The .17 HMR (Hornady Magnum Rimfire) cartridge, known for its impressive accuracy and flat trajectory, has gained significant popularity among enthusiasts. This popularity has fueled a demand for reliable and high-capacity magazines compatible with AR-platform rifles chambered in .17 HMR. While not as ubiquitous as AR-15 magazines in more common calibers, several options exist, each with its own set of advantages and disadvantages. This guide will delve into the world of 17 HMR AR magazines, exploring the available choices, factors to consider when purchasing, and potential modifications.
Understanding the Challenges of .17 HMR AR Magazines
Before diving into specific magazine options, it's crucial to understand the inherent challenges in designing a reliable .17 HMR magazine for an AR platform. The smaller, lighter .17 HMR cartridge requires a different feeding mechanism compared to larger calibers like .223 Remington or 5.56 NATO. This often leads to less robust designs and a higher potential for malfunctions, such as feeding issues or failures to feed.
Furthermore, the AR-15 platform, while incredibly adaptable, wasn't originally designed for the .17 HMR cartridge. This means manufacturers often need to employ creative solutions and specialized designs to achieve reliable functionality. Consequently, the variety of readily available magazines is smaller than for more established calibers.
Available 17 HMR AR Magazine Options
Currently, the market offers a limited but growing selection of 17 HMR AR magazines. Research into specific manufacturers and models is critical, as availability and reliability can vary. Look for magazines that are constructed from durable materials like high-impact polymer and feature precise feed lips for consistent and reliable operation.
Factors to Consider When Choosing a Magazine:
- Capacity: While higher capacity is generally desirable, reliability should be prioritized. A smaller capacity magazine that feeds flawlessly is far superior to a larger one that frequently malfunctions.
- Material: High-quality polymers are essential for durability and resistance to impact. Metal magazines might offer added robustness but often at the cost of increased weight.
- Feed Lip Design: The feed lips are crucial for reliable feeding. Look for designs that demonstrate smooth and consistent feeding in testing and reviews.
- Manufacturer Reputation: Choose magazines from established and reputable manufacturers with a history of producing quality firearms accessories.
- User Reviews: Always check online reviews from other users to gauge real-world performance and reliability.
Potential Modifications and Customization
While ready-made 17 HMR AR magazines are available, some users explore modifications to improve feeding or function. This is an area requiring significant expertise and caution. Improper modifications can render the magazine unreliable or even unsafe.
It’s strongly advised that only experienced gunsmiths or individuals with extensive knowledge of firearm mechanics attempt magazine modifications.
Conclusion: Choosing the Right 17 HMR AR Magazine
Selecting a reliable 17 HMR AR magazine requires careful consideration of several factors. Prioritizing reliability over sheer capacity, choosing a reputable manufacturer, and reviewing user feedback are all crucial steps in the process. Remember that consistent function is paramount, and while high-capacity magazines are attractive, a flawlessly functioning smaller capacity magazine will prove far more useful in the long run. Always practice safe gun handling and consult with experienced gunsmiths or professionals if you have any doubts or questions.
