Yes, certain Blaser barrels, particularly those found on specific shotgun models, are indeed chrome lined. This includes models such as the Blaser F16 Game 20-bore, which features hammer-forged, chrome-lined barrels with solid joining ribs extending their full length.
Understanding Chrome Lining in Firearm Barrels
Chrome lining refers to a thin layer of chromium applied to the bore of a firearm barrel. This process significantly enhances the barrel's properties, offering several advantages, especially for shotguns and high-volume shooting applications.
Key Benefits of Chrome-Lined Barrels
The application of a chrome lining provides substantial improvements to a barrel's performance and longevity:
- Enhanced Durability: Chrome is a very hard material, which helps the barrel resist wear from projectiles passing through and extends the overall lifespan of the barrel.
- Superior Corrosion Resistance: The chromium layer acts as a protective barrier against rust and corrosion, which can be caused by moisture, humidity, and the corrosive byproducts of ammunition combustion. This is particularly beneficial for barrels used in varied weather conditions or those that might not be cleaned immediately after use.
- Easier Maintenance: The smooth, hard surface of chrome makes the barrel much easier to clean. Fouling, lead, and plastic wad residue adhere less readily, simplifying the cleaning process and reducing the time and effort required for proper maintenance.
- Improved Consistency (for shotguns): In shotgun barrels, chrome lining can contribute to more consistent shot patterns by maintaining a uniform bore surface, which reduces friction and ensures smooth passage of the shot column.
Blaser's Barrel Manufacturing
Blaser is known for its precision engineering, and their barrels are often hammer-forged. Hammer forging is a manufacturing process that shapes the barrel around a mandrel by external hammering, resulting in a highly durable and precise bore. When combined with chrome lining, this process produces barrels that are not only exceptionally strong but also highly resistant to wear and corrosion, ensuring long-term reliability and consistent performance.
Chrome Lined vs. Unlined Barrels
Here's a brief comparison of key characteristics:
| Feature | Chrome-Lined Barrel | Standard Steel Barrel |
|---|---|---|
| Corrosion | High resistance to rust and chemical damage | Moderate resistance; more prone to rust |
| Cleaning | Easier, less fouling buildup | Requires more thorough and frequent cleaning |
| Durability | Extended barrel life, resists wear | Standard wear and tear over time |
| Maintenance | Lower, less demanding | Higher, more critical for longevity |
| Cost (Initial) | Potentially higher | Generally lower |
For shooters seeking maximum durability, ease of maintenance, and reliable performance over many years, chrome-lined barrels offer a significant advantage.
