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...
