What is one key feature of the M870 shotgun?

The M870 shotgun is renowned for its versatility, which is primarily highlighted by its capability to fire both slugs and shot. This feature allows the operator to use different types of ammunition based on the tactical situation. When engaging in close-quarters combat, using shot can be advantageous for multiple targets or spread at short ranges. Conversely, employing slugs is beneficial for longer range precision shooting or harder targets that require more stopping power.

The other options do not accurately represent the M870's design and functionality. It is not a semi-automatic weapon; rather, it operates as a pump-action shotgun, which means the shooter must manually cycle the action to load a new shell after each shot. Additionally, the M870 does not feature a magazine capacity of 12 rounds, as its standard capacity varies depending on the model but typically ranges between 4 to 8 rounds. While some M870 variants might have customized optics, the shotgun does not come standard with an electronic sight, as it is primarily designed for practical use with iron sights or ghost ring sights. The emphasis on its ability to accommodate both slugs and shot aptly captures the essential functionality and versatility of the M870 shotgun.
