Boss (1975) [Blu-ray + DVD]

Boss has "decided to hunt white folks for a change," by becoming a bounty hunter to click the hammer on fugitive outlaws. He and his comic sidekick Amos (D'Urville Martin) ride into the town of San Miguel, find it has no sheriff, and takes the job himself, much to the displeasure of the racial epithet-hurling townsfolk who must pay $20 each time they use the "n-word."
