FX Panther Hunter Compact bottle filling issues

[Barzor]

I know there is a master class to convert Panthera to Hunter moving back bottle to front. But how do you add an extra bottle to back. There is a large black round piece on the stock. I am guessing this is removed and same adapter ST0057 you plug at back with 300cc bottle and valve. Is this correct. I am guessing when doing all this that all the air is removed from rifle including removing front bottle.

Then as it says in master class screw in both bottles in same time. But I am assuming both bottles are full I will need a adapter to fill just the bottles then.

Once both bottles are connected can you still fill from the rear butt stock spigot Will air fill back bottle first then front or will they be both filled same time I assume.

Finally let’s say both bottles on the rifle and gauge say time to fill. Is it ok to remove one bottle fill with air remove other bottle and fill then screw in together again. Will the air in plenum stay there?

im so confused when having 2 bottles and how to fill.

I hope someone can help.

Not intimately familiar with your setup but in MOST guns one shouldn't have to remove bottle to fill. Who'd want THAT hassle?

Yes using the rear fill port will fill both bottles

I bought my gun preconfigured with 2 bottles out of the box.
You need to buy the extra bottle kit, which comes with a bottle adapter and block off plug. The male fill quick connect is in the rear butt stock, by where the rear bottle screws in. In front bottle only configuration, the male fill quick screws in the bottom of the action block in front of the trigger. This gets blocked off with the plug in the double bottle kit. Both bottles are individually sealed with their own valves, but the plenum /system is open when bottles are removed, hence the need to screw both bottles on together (and off) at the same time. Both bottles fill at the same time from the single rear port.

Not sure if you have panther hunter compact but this rifle has the bottle at front I want to add a 300 at back. If I remove the front bottle for now can I remove the back plug or wil

Hi racer just to clarify this is the piece that you need for both ports, correct? Depending if you already have it at front or back this is all that’s needed pic with one adapter. Since I have the Panthera Hunter compact the port not used already has the circle plug such as the picture with two pieces. Sorry for the confusion just trying to buy the right parts.

@Barzor
Correct.
If your fill port is in the action, by the trigger, you need to move it to the rear butt stock on the right side below where the bottle attaches, and surmising moving the plug up to where the fill port previously resided.
