Hello All,
On the pellet probe there appears to be a grub screw which locks the probe outer into position once adjusted.
However on my rifle it appears to be missing (pic attached).
Can you please advise size so that I can source replacement ?
Thanks in advance,
Vard
what size allen key- metric or imperial?
Could be M3...or 4ba
Have a feeling that the old BA threads will have been superseded by now although RAW were still using 2BA for the bolt/probe adjustment grub 3-4 years ago
The screw is missing so I don't know the size. However , there are 2 others grubscrews that look to be similar either side of the probe.
Can you take one out other side and measure it
doh.... :-[ :-[
Having removed and measured the grub screw either side of the probe(seems to be M3 ??)the inner one is smaller.
I've ordered a selection of smaller metric grubscrews and hopefully
1.) it's metric
B.) I've ordered enough variety.

Probably imperial on a Raw
Yep, seems to be imperial. Around M2 size . An M2 grub will engage and seems very near actual size .
Without digging my Zeus out what's it likely to be?
Anywhere near the same size as the valve retaining bolt? If not, try emailing RAW.
8ba 3/32 not 100% I used m2.5 die and m2.5x2.5 originals very small and not good to get positive tightness

Nope smaller than the valve screw.
I've emailed RAW and had no response.
I was considering maybe in the future a HM1000x but they can swivel now .

Will consider doing this .Thanks

hi mate did you figure the size out? I've got one that could do with em replacing 👍

had a quick look couldn't find any 4/40unf but found 4/40 unc?
Update : I ended up tapping out to metric . All good . The only thing is you have to make sure that the grub length is short enough not to stop it going back into the outer .And is also clear of the other grub screws .
Note : the new type RAWs just use threadlock
yes I have the later type thread locked version.bit naff the hm probes.
