Hi, saw this page the other day:

The cross section of the Mundail Carbon Elite, with the wings & rail reminded me of yours:
Do you like loading butts? Seems like a good idea - you need a decent loading pad with my railgun - but would it interfere with aiming along the side of the barrel?
BTW my railgun has a 90cm barrel (tube measured end to end, inc. the part inside the handle & muzzle) too & the standard spear it comes with is 6.6mm x
130cm i.e. barrel length + 40cm. SA railguns usually have the barb on the bottom. [BTW you can get spears from RA in the UK for around 14 pounds, with a holed drilled in the rear. They offer a universal-style for non-RA spearguns. Various lengths & diameters. I notice Portland Oceaneering offers spears from various makers. Oh...I forgot...you probably make your own!]
