Fixing a sticky Mako trigger - how to
If your Mako exhibits any of the following symptoms, this procedure may fix the problem:
I have found the trigger mechanism on the Mako Predator Pro rail gun to be susceptible to becoming “sticky” if any foreign materials get in the way of the trigger return. There is a very close clearance between the trigger and its guide, and if sand or other gunk gets in the way, the trigger will not “snap back” to a normal position when a spear is loaded. Tools you will need:
Procedure: Remove the rail from the gun by removing the two phillips screws just forward of the handle. This will make things much easier to work on. Next, disassemble the trigger mechanism by first removing the single pin that holds the loading butt in place. Rest the handle on a wood block to steady it. Next, remove the safety by prying off the “S” button, and then pushing the safety through to the other side. (It removes from the “F” side): Next, gently pry the trigger cartridge up from the front of the handle assembly. Tapping with the hammer and wood block can “unstick” it without damage. Remove it by sliding it up and back out of the handle assembly. THE IMPORTANT STEP: Clean out the handle assembly with hot water, removing any traces of salt crystals, sand, or other foreign material. Pay special attention to the area where the trigger moves back and forth – clean the track with a Q-tip. Visually inspect for burrs or casting seams – remove with fine sand paper or jeweler's file if necessary (optional) The final step is to gently sand the areas of the trigger molding that contact the tracks on the inside of the handle assembly. Use 200 grit to bevel the edges, and then the finer paper to smooth and polish the surface. This shot is before polishing: Once the trigger is polished, test fit the cartridge back into the handle assembly. The trigger should pull and spring back crisply. Also test load a spear shaft to see that the trigger “bounces back” when the shaft clicks into place. Reassembly is the reverse of disassembly. Make sure trigger is not in “cocked” position before inserting it back into the handle. Hope this helps others! -Brent |

Excellent post!
Cleaning the trigger mech is something that needs to be done every so often. |

A hammer should be first on the list in everyone's speargun field-repair kit!

In fact, I'd say quite the opposite; the close tolerances in most finely machined equipment really benefit from scrupulous maintenance in order to keep them in perfect form. A sloppily-made piece of equipment with lots of loose play and crude machining will typically tolerate foreign materials and require less maintenance. In my opinion one hallmark of quality is the ease with which something can be broken down, serviced, and then reassembled without damage. |

I love it. The 'ol AK-47 vs FN-LAR philosophies This'll be great to bring up again in January!
