pray that the state prosecutor uses some discretion in charging the young man. Most anti-gun laws make criminals out of otherwise honest citizens and do not affect real criminals who follow no laws.
Few bring even most of their hardware to this affairs, just their favorites. :)
