Operation TX

[Shed tuner]

Perfect... that's the thing with tuning a TX; they are such a good base, just sorting the seal and the stroke makes a gun gun excellent.

Not that you are likely to be short of ideas, but in keeping with the no machining / moderate costs, I'd also consider

- Roller thrust rear needle bearings (about £2.50 of the 8ay), make cocking smoother
- beer can piston sleeve
- new tight fitting Custom guides (cheating on the no machining, I know, but if they are available "off the shelf"....)
- LGU seal - they seem quite a bit more efficient in most guns that the HWs
- centre floating guide

I would say consider gluing a sleeve into the port, but it doesn't look like you have any slam, and if you are considering lightening the piston, taking the port down may introduce some bounce with tighter port... unless you want to shoot FAPs (I would !), in fact I'm not even sure I'd lighten it at all...
