mag review

by Big-Jay, Verified Owner from NC, United States Written on March 6, 2026
These are great mags I already owned 4 of them , I bought a new 43x and I needed more , but you guys at the time where the only company with the S15 so its a good thing because Optics Planet is a very top-notch out fit. �

shield arms

by savedevin, Verified Owner from MI, United States Written on February 18, 2025
Love these magazines. They fit very well, just make sure you also purchase the shields arms magazines catch to go with it so you don’t run into issues like the metal magazine wearing down your stock polymer mag catch.
