The Remington 870 is a semi-automatic shotgun with a slight delay between shots. It uses 12ga buckshot.
The Remington 870 is a decent weapon, with each pellet having decent damage, and spray being so-so. This weapon is fantastic when trying to raid a random base without any other weapons, due to the towns usually being close-quarters, and the weapon easily getting headshots due to its spread. I definitely wouldn't recommend attempting to storm an objective with this or trying to brave the open roads with it.
