Shopper this product is compatible with the speargun JBL D6?
HARVEY H Can't say for sure because I am not familiar with your model. However if it is JBL and designed for 24 inch shaft then this is very likely to work as it's the most common type. Leisure Pro is also good with returns if it doesn't
MANUEL H No, the JBL D6 uses 9/32" diameter shaft. And the Magnum series use 5/16" diameter, the Magnum is built for more abuse.
JUSTIN R Not sure. I just grabbed it as a quick backup and only used it twice. Great gun out of the box, though.
