Frequently Asked Questions
What makes the 590A1 different from the standard Mossberg 500 or 590?
The 590A1 is Mossberg's military-grade variant, featuring a heavier-walled barrel, metal trigger guard, metal safety button, and dual extractors — all designed to meet U.S. military testing protocols. The M-LOK forend further sets this model apart by allowing direct attachment of Picatinny-rail accessories without an adapter, making it one of the most versatile tactical shotguns in its class.
What types of ammunition can this shotgun reliably cycle?
The Mossberg 590A1 is chambered for 3-inch 12-gauge shells and will reliably cycle birdshot, buckshot, and rifled slugs. The dual-extractor design and robust action handle a broad spectrum of loads — from light target loads to heavy defensive and hunting rounds — making it exceptionally versatile for both home defense and range use.
Can I attach a light or laser to the M-LOK forend?
Yes. The M-LOK slots on the forend allow you to directly mount compatible tactical lights, lasers, or other accessories using standard M-LOK hardware — no proprietary adapter required. Popular options include Streamlight and SureFire weapon lights designed for shotgun forends. Always ensure any accessory is rated for the recoil forces generated by 12-gauge ammunition.
