Not for Gamo's. We do not offer springs for them as they are often used but not a practical Gamo spring. Users mostly do not have the skill to re-guide Gamos like any good tune requires. Its just beyond the scope of ability for a novice. Sure mostly any spring will work and these have been used by a Tuner of Gamo's and Chinese guns- people like them too. But to me unless other work is done you get what you get.

That said- others with skill have worked miracles on Gamo's.
