After you have your rifle setup, and ammo, training, optics, plates, sustainment, NV, thermal, etc etc, there's nothing really left to do. Honestly, you hit diminishing returns on the return on investment pretty quick.
But three extra rifles to hand out let you quadruple the rounds you can put down range, cut the chances you're the target of returning fire by 75%. Three extra rifles will costs less than a lot of what a lot of you are thinking of buying 'next'.
If you want to go fast, go alone. If you want to go far, go together.
