Light pistons .

Fri Oct 09, 2015 8:07 am

Where to get a light weight piston for a TX 200 ???
What's the advantages of a lighter piston.
Can you make the original piston lighter.

Nick Gibney (I think Nick G on here) makes custom short stroke lightweight ally oring pistons specifically for the TX200, they absolutely transform the gun, about as close to a PCP as a springer can get. Virtually no sight picture movement (the cross hairs stay on the target and you can see the pellet path & strike) together with very consistent fps performance.
Lightening the standard piston in isolation, whilst possible, will not deliver any real benefit.

advantages of a light piston is in the shot cycle. working on engineering principals of every action has an equal and opposite reaction. less mass is moved therefore less recoil is produced. yes a std piston can be reduced in mass by turning it down on a lathe. where to get an alloy piston, contact Nick Gibney or Nick Murphy. when using a light piston you will need extrapreload on the mainspring as the power will be reduced with a lighter piston.

I've finally got my TX200HC bedded in now (about 2000 pellets) and now it has settled down I performed a chrono string last Sunday. I was surprised to record an 11fps spread over 20 shots, as this is exactly the same spread as I recorded with my SFS tuned HW95 immediately afterwards. :shock: 8-) Over the 20 shot string, my TX200HC did not break the 10fpe barrier once, only recording high 9fpe. I'm not hung up on the power thing, I am much more concerned with a sweet shooting, accurate rifle. However, I'm intrigued as to what Nick can offer to improve my rifle.
