I have an AR 15 and a bunch of ammo... Are you saying you own something that you’d be willing to mix it up with if I was your adversary? Doubt it.
My L1A1 against your AR-15? Depends who is the better shot.
The only time I shot at somebody I only wounded him - so you might be better than I am with a gun. But it’s not the gun - it’s the gunner if you are.
