Which would be better for hand to hand combat, a bayonet or a rifle

Well that would be Bayonet because:

The definition of bayonet is:

A sword like stabbing blade which may be fixed to the muzzle of a rifle for use in hand-to-hand combat

So therefore if u choose a bayonet u would also rifle

Personally, I would choose a bayonet in a hand to hand combat fight. Rifles are just for a far distance. If the person is close to you they can easily take it from you but then if it's a bayonet and you know how to use it then they won't take it from you unless they are some bad a* * people.
