Frequently Asked Questions
What types of ammunition can the Mossberg 590A1 M-LOK fire?
The 590A1 M-LOK features a 3" chamber, meaning it is compatible with standard 2¾" and 3" 12-gauge shells. This includes birdshot, buckshot, and slugs — making it equally capable for home defense, tactical use, and range training. Avoid steel shot unless the choke and barrel are specifically rated for it.
What accessories can I attach to the M-LOK forend?
The M-LOK slots on the forend allow you to attach a wide range of compatible accessories directly, including weapon lights, pressure switches, rail sections, and vertical foregrips. M-LOK is an industry-standard mounting system, so you'll have a broad selection of aftermarket options from brands like Magpul, Arisaka, and Streamlight.
How does the 590A1 differ from the standard Mossberg 590?
The 590A1 is Mossberg's military-specification variant of the 590 series. Key upgrades over the standard 590 include a heavier-walled barrel, a metal trigger guard (vs. polymer), a metal safety button, and a parkerized or matte finish on metal components for enhanced corrosion resistance. These enhancements make the 590A1 the preferred choice for professional and high-volume tactical use.
