The Winchester Model 70 is a legendary rifle, prized for its accuracy and reliability. However, one common complaint among owners is the proprietary nature of its magazines. Many shooters find the standard Model 70 magazines less convenient or adaptable than the readily available and often more affordable Hunter-style magazines. This guide will walk you through the process of converting your Winchester Model 70 to accept these popular alternatives, covering various considerations and potential pitfalls along the way.
Understanding the Conversion Process
The conversion involves replacing the existing magazine box and floorplate of your Model 70 with components designed to accommodate Hunter-style magazines. This isn't a simple drop-in replacement; it requires some disassembly and potentially minor modifications, depending on your rifle's year of manufacture and specific model. Crucially, this process may void your firearm's warranty, so proceed with caution and at your own risk.
Identifying Your Model 70
Before starting, accurately identify your Winchester Model 70's year of manufacture and specific model. Pre-64, post-64, controlled round feed (CRF), and other variations have differences in their magazine well designs. The compatibility of aftermarket parts varies widely between these versions. You can usually find the date code stamped on the receiver. Online forums and Winchester's website can help in identifying your specific model if you're unsure.
Necessary Parts and Tools
You will need the following:
- Hunter-style magazine conversion kit: These kits typically include a new magazine box, floorplate, and possibly other small parts depending on the manufacturer and your rifle model. Reputable manufacturers are crucial here, as poorly made parts can lead to malfunctions. Research brands carefully.
- Screwdrivers: A variety of screwdrivers (Phillips and flathead) will be needed for disassembly.
- Punch: A brass punch is recommended for removing pins. A metal punch risks damaging the receiver.
- Gunsmithing tools (optional): If modifications are needed (rare, but possible), you may require specialized gunsmithing tools. If you lack experience, consider seeking professional assistance.
- New magazines: Purchase several Hunter-style magazines compatible with your chosen conversion kit.
