Short stroke drop in piston for the TX mk3?

[evert]

Thanks to all of you!

Seems like you agree on the stoke at about 77mm, but 180 or 252 grams, thats quite a difference!

What kind of springs are you guys using?

The FAC spring that came with the gun seems a bit stiffer than the sub 12fpe springs I have seen in a prosport a guy I know came with.

I'm thinking to go with a softer thinner wire spring, something dimensionally close to the old meteor springs, does that sound sensible?

Depends on the port... for stock port I'd go lighter end (200-220g max)

Yep, stock port. Thats what I meant with drop in, to keep the gun unaltered exept for a new piston.

I treated myself to a TX at Christmas, it had a Tinbum kit fitted & was very sweet to shoot.
I shall be using the gun for HFT & having read about Nickg's kit (it was the words "very little sight picture movement") that made me keen to try one out.
I fitted the kit last night & first impressions were, bloody hell thats quick. Power is at 10.9 ish with just one of the spacer/washers fitted.
Off to the club with it tomorrow for a proper session but early indications are that this is the springer that I have been looking for. Many thanks Nick

So this is one of those lightweight pistons, with an unaltered transferport?

Can I ask what spring you are using?

Yes, lightweight piston, standard t/p, the spring that comes with the kit.

Hi Nick,

Hope you're okay.

Yes, I've had the pleasure of a number of Nick's lovely creations at the Bash events and they're really something else. As you say, quick, not harsh and very little sight picture disturbance on many of his various tunes.

Hope you have a good session with it tomorrow. I will get there a few occasions this year, promise.

One of my customers lives in Waddington. He owns an Air Arms S400/410/510 (can't quite remember which) and a Brummy Stingray. Every time I see him I keep telling him that he really needs to get himself there. He's only a few minutes down the road (I wish I lived that close) When I last saw him on Thursday, it sounded like he's getting ever closer to making his maiden visit and I've asked him to come and find your good self and Mark for a friendly introduction.

All good thanks Tony.
Look forward to seeing you sometime this year.The club keeps picking up the odd new member here & there so will be pleased to see your custmer from Waddo.
Update from TX later this afternoon

Wind put paid to anything too meaningful this afternoon but I could see my pellet in flight miss the 45 yarders
