Silver Nitride Receiver Finish
What is a Silver Nitride Finish?
Browning uses various finishes on receivers to protect steel from corrosion and the elements. While traditional bluing remains the most common choice, a silver nitride finish offers an elegant, high-end alternative.
Silver nitride gives a shotgun receiver the clean, sophisticated look of bare, unblued steel without the chance of rust and corrosion that raw steel invites — a catastrophic outcome for a premium firearm. To achieve this striking aesthetic Browning utilizes a highly durable silver nitride finish on various hunting and target shooting shotguns.
What is Salt Bath Ferritic Nitrocarburizing?
Browning shotguns with a silver nitride receiver finish rely on a specialized chemical process known as salt bath ferritic nitrocarburizing. Specifically, over-and-under shotguns crafted at the Miroku factory undergo a proprietary treatment under the trade name Tufftride.
This liquid thermochemical process diffuses nitrogen and carbon into the surface of the steel. The reaction leaves the receiver and components with a bright, silver-gray color and drastically improves the metal's resistance to corrosion and wear.
Key Benefits of Silver Nitride Finishes
- Maximum Corrosion Resistance: Protects steel against moisture, sweat, and harsh weather experienced in the field.
- Enhanced Scuff Resistance: The finish creates an ultra-hard surface layer that resists scratches and field wear.
- Improved Fatigue Wear: Boosts the structural lifespan of high-stress components under repeated recoil.
This advanced hardening process reduces shape distortion. Finely fitted Browning over-and-under shotguns maintain micro-tolerances during manufacturing that is essential to perfect lockup and smooth operation.
Controlled Liquid Ionic Nitriding
Controlled Liquid Ionic Nitriding represents the modern standard for salt bath nitriding and nitrocarburizing. This process allows technicians to precisely control the chemical bath, ensuring a perfectly uniform protective layer across complex firearms.
