The 828 U triggers reset when the top lever is unlocked instead of by opening the barrels on a traditional over/under-creating a smoother, more consistent opening action. In addition, the ejector system in the 828 U is all contained in the barrel. This design allows for a stronger, more streamlined receiver by eliminating the need for linkages between the trigger group and the forend. Benelli's patented steel locking system eliminates wear and tear on the receiver and hinge that cause traditional O/U's to fail. The heart of Benelli's Steel Locking System is a solid steel breech block that locks directly to the monoblock, containing all pressure from the shotshell and preventing its transfer to the receiver and hinge pins. - CHAMBER 2-3/4", 3" - CHOKES Crio(R) - C, IC, M, IM, F - SIGHTS Red, fiber-optic front
