Very few available............no more after these.
Fits many Chinese-Spanish-Turkish Break barrels and guns who use a tightly wound spring. Like B series, Cometa 400- RWS 94 Etc-Winchester 1000.
.480" + ID, 39 coils x .120" wire- 13" OAL.
These are from a UK gunshop I purchased about five years ago. They fit like the E9870 spring we made
These are Chrome Silicon but made in the UK
It is best to order these preset as they are very long and typical of an original spring in unset length.
Meaning, hard to install and only a expert air- gunsmith should try!
