So the first Royale 500 I had was regulated, was a laser, and I seem to remember being able to just unscrew the bottle with air in it, and the bottle would hold the air. I just removed the bottle on this second royale 500 that I have, and the air came rushing out slowly at first as I started to unscrew it, then quicker and quicker as I continued to unscrew it and ultimately the bottle just emptied.

This leads me to ask, is this second Royale that I have regulated like the first one was and why wasn't I able to remove the bottle without the air escaping? Can anyone confirm whether or not this Royale 500 is regulated from these pics or some other way? 

Any help greatly appreciated!

Is this shiny gold thing in the cylinder of the block the regulator?






 
I don't think that's the regulator, it's the valve seat. If there is a regulator, it's behind it. You need to take out that valve seat and look behind it. See Ernest's video on how to adjust an FX Bobcat/Royale regulator on you tube and that will be helpful. I'm in the same boat. I ordered a non regulated Royale 500 and I'm pretty sure the one I got is regulated, but need to check.

I see people here doing repair work and maintenance on their FX rifles without looking at the parts lists. I will try to link the parts list and drawing here to the Royal 400 &500. If it doesn't come through just go to FX's support page and scroll down to the correct file. Don't know if this will answer your question Cliff but it is good information for the future. Bill

Thank you for the diagram AirgunBill and thank you Chasdicapua for the link to the video. From those I was able to figure things out pretty good.

However, I got it all back together and it seems to be functioning flawlessly, but now when the action is closed if I shake the gun it sounds like there is something sliding back and forth in the action. If I pull the side lever back about half way, just to the point where it starts to hit resistance, whatever the piece is that is sliding stops and the noise is gone. I don't even have to fully cock the gun, just get the side lever back far enough for the slightest resistance and it stops.

I'm pretty sure it didn't do this before taking it apart, but I didn't take any of the side lever components apart. Anyone have any ideas? It sounds like what people describe when they do reviews of the Wildcat, a noise when shaking the gun from front to back only I don't remember the Royale ever doing this. As always, any help greatly appreciated as I continue on this journey to try to learn my gun.

All the best,
Cliff

That shinny gold thing is the regulator.

The sound that you hear when shaking the gun is the hammer and hammer spring moving about. The hammer and hammer spring on all Fx guns are not held in place but are free. Once you cock the gun then these are held by the sear and you will not hear any sound. Its a brilliant design. When fired, the hammer hits the valve like a sling shot and does not bounce on the valve like traditional hammers thus no air wastage.

Cliff you may have a faulty check valve in the bottle.They should not let the air drain out on removal. I have not removed the bottle on my 500,but follow these threads for when the day comes for the inevitable maintainence.Found this other thread along the same lines

P.S. Did you find a regulator in there?

"AirgunBill"I wonder if the Royal has been updated with the 'sling shot hammer' that Ted talks about in this video in regards to the Wildcat. Check it out and see what you think. Bill
He talks about it at the 3:15 min point in the video.

The hammer design has always been the same, the "sling shot" hammer Ted is referring to actually is a free floating hammer.
To put it another way, the hammer has no contact with the valve stem when the gun is not cocked.
That's why you can hear a ticking sound when you're shaking the gun, cock the gun and the sound disappears.

Bingo, had the same issue on my Boss. When I removed the bottle, the check valve released all air.
When it was empty, I pressed the check valve stem a couple of times, and now it works as it should.
Probably the check valve wasn't seated correctly. Also found out it works better to unscrew the bottle quite fast, so the air in the bottle will help closing the check valve.

B.t.w. hsnmz is right, the brass nozzle is part of the regulator. So it is definitely a regulated R500:)

Weatherby, Paulcat, you guys were both spot on. I was able to actually get the regulator out and inspect it and get everything reassembled in working order. It seemed to shoot just fine this morning.

I think I may have to call AOA about the check valve in the bottle. I took the bottle off the gun and tried to tap the top of the probe that is apparently part of the check valve that sticks up in the hole in the bottle. That didn't work so I ended up taking the entire valve out of the bottle and you were right it was stuck pretty good. After tapping it a few times it freed up and I thought I was good to go so I put it back together, gassed it up and tried to remove the bottle again. The air was STILL leaking out which was pretty discouraging so I took it all apart again and this time I took the entire check valve apart and here is a pic of what I found inside. I'm guessing there was an oring in there at one time and it seems like I'm going to have to call AOA for a replacement. I put it all back together again and the gun gassed up just fine and works perfectly, but I want to know that it is functioning 100% as it should so I'm going to take the necessary steps to replace the oring or entire check valve if necessary.

Also, I found a thread detailing how to remove the shroud or free it up so that you can slide it forward just a bit to allow enough room to remove the bottle without removing the barrel. I was pretty surprised at how easy this was and can now remove the bottle freely. Heating the shroud with a common propane torch did nothing to tarnish the finish and it came right off in less than a minute. There is a grub screw under the base of the shroud that can be accessed after removing the shaft part of the shroud and the whole thing went back together even easier than taking it apart.

I must say, getting to know the internal working components of the gun is quite liberating and I wish I had done this years ago. I was always nervous about something breaking and not knowing how to fix it and needing to send it away but I think those days are getting behind me. I feel much more confident handling the gun knowing exactly how everything fits together. Who knows, maybe it will make me a better shooter haha.

Thank you for the help everyone!!!!!
Cliff

Here it the piece that was inside the check valve housing when I took it apart.


Here is a pic of the new clearance I have between the bottle and the shroud to allow for easy removal of the bottle. I needed to move it forward about 1/2 inch and it is exactly the perfect distance to allow the bottle to fully unscrew and slide out of the stock. Initially there was only about a 1/16 to 1/8 of an inch.


Here is gratuitous pic of the gun haha
