The Remington Model 10 is a pump-action, 12-gauge shotgun designed in the United States. Although the M97 Trench Gun was the main issue shotgun of US troops during World War I, around 3500 Model 10-As, modified with a shortened barrel, sling swivels, a wooden heat shield and a bayonet lug, were delivered for use in the conflict.
— In-game description
The Model 10-A is a weapon featured in Battlefield 1.
In the War Story, The Runner, the main protagonist, Frederick Bishop, wields a variant called the Model 10-A Sweeper. It's unknown what makes this variant different from the others, though if the duckbill choke were to indicate anything, it would mean that it should function similar to the M97 Trench Gun Sweeper.
The Sweeper variant can also be found in a weapon crate in the War Story, Through Mud and Blood.
Three variants are featured in multiplayer: Factory, Hunter and Slug.
The Model 10-A Factory is the base variant of the weapon, featuring no attachments aside from the standard ability to change the zoom level and whether or not to equip a bayonet. Like all Factory variants, this gun can regain accuracy quicker due to it's lower weight.
The Model 10-A Hunter variant is effectively an upgrade of the Factory version, as it has a special choke to tighten the spread of the buckshot. This allows the gun to be deadly at longer ranges while keeping the raw damage intact.
The Model 10-A Slug variant uses slugs as its ammunition type, reducing raw power for a vast improvement in mid-ranged combat. Hip-fire accuracy is reduced for an increase in aimed accuracy. It is also equipped with a lens sight.
