I recently stripped down and rebuilt my old Gamo CF-16 from circa 1985. Everything got cleaned and polished, I fitted a custom TBT drop-in kit, replaced the main spring, piston seal, all other seals, put in an upgraded trigger, got some plastic parts (transfer cylinder, pop up breech) machined from brass, plus stripped the lacquered beech stock before redoing it with TruOil. I encountered and resolved a load of issues (with the help of some very helpful people on the forum) and massively enjoyed the whole process.

So, I'd like to have another go, buy a secondhand springer and try and restore & improve it.

So my question is what would be a good option?

I don't know myself what would make something a good or bad, so looking for opinions. I guess I'd like to work on something a bit more challenging where I can really see a difference from factory standard, both cosmetically and how the gun performs.

Cheers!
