Beat on the Brat: Arroyo

Beat on the Brat: Arroyo is a side job in.

Walkthrough
This is one of the more difficult fist fights, as Buck can deal a lot of damage in one punch to the point 2-3 hits on you will cause you to lose, so it's best to plan accordingly beforehand, like consuming boosters, food, etc.

When you approach to talk to him, he'll be talking about his unique rifle, O'Five. If you have at least 12 in body, you can comment on this which will then give you the option to have him also put it up for grabs, provided you have 12,000 to spare to fight him for it. Otherwise, you just need 2,900 to fight him.

Note that if you got him to put up his sniper rifle, once you win he and his buddies will turn hostile and start shooting at you. At this point you're free to also use your own guns and kill them if you wish. Once they're down, go collect the gun to complete the job.

The normal bet will end up with Buck telling you to leave if you win. You can just directly leave the area, or talk to him. You can decide whether to provoke him or to calm him down. If you decide to provoke him, Buck and his friends will proceed to attack you, and his rifle O'Five will be immediately be available for you to get.

Once they're down, go collect the gun to complete the job.
