I recently bought a 124 in very good condition. I fitted a new seal and kept the original (4’’ of preload) spring, and now it does 11.7ftlbs and is extremely accurate.

FWB designed these with a long, weak spring for good power with a very easy cocking effort. They shoot really well and I’m of the opinion they should be shot as they were originally designed to be shot, and not tuned with after market kits. (My modern springers are tuned though)

But that’s just me!

Enjoy,

Chambers list an "original" spring and seal - I presume this means they comply with the original spec?

I like the idea of the original spec, and am glad to hear assurances that it is not likely to be excessively harsh
