Mossberg 590A1 Magpul Shotgun
Mossberg's New 590A1 Features Magpul Shotgun Upgrades

O.F. Mossberg & Sons has been making tactical shotguns for many years, and the company’s 590 series is the choice of the U.S. military. Built tough with a 20-inch, heavy-walled barrel and a Parkerized finish, the gun is meant to stand up to harsh use. But Mossberg has made the 590 even better by adding several Magpul extras to create the Mossberg Magpul 590A1.

There is no doubt that shotguns kick hard and many—including cops—don’t like to use them. When you don’t like a particular weapon, it’s not very likely that you’ll be good with it because you won’t practice. But the Magpul features make this gun user friendly and easier to shoot.

Built on the 590 base platform, it’s a 12-gauge shotgun with a 3-inch chamber. At the rear is a Magpul SGA buttstock that provides a comfortable grip angle, making it easier to support the gun while loading with the off-hand. Two cheekpieces come with the stock: one straight and one raised to elevate the line of sight for use with optics. The stock also has a very effective recoil-reducing buttpad, making it a lot more comfortable to shoot for extended training sessions. The length of pull can also be adjusted by 2 inches.

There’s also a Magpul Forward Sling Mount and an SGA Receiver Sling Mount, because a shotgun needs a sling like a pistol needs a holster. On top of the receiver, Mossberg installed a Picatinny rail in case the owner wants to use an optic instead of the XS Sight Systems ghost ring rear and blade front sight.

The standard forend has been replaced with a Magpul MOE forend that accepts rails to mount accessories like tactical lights. And the forend sports hand stops at the front and rear to keep the hand from sliding at a critical moment.

We took the Mossberg Magpul 590A1 to the Gunsite Academy to give it a hard workout and see just how well it handled. Check out the video to see how it performed, and keep your eyes peeled for a full test and evaluation in an upcoming issue of TACTICAL WEAPONS. To subscribe, visit
