Weighted Scuba Barrel Insert | Disco Hybrid

Replace your barrel insert on your Disco Hybrid with a weighted variant so that your speargun can sink & go down with you. 
The standard disco hybrid is designed to float with the shaft out, which is optimal for freedivers but not so much for scuba divers. 
 
The standard barrel design that allows the Disco Hybrid to break down is entirely modular; this barrel will swap right in, no tools required.
