What’s Included
- J. Stevens A&T Co Model 520 12 Gauge pump-action shotgun
The receiver shows the classic Model 520 double-hump contour and carries the early J. Stevens Arms & Tool Co. rollmark alongside Browning patent dates, marking this as a pre-1916 example. The action bar is marked "520," aligning with early production details valued by Model 520 enthusiasts.
It features the pump-action takedown system with a collar, allowing the barrel and magazine assembly to separate from the receiver for transport or maintenance. The magazine tube runs out near the muzzle and is secured by one barrel/magazine ring, consistent with period construction.
The action slide tube has three circular lightening holes, another hallmark of early configurations. A simple bead front sight sits on the 28-inch steel barrel, supporting quick target acquisition in a traditional field layout.
Capacity is 4+1. Major components are steel; the barrel and magazine tube retain blued finish, while the receiver and tangs are in-the-white (finish stripped/worn). Manufactured in the United States during the pre-1916 era, this configuration presents strong bones and correct early markings for a project-minded buyer.
