Leshiy 2 explodes

Wooh - that's really scary. Any more details on the scenario and what happened? Was this in storage or while being used? Fill pressure at the time of failure?

Wow! I thought PCP tanks were designed not to fail catastrophically. More information please…

My first idea was that by the looks of the filter, there was a substantial amount of water in that tank. Then I look at the inside of the tube and see the anodizing is tact and no signs of corrosion. Did someone overfill it maybe?

He says he was shooting it when it blew up. Also says he filled to 200bar, went on to mention there was no prior visible damage to the tube. Maybe I will start wearing my full face motorcycle helmet when I shoot my L2 from now on. Keep in mind this was posted on Facebook, lots of fake stuff there, but it seems real.

One failure in the thousands of Leishys sold probably doesn't warrant a helmet, but airguns are supposed to have a safety margin built in so this stuff never happens so it's still concerning.

These examples are good reminders of dangers related to HPA operation, however, wouldn't condemn any airgun platform based on this. Don't know if airgun was dropped by owner, or by another, without owner's knowledge, which left no visible damage. If L2s exploded on a regular basis, yeah, then I'd agree to sound the alarm. WM

If that happened while he was shooting, the damage to his head, neck and probably arm would be substantial. Not to mention hearing loss. Was there any mention of injuries involved with this incident?

I believe there is cause for concern here as I would never want that to happen right next to what remains of my aging brain. But, I also have a few questions about what I am seeing in the picture. 2 specific areas circled below:
First one is the regulator nut. There is definitely what appears to be some damage there and that wouldn't happen on an outward explosion of the cylinder.
Second is the threading on the burst cylinder. While the tears in the metal do appear consistent on both sides I don't understand how they could be bent inward rather than outward.

Also, if that oring, in that position WAS being used, it would allow the threaded area to become part of the pressure vessel. It is not designed to have the pressure in the threaded area.

I mean, if the gun was improperly assembled after being worked on, that could cause this and at that point you should care?
Not saying that's what happened here as we don't know.

After looking closer, it looks like one side was cut with a cutting disc, the jagged side looks appropriate. Those tubes dont have a seam.

I noticed that as well, but don't want to make a judgement call on that. If it was assembled that way it would help explain the failure. Until otherwise shown, I would assume it was in the exposed Al slot in the appropriate place and was pushed forward during failure.
The more I think about it, the more you could be right though. The o-ring seems to be in perfect condition and perfectly placed.

I can't say for sure, but it's certainly out of position now. Perhaps it moved as the failure occurred, or perhaps it was an error in setting up the photograph.
There's a lot wrong in those images, and some of it (apparent corrosion) could have contributed to the failure. But perhaps it was the damage done to the threads that set up the initial crack in the tube. Hard to say without more input, either photos or statements from the owner.

I would like to see the other side of those pieces. The side resting on the table. I would bet there are signs of physical damage done prior to the final failure.
Rule #1 of high pressure components. If they look questionable, REPLACE THEM!

Airguns that have bottles / air tanks for a buttstock right where you rest your cheek do make me a little nervous. I would rather keep any potential failure away from my face.
