Considerations & Trade-offs
- Designed for specific magazine families, so compatibility is limited to ARC 10-round, AICS 5/10-round, and Accurate Mag variants listed in the product data.
- Not compatible with other polymer magazines, which narrows its use if your current setup relies on polymer mags.
- Capacity gain is cartridge-dependent, so the increase is not fixed across all supported magazines.
- The fluted exterior adds grip for magazine changes, but it also changes the magazine’s profile compared with a standard extension.
