Mossberg 590A1 SPX 9-Shot, 12 Gauge, 3" Chamber, 20" Barrel w/Ghost Ring Sights & Bayonette #50771

Standing above the standard, the Mossberg Model 590A1 is a military grade variant of this famous shotgun.  It features an aluminum trigger guard and safety, and a heavier barrel than standard 500 & 590 series shotguns, and is intended for military use under extreme conditions and rough handling

The metal trigger guard was added in response to the 3443G materials requirements, and the heavy barrel was added at the request of the US Navy. The 590A1 is generally sold through military and law enforcement channels within the USA, but suffers no restrictions inside Canada.
