Magazine notes

Uses the dedicated WE Apache / SMG-5 GBB magazine family. Current WE/UK listings include 30-round, 45-round and drum magazines; the magazine follower/lever provides stop-firing-on-empty functionality.

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