Hey guys,

Drill a big hole    Need more info about the gun like make & model.

The gun is an AB Biller 48" professional, aluminum shaft.

I don't have that speargun model but did some research on the AB Biller and found it has "a unique sealplug prevents water seepage into the gun barrel and is guaranteed to withstand pressure to a 200' depth".  So you might want to check the sealplug to see if it need to be repaired or replaced.

You can follow this link to identify the sealplug:
