...have no doubt they're good and lovingly crafted but the action is all you hear on my Tweaky10 albeit there's a distinct boing of hammer spring resonance but it doesn't seem to spook the bunnies (thankfully)
In comparison I also have an AWT FAC spec mod on my SBSD Rapid and there you don't even hear the action
The T10 has an HW mod which cost £25 off here, the AWT cost £70 new (it was a while ago ).
The price mentioned above is just silly
