There's only two things it can be on a bait caster. Manufactures either use a anti-reverse bearing or a anti-reverse paw. On your BPS reels, you can check your reel schematic online at BPS reel repair to see what you've got or you can send your reel back. If it's an old Garcia that has a paw you can order it from any reel repair website. Be careful sometime they make them can tricky to get apart and reassemble.
