What’s Included
- Hastings Paradox fully rifled 12-gauge replacement barrel for Ithaca Model 37 with 3 inch chamber and barrel-mounted cantilever plate
Designed as a slug barrel for the Ithaca Model 37, this Hastings Paradox barrel is fully rifled and purpose-built for accuracy with slugs. The Model 37 barrel lug and "M37" shank stamp confirm fitment to the Model 37 platform.
The 3 inch chamber is clearly indicated by the "SPECIAL STEEL 12 GAUGE SHELLS 3" rollmark and the C.I.P.-style "18.376" marking, which denotes nominal 12-gauge bore diameter and a 76 mm (3 inch) chamber. This is a steel barrel with a durable blued exterior finish.
A barrel-mounted cantilever plate is installed, providing a stable mounting interface on the barrel itself. The barrel is supplied without iron sights or a front bead, aligning with its dedicated slug-barrel configuration.
Branding and proofs include a partial "PARA..." rollmark consistent with Hastings Paradox identification, crowned proof marks, and the noted "18.376" marking. The fully rifled bore is a core feature and is specifically configured for slug use.
