Finding the right magazine for your DPMS .308 rifle is crucial for reliable function and performance. Understanding magazine compatibility can save you frustration and ensure you're always ready when it counts. This guide delves into the specifics of DPMS .308 magazine compatibility, exploring various brands, capacities, and potential issues.
DPMS .308: Understanding the Platform
DPMS (formerly DPMS Panther Arms) produced a range of AR-10 pattern rifles chambered in .308 Winchester (7.62x51mm NATO). While they've since been acquired, their rifles remain popular, and understanding their magazine compatibility is vital for current owners. It's important to note that not all AR-10 platforms are created equal, and magazine compatibility can vary significantly between manufacturers.
Magazine Compatibility: The Good, the Bad, and the Ugly
DPMS .308 rifles are generally designed to work with magazines that follow the SR-25 pattern. However, "generally" doesn't always mean "universally." Here's a breakdown:
Magazines That Generally Work Well:
-
DPMS Magazines: These are the most reliable choice, offering the best fit and function. If you own a DPMS .308, investing in their proprietary magazines is often the safest bet. However, these magazines might be harder to find now than they were in the past.
-
Magpul SR-25 Magazines: Magpul has a strong reputation for producing high-quality magazines, and their SR-25 Gen 3 magazines are often compatible with DPMS rifles. These are a readily available and reliable option.
-
Lancer L5AWM Magazines: Lancer is known for its durable and reliable magazines, and their L5AWM magazines are often compatible with DPMS .308 rifles. These are a great option for those seeking robust performance and reliability.
Magazines That Might Work (With Caveats):
Some magazines from other manufacturers might work, but this is not guaranteed. You might encounter feeding issues, magazine wobble, or other problems. These issues often arise from slight variations in magazine dimensions and the rifle's magazine well. Test any non-DPMS magazine thoroughly before relying on it in a critical situation.
Magazines That Likely Won't Work:
Avoid using magazines designed for other AR-10 platforms (like Armalite or Bushmaster AR-10s) without extensive testing. These are unlikely to function correctly in a DPMS rifle due to differing magazine well dimensions. Using incompatible magazines can lead to malfunctions, potentially dangerous jams, or damage to the firearm.
Troubleshooting Magazine Issues
Even with compatible magazines, you might encounter problems. Here are some common issues and troubleshooting tips:
-
Feeding Problems: Try different magazines. Clean and lubricate the rifle and magazine. Check for any obstructions in the magazine well.
-
Magazine Wobble: This can indicate the magazine isn't fully seating. Ensure the magazine is properly inserted and the magazine release is functioning correctly.
-
Failure to Feed/Eject: Again, try different magazines. Examine the rounds for any damage or defects. Check the rifle's gas system.
The Importance of Testing
Before relying on any magazine for your DPMS .308, always test it thoroughly at the range. Fire a significant number of rounds to ensure reliable feeding, ejection, and overall performance. Never use a magazine that consistently malfunctions.
Conclusion
Choosing the right magazine for your DPMS .308 rifle is a critical aspect of responsible gun ownership. While DPMS and Magpul magazines are generally the safest bet, always perform rigorous testing with any magazine to ensure compatibility and reliable function. Safety should always be the top priority.
