This gun does not come rigged from the manufacturer. We can rig it for you at a small charge to cover the time it takes. We will also upgrade to high quality Rob Allen 2mm mono and crimps with a single wrap.

A muzzle bungee is not provided by the manufacturer of this gun, but we feel it’s an essential upgrade if you want to avoid stressing when rigging your gun in the water after a shot. The bungee allows you to quickly pop your shooting line on the line release ready for your next shot. Without a bungee this can be a very fiddly and annoying job – especially with gloves on.
