MAKO Spearguns Replacement Railgun Barrels

All of our speargun barrels are made from the finest American made aircraft grade aluminum shipped directly from San Diego, Ca. to our barrel factory in Mexico where the aluminum is extruded to exact tolerances and cut to size.

From there, the barrels are anodized black and then shipped to our shop in Virginia. Upon arrival, all the barrels are once again inspected and the water stoppers installed. The final step is installing the enclosed track on all of our enclosed track spearguns.

Built to exact specifications by our extruder in Pennsylvania, the enclosed tracks are installed by hand by us and cut to length.

We keep a sufficient supply of barrels on hand and now offer them as replacements and for the do it yourself speargun builders.

We offer barrels for both Replacement or Custom build applications.

  • Replacement Barrels will be drilled and water stoppers installed exactly to our specs for speargun you're replacing the barrel on.
  • When you order a Custom barrel, we'll contact you and discuss your needs before we ship it to you.

Shipment arrived quickly and well packed. Replacing the barrel went quite easy.  Just small modifications were needed to fit all parts together.

No flex February 17, 2016
Reviewer: Mark Kowalsky from Midland, ON Canada  
The enclosed track barrel is significantly stiffened by the profile that the track slots into. This is my second one of these, and I love how quiet the gun is on firing with the shaft in a polycarbonate track.
