Brian, have you looked at some of the trigger mods available from Charlie Da Tuna, aka Bob and admin/owner of this site?
OK, sorry to threadjack my own thread, but I am confused. Why is the word A R C H E R converted in the system to ^&$@ss? Is that code for the original word or something...?
I am almost sure the RS2 main spring is the same as the TF89. Reason is I have bought a RS2 spring that fit the TF89. But things and models change but think they should be the same. With that being said I had problems with spring breakage and the last I checked Air Rifle Headquaters has a replacement spring to match (might want to have them set it if you do order one). I have had no problems since buying the ARH spring. The ARH oversized small Apex piston seal will also fit but needs an adapter. Only place I had found was Target Tune India which I had recieved the screw but not the springs they had offered. Shipping from India is hit or miss in their postal service but part and shipping was about $6 not a big lost if you don't get it. Or you can probably make one. There is a lot of info on how to lube tune your new rifle on the GTA. LOL
Paul68 The seal is the Apex small over sized by 8 thou. I had bought a flat head tapered screw to match the the piston thread. Got a piece of 3/16" flat plate and countersunk it to sit the screw head flat then shaped the outer edge at a taper to match the seal inside opening. Like you have limited tools but have a bench grinder to shape the taper. It worked but ended up using the Target Tune India adapter. The spring was a ARH E9870 last checked was still in stock. Hope that helps

Paul, that would be great. I have an RS2 that I'm planning to give a tune-up in the near future.
