My buddy just received a new FX 25 cal MK2 today fresh off the FedEX truck, with a serial number of 1919xx. We loaded up the magazine and immediately discovered a problem, it would not load a pellet. After close inspection we discovered the probe was sitting LOW and contacting the lower lip of the brass inlet. We removed the set screw holding in the probe and inspected it, it looks good. One note, it appears that FX has upgraded the square block that holds the probe with a bigger set screw (that's good!). We put the probe back in and tried again, no luck, it still would not cleanly load a pellet. Then we discovered if we held the gun upside down, it would cleanly load pellets every time! In other words, gravity alone fixed the problem. We took off the cheek piece and top rail and you can see in the video when the gun is upright, the probe hits the bottom of the brass inlet and is not centered to go into the barrel. If we cock the gun and jiggle the handle, we can get pellets to load, but it pretty much does not load a pellet cleanly, or jams. I'm not sure if anyone has encountered this problem, or has a suggested fix? It almost appears if I was to remove the square block that holds the probe and sanded off just a tad of material from the block, that might cure the problem by raising the probe just enough to center it? Of course I don't want to do that yet until someone lets me know if something else might be causing the problem. Or possibly FX has changed the square block and not machined it properly? The screw that holds the square block onto the sliding rail is tight, so i know that is not the problem. The bottom line, the darn probe is just sitting a little to low. Any suggestions very welcome.
