Mossberg 590A1 Capacity

The Mossberg 590A1 is a pump action, tube fed shotgun featuring an 8+1 capacity. Shells are loaded into the magazine tube through a loading port in the bottom of the receiver.
Weighing only 7 pounds with an overall length of 41 inches, the Mossberg 590A1 is light enough to carry at length and short enough to use through dense brush.  Its adoption by law enforcement units shows it is a formidable choice for home defense and close-quarters competition.

Mossberg 590A1 Mobility


Mossberg 590A1 Ergonomics

Based largely off of the Mossberg 500, the ergonomics of the 590A1 feel like a shotgun with a more utilitarian choice of furniture.  The ribbed composite handguard trades off surface area for texturing, and the extended magazine tube trades overall balance for capacity.

Mossberg 590A1 Fit & Finish

The Mossberg 590A1 has an alloy receiver, a blued steel barrel and internals, and composite furniture.  While the fit and finish of the metal components is well worth what you pay for, the composite furniture often has edges on the joints of the pieces where the injection molds allow excess material to creep through.  A skilled gunsmith can properly remove this defect in a matter of minutes.
