The E3650 Ultra spring -new

 35 x .120"

ID- .515"

Can be spaced up to fit many guns and boost power.

Now Improved.


This spring and the R9 Tarantula are installed into many guns. Often airgunners will hear these are great for a gun and then complain they lost power. They replace a 44 coil mainspring etc. with these straight away like it should do the trick. That is exactly why we sell spacers at the bottom of this section.
