Jane’s Book of Small Arms
The second amendment says arms. Doesn’t say bolt action rifles, revolvers, shot guns, semi automatic firearms, fully automatic firearms, RPG’s, etc. It says arms.
Small arms is any weapon system designed to be operated by a single person. Large arms are operated by team or group.
The second amendment was not written to limit what an individual may own, carry or use. The second amendment was written to ensure that the individual would be on par with the government.
I do not see where the second amendment differentiates between small or large arms.
