What's Included
- Browning Auto-5 12 gauge barrel assembly
Made in Japan and Browning-marked, this barrel assembly is configured for the Auto-5 long-recoil action. The integral barrel extension and barrel ring are correct for this design, providing the required interfaces for the Auto-5 system.

Factory rollmarks read "BROWNING ARMS COMPANY MORGAN, UTAH & MONTREAL P.Q., MADE IN JAPAN" along with "NP 3" markings. These identifiers align with later-production Auto-5 components manufactured in Japan.
