Kings was a 2009 US television drama that aired for 13 episodes on NBC. The series was loosely based on the Biblical story of King David, but the setting moved to a country resembling the modern day United States (the series was filmed in New York City). The cast included Ian McShane, Christopher Egan, Susanna Thompson, Sebastian Stan, and Eamonn Walker.
The following weapons were used in the television series Kings:
David Shepherd is seen carrying a Beretta 92FS when conducting a rescue mission in "Goliath, Part 1" (S1E01).
Smith & Wesson M&P
Though David Shepherd uses a Beretta 92FS in the pilot, the other Gilboan soldiers throughout the show are seen using Smith & Wesson M&Ps as their sidearms. The use of these pistols, along with the Smith & Wesson M&P15 Tactical rifles, suggests that the Kingdom of Gilboa seems to have adopted Smith & Wesson firearms for their military.
In "New King, Part 1" (S1E12), a Glock 17 is used in an assassination attempt.

Smith & Wesson M&P15 Tactical
The Smith & Wesson M&P15 Tactical appears to be the standard-issue infantry rifle of the Kingdom of Gilboa's Army, and is seen in the hands of various soldiers including Captain David Shepherd (Christopher Egan). Most of the rifles in the series are fitted with EOTech 553 holographic sights. At the time that the show aired (2009), the M&P15 Tactical and its free-floating continuous quad rail were fairly new to the market, making the appearance here the earliest in a film or television series.
While most of the firing M&P15 Tactical rifles in the series have 16" barrels, the series also features non-firing rifles which have shorter 14.5" barrels; it's likely that the latter are King Arms S&W MP15 airsoft replicas.
The JP-15 appears to be the standard weapon of the Gilboan palace guards.
Norinco Type 56-1
Soldiers fighting for the Kingdom of Gath are armed with Norinco Type 56-1 rifles fitted with railed top covers and handguards.
Blaser R93 Sniper Rifle
In "Prosperity" (S1E03), a Gilboa military sniper is armed with a suppressed Blaser R93 LRS2 when dispatched by General Abner (Wes Studi) to assassinate David Shepherd. The integral non-picatinny scope mount gives it away as an LRS2 as opposed to the R93 Tactical2.
M240B Machine Gun
The "Goliath"-class tanks of Gath appear to have the M240B mounted on top of the turret.
In "Goliath, Part 1" (S1E01), David is seen using a fictionalized version of the M136 AT4. This version is seen to be able to be reloaded instead of being a one-shot only weapon.
