    Hammer spring logun mk2

    Hi guys.

    Have recently purchased an fac rated logun mk2.

    It's a really well built gun and in lovely condition, however I knew it wasn't shooting at the 30 ftlbs claimed by the rfd, as soon as I fired it.

    Checking over a chrono it was a feeble 8ftlb. The hammer spring has for some reason been ground down ( on the edge of a brick wall by the looks of it. ) A large brass washer pushed it up to 22.8ftlbs which is something I would be happy to live with, as running a pest control company means that accuracy is and shot count are equally important.

    However, when I then tried to zero the gun in it was very poor grouping with RWS Superdomes. I shall be getting the crowd checked but wont to replace the poorly cut down spring.

    Have looked at the usual supply companies and no one supplies the logun hammer spring anymore.

    Would anyone know of a suitable replacement spring ( i thinking FX perhaps) that would fit? And is it a standard spring with packing?

    Many thanks for any help...

    Logun pro mk2

    Most Logun's are set for accupells, I mad the mistake of using another brand and jammed it up, the pellet slide was shaving the skirt of the pellets. I also got poor groups due to this.

    As already mentioned give the airgun Doctor a ring. I'd of thought he would be able to sort it and sort it so it shoots different pellets better

    It's not that easy to change between pellets on the Logun professional rifles, the mechanism is set on pellet length, try a different pellet length and it either damages the pellet so that you get poor groups or jams the mechanism so you end up stripping the loading mechanism.

    Great guns but not one to tinker with 😐

    Regards Steve

    I really like it but for one thing. When it fires last pellet and you pull bolt back, it locks open. That's a good thing to stop you blowing air at them but I can't get it into the box I use for my van when moving guns around.

    Also takes up room in cabinet. I suppose I could just fire 1 pellet and not cock it...
