Custom Air Seals Short Stroke Piston Seal Feedback

[oldskoolzzz]

On my 95 thread I’m considering a Custom Air Seals short stroke piston seal (26mm) 10mm Short Stroke.

I’ve tried a search but can’t really find any feedback on them

Has anyone tried one and if so what’s your thoughts, feedback etc.

My only other short stroke experience is using the Tinners (TBT) nose but as I’m more than likely wanting to replace my seal as well I’m thinking the CAS route will kill two birds so to speak.

I have one in a HW98. Fitted it the same time as a tbt extension / kit in another. The custom seal took a little time to settle/wear in but has been fine since. Hard to tell the difference now.

Thanks for the reply

Would you say it maybe needed resizing a tad?

I’m assuming that’s what you mean perhaps a tad too tight at the start until it worn in.

Was there much power difference from when you first fitted it to what it is now?

The resistance when placing the piston in the cylinder wasn’t too bad. Only marginally more than the standard HW seal. I didn’t think it warrant resizing at the time. Power was lower initially before creeping up and settling around 11 fpe with low spread. Bear in mind it was a new rifle, new spring and drop in kit. Guess the whole internals were bedding in. I can’t tell the difference between the two rifles now, both shoot nicely with a shorter lock time.

Sounds good buddy thanks for the info

What’s the bore and stroke of a 95 and is this a ballpark SS amount for a 95 tune

26 x 86 IITC ? losing 10mm is a good place to be. HW99 that everyone likes at 11 fp is 72mm stroke IIRC.

So the sweet spot for a sub 12 26mm bore rifle is defo just around or a bit more that 72mm stroke. I think a 95 at 74-76mm is perfect.
