The .17 HMR (Hornady Magnum Rimfire) cartridge has gained significant popularity among shooters for its accuracy, flat trajectory, and effectiveness on small game. Coupled with the versatility and customization options of AR-15 style platforms, the demand for reliable 17 HMR AR magazines has steadily increased. However, finding the right magazine can be tricky, as the market isn't as saturated as it is for larger calibers. This guide explores the world of 17 HMR AR magazines, covering various aspects crucial for informed purchasing decisions.
Understanding the Challenges of 17 HMR AR Magazines
Unlike larger calibers readily adapted to AR-15 platforms, the .17 HMR presents unique challenges for magazine design. The smaller cartridge dimensions require precise engineering to ensure reliable feeding and function. This leads to fewer manufacturers offering compatible magazines, and those available may have varying levels of reliability and performance.
Key Factors Affecting Magazine Performance:
- Feed Lip Design: The feed lips are critical. Poorly designed feed lips can lead to jams, misfeeds, and unreliable cycling. Look for magazines with robust, precisely engineered feed lips.
- Follower Design: The follower's design impacts how smoothly rounds are fed into the chamber. A poorly designed follower can contribute to malfunctions.
- Material Quality: High-quality materials are crucial for durability and longevity. Magazines made from cheap plastics are more prone to breakage and deformation.
- Spring Tension: The spring needs to provide consistent and sufficient force to feed rounds reliably without being excessively stiff. A weak spring will lead to feeding problems, while an overly strong spring can cause wear and tear on the magazine and firearm.
Types of 17 HMR AR Magazines Available
While options are limited compared to other calibers, several types of 17 HMR AR magazines exist, each with its own advantages and disadvantages:
Standard Capacity Magazines:
These are typically designed to hold a standard number of rounds, which varies depending on the manufacturer and specific magazine design. Capacity usually falls between 10 and 25 rounds.
Extended Capacity Magazines:
These are designed to hold a greater number of rounds than standard capacity magazines. They offer increased shooting capacity but might be slightly longer and potentially heavier.
Drum Magazines:
While less common for .17 HMR, some manufacturers may offer drum magazines for higher capacity. However, these are often more expensive and can be prone to malfunctions if not properly maintained.
Tips for Choosing the Right 17 HMR AR Magazine
- Read Reviews: Before buying, check online reviews from reputable sources and forums to gauge the performance and reliability of different magazines from various brands.
- Consider Capacity: Choose a capacity that suits your needs and intended use.
- Prioritize Quality: Invest in a high-quality magazine from a reputable manufacturer; this will likely save you money in the long run.
- Test Thoroughly: Once purchased, test your magazine thoroughly at the range under various conditions to ensure reliable performance.
Maintaining Your 17 HMR AR Magazines
Proper maintenance is vital to prolonging the life and reliability of your magazines. Regular cleaning to remove dirt, debris, and lubricant buildup is crucial. Avoid using harsh chemicals, and always store your magazines in a cool, dry place.
Conclusion: Finding the Perfect 17 HMR AR Magazine
Selecting the right 17 HMR AR magazine involves careful consideration of various factors, including design, material quality, and capacity. By understanding the nuances of magazine design and conducting thorough research, shooters can find a reliable and high-performing magazine to enhance their shooting experience with their .17 HMR AR-platform rifle. Remember to always prioritize safety and follow proper firearm handling practices.
