About the Mossberg 590A1

The Mossberg 590A1 grew out of the Mossberg 590 series and was adopted by the U.S. military as the standard combat shotgun in 1985 (Mil-Spec 3443E). Heavy-walled barrel for sustained-fire durability, bayonet lug, metal trigger guard, parkerized finish, and a heat shield handguard — the 590A1 stripped away anything that wasn’t combat-essential. The civilian version is mechanically identical to the issued military shotgun.
