Panthera FX Panthera/Dynamic Solid Bull Barrel Received

[Billm]

Billm,
Sorry to hear all the issues you have had with yours.
Hopefully I will see better results.
I placed an order for a 700mm 30 cal kit from EuropeAirguns and should receive mine this week.

Other than leaks my Panthera has been great, but I always find myself just seeing if I can pick up that last 1%.
Maybe this is it or maybe it is a waste of money. Only time will tell.
One thing I like is it removes at least 1 Oring from the "Tube Holder" anything that removes O-rings from this gun is a plus.
Additionally On another Panthera I had for a short while, I found the barrel tube had a seam in its construction that lead to a leak in the connection to the Tube Holder. I fixed that by sanding the exterior until the seam disappeared.

All these issues aside, I have had a multitude of airguns and my Crown and Panthera have the greatest mechanical accuracy of all the high end guns I have owned. Air leaks and all.

I can’t leave my airguns alone. I shoot some really nice groups and then I’m telling myself, “well, maybe it could be a little better”. I can’t help myself. Sometimes it works out and sometimes it doesn’t. I have no regrets whatsoever buying my Panthera MKII. I wanted to figure it out myself. But, when the FX guys told me not to risk damaging the plenum, as there are no spare ones available right now, I decided to let them install the Bull Barrel. Im guessing that you’re not in the USA.

I am the same way. Sometimes I wonder if I have it backwards, if it is not broke tinker with it until it is. LOL.
But I have also made some good improvements on my guns that way so I guess I will always tinker.

I am in the USA but initially I got notice from UA that they had the kit available.
I have bought from them many times as they get me parts quickly.
Actually quicker than I can get from FX US.
I got some parts for a Panthera, in less than a week that FX US told me 30 business days.

The only leaks I have had on ether of mine have been on the gauges an I used Teflon disks for there. The other spot is the Oring in the valve body and behind the valve stem when I turn the power up to achieve 250+ ft lbs which blows out that oring in the back of the body. To avoid this. I have fitted a washer to deflect the blast of air away from that oring at roughly 45 degrees towards the transfer port. No longer losing power when blown.

I only thought that because both Europe Airguns and Huma told me that they were not allowed to sell me FX barrels.

That the first I heard of it. I tried to buy their prototype solid barrel but they weren’t ready too. Pyramid is listing the 800mm so I was going to wait till they come out and get the .25.30and35

Hey Powermonger1,
Yeah the current leak I have I am pretty sure is in the plenum, one of the 14x2mm O-rings. But I am waiting for the kit to come in so I only tear down once. I probably nicked one when I did the change from 22 slug to 30 cal pellet. The last leak was inner O-ring for the Valve cap. Other than disassembling the front half the gun that one was relatively painless.

I have never bought a liner from Europe, but I have bought the sleeve as well as liner lock and all the parts to do a 700mm conversion.

I got complete Oring kits from eBay for $37 from captain Oring. Got extra kits for each of my FX dynamic too.
