I keep falling behind with this question but I was hoping someone could list any vacuumed or dry barrel guns that can be bought off the shelf....

[EDIT] Unlike many of the others it does not use a rubber nozzle type vacuum cuff.
The rubber nozzle first appears on the Russian "Taimen" which dates from 2000. Before that gun the company made a "Scorpion" pneumatic gun which looked similar, but it was a wet barrel gun. In Russia car parts like engine valve oil seals get used for spearguns, so I expect that the idea came from there. Now must guns use a similar vacuum cuff or seal and at a quick glance they all look much the same, although the sizes vary to accommodate the spear and gun muzzle they are fitted to. The "Revolution" uses a set of sealing rings, one in the line slide and the other in the muzzle, somewhat like the "Mamba".Hey Pete,
Maybe it's the lack of coffee, but I can't figure out what you mean about the lack of "rubber nozzle cuff"?
Is that the Salvimar/Palengas type "oil seal"?
(Which, if my understanding of it is correct, is actually a Dima invention;-))

If you look through this http://apox.ru/forums/topic/7362-разборкасборка-ружья-рпс-3/?tab=comments#comment-54022 then you will see: "If there is a burning desire to go to the arrow f 8 mm, take the valve stem cap from the VAZ 2108": This is to convert a 9 mm RPS-3 to an 8 mm shaft.Yes, the design looks very much like an oil seal and I have spent a long time early on trying to identify it as a stock one without luck. Might be a Russian old standard. But I also heard a story that Dima specified the dimensions and a mold is somewhere in Ukraine...
Can we do stickies on this forum?I keep falling behind with this question but I was hoping someone could list any vacuumed or dry barrel guns that can be bought off the shelf....

I would say that "one size fit all" concept for cuff seal is more theoretical than real. I`v read few times on Italian forums that that seal was not very reliable with 6.5 mm shaft ("free shaft"?) - barrel become flooded , maybe because of poor centering of the shaft in Salvimar muzzle..? Similar situation might be with 7 mm "free shaft" too. Neither it can accept 8 mm shaft with tang, only "free shaft"... So that statement that the seal is for 6.5/7/7.5/8 mm shaft is relative.. I suppose that seal works good with 7 mm shaft with tang if the seal is regularly lubricated and the tang is modified as on image above in this thread.
LG changed the muzzle, I wrote about it here:New LG
No safety on the Manilu "Revolution” which could be a problem if in the event of an accident investigators come looking for one. For those who scoff at such things Jay Riffe a few years ago stated that were it not for the safety on his gun it would have cost him his business when a diver...forums.deeperblue.com
@tromic
Can you explain how you can load an LG muzzle submerged - without having first emptied the muzzle? I can't figure out how it is possible as the main seal in the muzzle seems to sit stationary in its groove (as opposed to the Seatec design which lets it move to a bigger part of the bore where it can expand and let trapped water squeeze out when inserting the shaft).
Here is the only pic I could find which shows the o-ring seat, but it is of an older LG muzzle so something might have changed:
And can you remind me of the Tombas? Do you need to empty the muzzle of water before inserting the spear?
This old type LG muzzle could not be loaded submerged, only the latest new one - LG BLACK HEAD from 2019., as Pete told you.
It was explained also in a video in my post #9, by Claudio Basili.
Recent Tomba700X neither could be loaded submerged.
I think it could be changed pretty easily, replacing O-ring 15 x 2.5 mm in Tomba muzzle with X-ring 14.8 x 2.62 mm and some additional adjustment.
I found that X-ring here: https://www.metricsealsinc.com/nbr-quad/4114b-366y-b-s-q-14-8-x-2-62 but I can not order it from Croatia...
It seems they do not send worldwide...
