The .17 HMR (Hornady Magnum Rimfire) cartridge has gained significant popularity among hunters and plinkers for its impressive accuracy and flat trajectory at extended ranges. Its use in AR-style platforms adds another layer of versatility and appeal. However, finding the right magazine for your 17 HMR AR can be more challenging than with more common calibers. This guide will explore the options available, key factors to consider when choosing a magazine, and some common troubleshooting tips.
Understanding the Challenges of 17 HMR AR Magazines
Unlike the readily available magazines for AR-15 platforms chambered in 5.56 NATO or .223 Remington, the market for 17 HMR AR magazines is considerably smaller and more specialized. This scarcity stems from several factors:
- Smaller Market Demand: The .17 HMR, while popular, isn't as widely adopted as the more established calibers used in AR-platform rifles. This translates to lower manufacturing volumes and consequently, fewer readily available options.
- Magazine Design Complexity: The smaller .17 HMR cartridge requires a more intricate magazine design to ensure reliable feeding and prevent malfunctions. This adds to the manufacturing cost and complexity.
- Limited Compatibility: Not all AR-15 lowers are compatible with .17 HMR magazines. Some modifications might be necessary, depending on the specific lower receiver and magazine design.
Types of 17 HMR AR Magazines Available
While the selection is limited compared to other calibers, several types of 17 HMR AR magazines exist, each with its own pros and cons:
- Rotary Magazines: These magazines offer higher capacity than traditional box magazines, but they can be more complex and prone to malfunctions if not properly maintained.
- Box Magazines: These are the most common type of magazine, offering a balance between capacity and reliability. Capacity typically ranges from 10 to 25 rounds, depending on the manufacturer and design. Pay close attention to the manufacturer's specifications for compatibility with your specific rifle.
- Specialty Magazines: Some manufacturers might offer specialized magazines designed for specific AR-15 lowers or featuring enhanced features like improved feeding or dust covers. Research carefully to find the correct magazine for your rifle.
Factors to Consider When Choosing a 17 HMR AR Magazine
Choosing the right magazine is crucial for optimal performance and reliability. Here are some key factors to consider:
- Capacity: Balance the desired capacity with the weight and potential for increased malfunctions that can arise with higher capacity magazines.
- Reliability: Look for magazines known for their consistent feeding and reliable operation. Read reviews from other users to gauge the reliability of a specific brand or model.
- Compatibility: Ensure the magazine is explicitly compatible with your specific AR-15 lower receiver and upper receiver group chambered in .17 HMR. Manufacturers' specifications will usually clearly state compatibility.
- Material: High-quality materials, such as durable polymers or steel, contribute to the magazine's longevity and performance.
- Price: While price shouldn't be the sole deciding factor, it's important to consider the cost relative to the magazine's quality, features, and reliability.
Troubleshooting Common Issues with 17 HMR AR Magazines
Even with high-quality magazines, you might occasionally encounter issues. Here are some common problems and potential solutions:
- Feeding Problems: Ensure the magazine is correctly seated in the lower receiver. Clean and lubricate the magazine and feeding mechanism regularly. Inspect the magazine for any damage or debris.
- Jamming: Check for obstructions in the magazine or the rifle's action. Ensure the ammunition is of high quality and properly lubricated.
- Magazine Not Seating Properly: Inspect the magazine well for any obstructions or damage.
Conclusion
Finding the right 17 HMR AR magazine may require some research and careful selection. Understanding the factors discussed above, including capacity, reliability, compatibility, materials, and price, will significantly improve the odds of finding a magazine that flawlessly integrates with your rifle, delivering consistent and reliable performance. Remember to always prioritize safety and practice responsible gun handling.
