Most Helpful Positive Review 9mer Look!
Very clean and operable! Ready to order more when it’s on sale…
Most Helpful Negative Review confusing mk4/Ar15
Doesn’t work with just any AR15 lower. When it’s written as /Ar15 I assumed it works with other lowers but my PSA lower wouldn’t feed with this mag.

Functional.

by JD, Verified Owner from TX, United States Written on November 8, 2024
These mags are functional. They load easily, fit well, feed well, and drop freely upon mag change. If the feed ramps were metal I would give these 5 stars. I have not researched, but the feed ramps appear to be replaceable. They are pricey as well.
