CQS48 Bulldog

The CQS48 Bulldog, otherwise known as the CQS-48 Combat Shotgun, is a type of human shotgun manufactured by Misriah Armory in Eos Chasma. It is in service with the UNSC, being employed by UNSC forces as early as 2551. During the Battle for Zeta Halo in 2560, many CQS48 were seemingly scavenged and employed by Banished-affiliated Jiralhanae.

Design details
The CQS48 Bulldog is a pump-action combat shotgun which fires 12-gauge shells from an 7-round rotating drum. After every shot, the foregrip must be retracted and pushed forward again to work the weapon's action and rotate the cylindrical magazine into the next position. The rotary magazine allows the CQS48 to replenish its supply of loaded ammunition substantially faster than the non-detachable magazines of the M45 and M90 shotguns. However, the 12-gauge ammunition it fires is substantially smaller. The Bulldog integrates iron sights and multiple attachment rail segments on its body. The CQS48 used in 2560 features a matte black and dark grey finish.

The weapon's side contains various decals including barcode which translates to details of the weapon's manufacturer, the Misriah Armory facility at Eos Chasma, Mars and the weapon's name, CQS48 Combat Shotgun. The sides of the weapon just above the magazine contain a proof mark indicating the weapon's year of manufacture and a certification that the weapon is safe to fire with nitrocellulose-based gunpowder. In the case of the Bulldogs supplied to forces in 2560, the weapons have the proof code FK, which translates to a manufacture year of 2559.

Usage
Spartan-III Thom-A293 used a CQS48 Bulldog during the Defense of Concord in 2551. CQS48 Bulldogs originating from the, were used during the Battle for Zeta Halo in 2560.

Variants

 * CQS48 MODE MS: A modified variant of the Bulldog for extremely aggressive decontamination regimes. The chassis is treated with the latest polymer and nanomaterial coatings to inhibit biological growths and spore attachment. An orange container was integrated in the stock, and the weapon is equipped with a different muzzle.
 * Convergence Bulldog: A modified variant of the Bulldog, with drum capacity increased from 7 to 12. The weapon also has an even tighter spread, allowing for greater range and accuracy.

In-game information
The CQS48 has a ready ammo count of 7. The pickup prompt indicates that the CQS48 is a "shotgun", with "kinetic" and "spread" properties. The weapon can be fired rapidly, with a much higher rate of fire than previous shotguns in the franchise, at the expense of heavier vertical recoil during rapid fire. Unlike shotguns in the previous games, the CQS48 Bulldog is not a one-shot-kill weapon when fighting multiplayer Spartans at close range, instead requiring at least two shots to kill. However, some enemies like Unggoy can still be killed with one shot.
