High quality carbon fiber barrels from Italy. 26mm inner diameter, 30cm outer diameter. Perfect track line up with the Sigalsub Nemesis and Ermes Avatar handles. I’ve found 90cm to be the ideal length for a reef gun. It tracks quickly and offers lots of power with laser accuracy; especially when paired with a Manny Sub single roller muzzle. Polyurethane foam filling available for an additional $15 upon request.
