Winchester Model 12 Field Grade Takedown 16 Gauge, 23.5 in Barrel, 2 3/4 in Chamber, Power-Pac Muzzle Device, Hawkins Pad
This Winchester Model 12 Field Grade takedown in 16 gauge pairs classic Winchester build with thoughtful upgrades. It features a 23.5 in plain round Winchester Proof Steel barrel, 2 3/4 in chamber, and a 5+1 capacity. Notable details include matching serial numbers on the receiver and barrel/receiver extension, a Power-Pac style external compensator/choke with the front bead mounted on the device, and a Hawkins ventilated recoil pad that brings the length of pull to 13.5 in. Built in the WWII era, this pump-action remains slam-fire capable due to its no-disconnector trigger.

This takedown Model 12 uses Winchester’s interrupted-thread receiver extension, allowing the barrel and magazine assembly to separate quickly from the receiver for transport and storage. The receiver and the barrel/receiver extension carry matching serial numbers, confirming the set remains together as built.
The 23.5 in plain round barrel is Winchester Proof Steel and is roll-marked "WINCHESTER PROOF STEEL," "2 3/4 CHAM.," and "MODEL 12 — 16 GA. — FULL." It feeds 2 3/4 in shells from a 5-round tube for a 5+1 total capacity. The front bead is mounted on the external muzzle device for a straightforward sight picture.
Upgrades include a Power-Pac style external compensator/choke at the muzzle and a Hawkins ventilated recoil pad at the butt, bringing the length of pull to 13.5 in. The stock and forend are walnut, with a pistol-grip buttstock and a ribbed corncob slide handle that complement the Field Grade configuration.
Core mechanical features remain true to the Model 12 design: pump-action operation with an internal hammer, a steel receiver, and a trigger without a disconnector (slam-fire capable). The shotgun bears the Winchester oval proof mark and was made in the United States during the WWII era.
