Magazine notes

Uses M4 / STANAG AEG magazines. Current UK listing warns that some P-MAG/Hexmag-style polymer magazines may not fit; metal STANAG/S-Mag-style magazines are recommended.

A shared pattern or interface helps narrow your search; it does not guarantee fit across every brand or revision. Follow model-specific notes.
