Good morning,

Could someone please tell me the exacts specifications of the TX200 Mk1/2 spring. My Google search yielded the following:

- 3.25 mm wire
- between 210 and 225 mm free length.

I am missing the number of active coils.

Background of my question, I am looking for a spring for a TX200 Mk1 in .22 and I am wondering if a (shortened) Maccari Hornet spring (38 x .125" wire- ID- .543") might be a suitable replacement. The OD of the Maccari spring fits the piston very loosely, wonder if that could cause twang?

Stroke, TP and seal are standard.


Best,
Jonas
