What's in the Box Benelli 828 U 12 Gauge Shotgun with Satin Walnut Stock and Engraved Nickle Plated Receiver Additional Chokes: C,IC,M,IM,F Shim Kit Hard Case Owner's Manual 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. 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. The Progressive Comfort System is contained within the 828 U walnut stock (shown in the cutaway images here). The flexible and lightweight polymer buffers compress to absorb recoil energy. The heavier the shot load, the more buffers come into play to help absorb and cushion the recoil.
