Replacing the barrel on your Stevens 320 shotgun can seem daunting, but with the right tools and knowledge, it's a manageable task. This guide provides a step-by-step process for safely and effectively replacing your Stevens 320 barrel, covering everything from choosing the right replacement to the final assembly. We'll also address common issues and safety precautions.
Understanding Your Stevens 320 Barrel
Before you begin, it's crucial to understand the specific model of your Stevens 320. Different models may have slight variations in their barrel assembly, so referring to your owner's manual is essential. Knowing your gauge (12, 20, etc.) is also vital for selecting the correct replacement barrel. Always double-check compatibility before purchasing a replacement barrel.
Identifying Your Barrel Type
Stevens 320 shotguns are known for their versatility, often offering different barrel configurations like:
- Fixed Choke: The choke is permanently attached to the barrel. Replacement involves replacing the entire barrel assembly.
- Interchangeable Chokes: These barrels allow you to easily switch between different chokes (e.g., full, modified, improved cylinder) to optimize your shot pattern for different hunting scenarios. Replacing only the barrel may not be necessary if only the choke needs changing.
