Seneca Drangonfly bolt probe O'ring

[Ultramarine]

My Artemis LR700w releases a short squeal at every shot. This doesn't seem to affect its power or accuracy but it's just unpleasant. I guess the bolt probe o'ring leaks but it's the only one I never changed on this rifle, as I should remove the barrel from the receiver, if I'm not wrong, and that's something I dare not do.
The Seneca Dragonfly being the same rifle (from SPA...), did anyone here ever change this o'ring ; or disassemble his rifle as far as this ? (should be parts n° 3 or 4 on the Dragonfly's exploded view).

Hello Yves good to see your still out there.  Sorry I cant help you with your question.

Hi Paulus, never mind.
Yep, still shooting as often as I can and still for fun. Sometimes I wonder if the LR700W doesn't squeal just to remind me that it's a more accurate rifle than all I could do. Yesterday I punched some paper once again -that's not what I love the most but there's no other  way to adjust my scope. The first 3 shots were too high and at right so I clicked a bit too much to correct this.

Well that is shooting straight for sure!

What range?

Thanks for your compliment
As for the range : 19 yards. 4x32 cheap scope, standing up and partially resting on the side of a garden cabin's door frame.
This riffle is accurate indeed. I spent some time (too much) fixing a valve leak, cleaning the bore and smoothing the trigger. It's almost as hard to pump as at the beginning. I usually pump 4 times for a 20 yards range and 6 times for a 32 one. Not pellet picky but definitely prefers Stoeger X-Field (a budget version of H&N Filed Target Trophy if I'm not wrong).
