The competition features two challenges inspired by real life SWAT team scenarios. A physically demanding individual challenge leaves three shooters exposed for nomination. And, in an extreme elimination showdown, competitors race the clock as they breach doors with the Mossberg 500 Chainsaw Shotgun to take out targets with the FN FS2000 assault rifle.

Season Four begins with the biggest twist in Top Shot history: two competitors are sent packing immediately after a surprise shoot-off in the opening minutes of the first episode. Later, two shooters get a taste of WWII combat as they fire an M1 Carbine from a motorcycle sidecar and attempt to stay in the game. Colby Donaldson returns as host.

As the field of marksmen narrows, one team holds an urgent meeting in an attempt to reconcile their differences. The team challenge features an ultra-modern, high-power crossbow that fires bolts at a stunning 350 feet per second. In the aftermath of a nail-biting archery duel, the elimination challenge is a fight to the finish with what many consider the "Perfect Pistol.

Top Shot season 2 champion Chris Reed returns to instruct the shooters on several modern shotguns. One team crumbles in the team challenge, leading to a tense nomination discussion. The final challenge is a head-to-head shotgun battle that sends one contestant packing.

Teams grapple with an explosive obstacle course and endure trench warfare conditions while firing the legendary Browning Automatic Rifle. And in a Top Shot first, two competitors duke it out in a fierce battle with a multi-shot grenade launcher.
