How Long Can You Leave Your AR-15 Magazines Loaded? The Definitive Answer
This video definitively answers how long AR-15 magazines can be loaded, demonstrating that magazines loaded for 17 years (since 2005) with 55-grain soft point ammunition still functioned reliably. While best practice dictates rotating duty ammunition, the test shows that long-term storage in magazines does not inherently degrade their feeding capability, provided they are stored properly. The speaker, Dave Timm from Guns and Tactics, emphasizes that while rotation is ideal, loaded magazines found in storage can likely still be used.
