Recommended Shoulder Weapon.

In this writer's opinion the most important weapon to have in your arsenal is a good shotgun. My preferred shotgun is the 12 gauge Remington 870.

The shell, I consider to be most important for the shotgun is the BB shotgun shell. This shell can be used for survival, to shoot birds for food or disabled that fool that threatens you.

If the person threatening you is a renegade former civil servant wearing body armor don't worry. The BB shot will most probably hit a part of the body not covered by armor.

The renegade will go into immediate pain and become even more distracted by you shooting him a second time.

Most important:

You will be able to dis-arm him without killing him.

Now you have that M16A2 you have always wanted.
