Key components like the bolt lock, elevator, hammer, and sear are explained in relation to their function during each stage of operation.

Quick Summary

The Mossberg 500/590 pump-action shotgun operates by manually loading shells into the magazine. Cycling the forearm moves the bolt and elevator, which lifts a shell for chambering. The bolt lock engages the barrel extension to contain firing pressure, and the trigger releases the hammer to fire the round.

Frequently Asked Questions

How does a Mossberg 500/590 shotgun load a shell?

Shells are manually loaded into the magazine tube. When the forearm is cycled, the elevator lifts a shell from the magazine, and the bolt pushes it forward into the chamber.

What happens during the firing sequence of a Mossberg pump-action shotgun?

Pulling the trigger releases the sear, allowing the hammer to strike the firing pin. The firing pin ignites the primer of the chambered shell, discharging the firearm.

How is the action locked on a Mossberg 500/590 during firing?

The bolt slide moves forward, causing the bolt lock to engage upward into the barrel extension. This securely locks the action, containing the pressure generated when the shell is fired.

What is the function of the elevator in a Mossberg shotgun?

The elevator is a crucial part of the feeding mechanism. As the forearm is cycled, it lifts a shell from the magazine tube into the path of the bolt, preparing it to be chambered.
