Modifed Neptonics Reef Mech


    I only built six mechs for my own guns, I stole the geometry from Under Sea with minor sear angle changes.
    I made my housings from 17/4 along with the trigger and sear. The inside roof of mine was sand blasted
    so I could lay in a thin layer of 3M 5200 the cure time was 48 hrs. This mech is still in my gun and has survived 20+ years. I did not share the mod with anyone but my dive mates would tell be how quite my
    high powered gun was.


    The other silenced trigger builders discovered the mod on their own.
    Tin- Man I really like your version alot for unheated housings.
    Cheers, Don

    I ran into a minor problem while installing my line release. The release lever operates fine as long as the trigger is pulled back and stays back until the release lever swings. But if for some reason the line were to not release quickly, and the trigger moved back slightly forward of its original position (which the spring causes it to do) then the interior point of the release will get hooked on the spring, or the little nub where the spring is attached. In this case, the release lever will not rotate.


    I think that this scenario is unlikely to happen in the real world, but it still bugs me. I plan to limit the trigger swing so that it can't rotate forward beyond the cocked position.


    Does this happen with an "un-modified" Reef mech?

    I don't think so. The problem occurs when the spring pulls the trigger forward, past the point where the trigger sits when the mech is cocked.


    I think I will just put a small pin through the mech like the picture below. That should keep the trigger from moving forward too far. I am curious to know if this is a problem on un-modified Reef mechs, though. It looks like it would be.

    Tin Man---adding the retaining pin behind the trigger looks like an nice simple solution
    WOW, that mech looks almost bullet proof
    Also looks like it would weigh a ton, but my guess is that weight is not a problem
    How tall is the mech case from the top down to where the trigger exits the bottom of the case?

    Here's a shot of what the internals were doing, and why they interfered with the operation of the line release lever. I inserted a 3/32" diameter pin through the mech at the location of the red dot in the previous photo. The mech now works great, and the trigger cannot move forward enough to interfere with the line release lever.

    It was a disaster LOL But it was one of the first steps on the road that brought me here today. I would've liked to skip that step though, would've been an extra $300 in my pocket not having trashed that Riffe C3X.


    Sorry for the derail Jeff, just reminiscing.
