Frequently Asked Questions

Why might a shooter prefer USGI magazines over Magpul PMAGs?

A shooter might prefer USGI magazines due to their consistent drop-free performance, universal compatibility across various firearm platforms like the HK416 and SA80, lower weight, and often lower cost compared to PMAGs.

What are the potential issues with using PMAGs in an FN SCAR rifle?

Using certain PMAGs in an FN SCAR can cause the bolt catch to slightly rise and drag on the bolt lugs. This interference can lead to significant, potentially irreparable damage to the rifle's internal components over time if not addressed.

Are PMAGs compatible with all rifle platforms?

No, PMAGs can have fitment issues with specific platforms such as the HK416, M27 IAR, British SA80/L85, and FN FS2000 due to their unique body geometry. USGI magazines are generally considered a more universal standard.

How do PMAGs and USGI magazines compare in weight and cost?

PMAGs are heavier, with a PMAG 30 Gen M3 weighing around 148g, while a USGI aluminum magazine weighs approximately 112g. Additionally, new USGI contract magazines are typically $4-$5 cheaper than Gen 3 PMAGs.
