Choosing the right magazine can significantly impact your shooting experience. For AR-15 platform users, the Magpul PMAG (Polymer Magazine) is a popular choice, but the differences between the Gen 2 and Gen 3 versions can be confusing. This detailed comparison will help you understand the key distinctions and determine which generation best suits your needs.
What are the Key Differences Between PMAG Gen 2 and Gen 3?
The main differences between PMAG Gen 2 and Gen 3 lie in their design features aimed at enhancing reliability and durability. While both offer robust polymer construction, the Gen 3 incorporates several improvements based on user feedback and Magpul's ongoing research and development.
Enhanced Reliability and Feeding: The Gen 3 Advantage
The most significant improvement in the PMAG Gen 3 is its enhanced reliability, especially in adverse conditions. This is primarily due to several key changes:
-
Improved Bolt Catch Compatibility: Gen 3 PMAGS feature a redesigned geometry around the bolt catch, making it less likely to interfere with the function of the bolt catch, leading to smoother operation. This is a crucial improvement reported by many users who experienced issues with Gen 2 magazines.
-
Reinforced Lip Design: The feed lips on the Gen 3 are stronger and more resilient, reducing the chance of damage from drops or impacts. This translates to greater reliability and a longer lifespan, especially under heavy use.
-
Improved Follower Design: The follower in the Gen 3 PMAG is also slightly modified for better cartridge feeding, minimizing malfunctions even with harsh handling or less-than-perfect ammunition.
Visual Differences: Spotting a Gen 2 from a Gen 3
While the internal improvements are substantial, there are some visual differences to help distinguish between the generations:
-
Ribbed Body: The Gen 3 PMAG features a more pronounced, textured rib on the body of the magazine, providing a more secure grip and better control, even when wearing gloves.
-
Textured Bottom: The base plate of the Gen 3 also sports a noticeably more aggressive texture, aiding in secure handling and preventing slippage.
-
Over-Travel Stop: The Gen 3 includes a built-in over-travel stop that limits the distance the follower can travel backward, preventing damage and further enhancing reliability.
Which Generation is Right for Me? PMAG Gen 2 vs Gen 3 – Choosing the Best Fit
The best PMAG generation for you depends on your priorities and budget.
-
PMAG Gen 2: The Gen 2 remains a perfectly functional magazine. If you're on a tighter budget or can find them at a significantly lower cost, they're still a reliable option. However, the improvements in the Gen 3 often make it worth the extra cost.
-
PMAG Gen 3: The Gen 3 is the clear winner in terms of reliability and durability. The enhanced features translate to smoother operation and reduced likelihood of malfunctions, especially under stressful conditions. The added cost is often justified by the enhanced performance.
Addressing Common User Questions
Here we address some frequently asked questions about PMAG Gen 2 and Gen 3:
Are PMAG Gen 3 magazines compatible with all AR-15 platforms?
While generally compatible, it's always best to check the specifications for your specific AR-15 model. Most AR-15s will accept both Gen 2 and Gen 3 PMAGS without issues. However, some modifications or tighter tolerances in certain receivers might cause minor compatibility problems.
Which PMAG generation is more durable?
The PMAG Gen 3 is generally considered more durable thanks to the reinforced feed lips and the overall improvements to the magazine body.
Do the different generations affect the rate of fire or accuracy?
The differences between Gen 2 and Gen 3 PMAGs are not likely to significantly affect your rate of fire or accuracy. The primary improvements are focused on reliability and longevity.
Are there any significant cost differences between the two generations?
Yes, generally the PMAG Gen 3 commands a slightly higher price than the Gen 2. However, the added performance justifies the cost for many shooters.
In conclusion, both PMAG Gen 2 and Gen 3 are reliable magazines. However, the Gen 3 represents a significant upgrade in terms of reliability, durability, and overall performance. For most users, the improved performance of the Gen 3 justifies the slightly higher cost. Ultimately, the choice depends on your specific needs and budget.
