  3. Dear members,

    Our membership (like our country) consists of people from all walks of life; different in far more ways than can be listed here and each with a different view based on their experience of life - regardless of their colour, religion or cultural heritage. Every single person in the UK has been born of mixed race – we are a multi-coloured and multi-cultural country.

    As many of you are aware there are a handful of individuals amongst this membership that persist in making provocative, inflammatory, racist and otherwise offensive comments. This has been happening across the forum to a certain degree but is most especially prevalent in the Adult section.

    The moderation team has tried to stay on top of this, however unfortunately because of the ‘offensive’ nature of much of its content we don’t monitor the Adult section quite as much as perhaps we should. As a result much of this behaviour has gone unnoticed unless it has been reported to us. While the team always intended to take a "light touch" approach to the Adult section it would seem that some people aren’t quite adult enough to be left unmonitored after all.

    This behaviour is, and always has been against Forum Rules as well as the specific stipulations of the Adults forum and it will no longer be tolerated. We feel it's time to draw a line in the sand and as such from this point onward offenders will receive an immediate and permanent ban from the forum.

    In order for us to achieve our goal of restoring the forum to the friendly and tolerant place it once was, we ask that ALL members be mindful of the content they post and help us to stop unacceptable behaviour by using the 'Report' tool at the bottom of any offending post - the results of which can be seen only by Admin/Moderators.

    You should all receive a copy of this message by PM.

  5. Postings on Politics, Religion & Controversial Off-Topic Material

    The majority of users do not want to read about these subjects and people have left the forum as a result of it – this is after all an 'Airgun' Forum. It’s all very well to say they don’t have to read it if they don't want to, but as most of us use the ‘New Posts’ button there is no easy way to avoid it.

    All AGF staff members are in favour of people being able to discuss what they want, but we have to draw the line somewhere if it is upsetting other users. We don’t want to read about these topics either.

    IMPORTANT- The discussion of politics and religion is no longer allowed anywhere on the forum (including the Adult section).  The only exception is if it's airgun related - they must be put in the Airgun Related Politics section..

    We will not tolerate bullying or personal attacks, racism or any other offensive 'isms'. we will remove these topics from the forum, we will not give you an area where you can abuse each other. We will not hesitate to ban offenders.

    I'm going to reg my phox
    I'm looking to make it as good as it can be, it's already accurate but the spread with AA, jsb and daystate 8.4 grains is horrendous at times. We're talking a 50+ fps spread. Sad times

    Just wondering what experience anyone has had with the 3 I've chosen
    Huma, Rob Lane or altaros

    Having looked at fitting instructions for huma I'm confident I can fit it. Although the valve assembly in the phox seems solid. I removed the C-clip and couldn't dismantle any further so I might have to replace it with the buccaneer housing, spring and valve stem

    An email off someone at Rob Lane simply said don't bother with the altaros because in a few months I'd be "crying to her" but with no reasoning

    I used the RL reg in my Coyote, same gun, as you don't have to drill the cylinder for the vent, as the RL reg vent from the rear, worked very well, but I suspect it won't nessacerily cure but may help your fps variation.

    What do you expect if you're asking a manufacturer about the competition??. Saying that Rob Lane is a top bloke always willing to give help and advice and doesn't usually slag the opposition off, if you rang him I'm sure he'd tell you why he doesn't rate them. Lane regs are good if you follow the fitting instructions fully. Fitted a few but not to a Gamo though.

    I’ve had a Huma and RL. I’ve got a RL in my Ultra and it’s helped shot count, accuracy not much different as it was good anyway. They are all roughly the same. I’ve never had a problem with them, but I’ve never fitted one.

    I think that email was probably from his secretary/female friend, had replies from her before and I don't think she has much of a clue, RL I think is currently away for a couple of months.

    Are you talking this amount spread over the course of a full charge with minimal variation between shots, or does it vary this much from one shot to the next (or over a relatively short sample of say 5-10 shots)? If it's the latter it sounds like a significant issues somewhere and as such simply fitting a reg most likely won't fix the issue...

    Both Lane and Huma regs are good; Altaros have been a bit hit and miss in the past (avoid their un-vented "cigar regs") but I'm not sure about their current offerings for this model.

    The email said get there's or a huma but avoid the altaros. I'd rather give the money to an English company though

    The fps spread was over 40 shots from 200 bar, since then I've tightened up the hammer spring and small tests haven't shown such a wide spread but I'd rather be able to make use of a full 232 bar fill

    Iv got the Huma regulator in my Phox and its well worth it, simple to install and it makes it so much smoother and quieter.

    I've settled on a Lane regulator. Keep my money in an English company what what

    Now, it says it's set to 130bar and I assume this is because I asked for 11.5 ft-lbs
    There's a note saying if I lower the pressure to 85-90 I need to widen the transfer port. I'm just wondering if anyone has any advice on what I should be setting this up to.
    @siggy what did you set yours at and did you make any further adjustments? Stiffer hammer spring or widened port?

    What calibre is your Phox? my Coyote was .177 and RL recommended 85bar and the kit came with a drill to enlarge the transfer port, but after some testing, i made myself another transfer port with std aperture, but then I also have different hammer spring as I had an SSG device fitted.

    It's .177
    I'll test it at 130 and if I'm not happy I'll look at buying a wider transfer port rather than drill the current one

    Can you explain why a lower bar needs a bigger transfer? Also at lower bar he said to fit the outlet valve spacers. Not questioning if he's right, I'd just like to know why I'm doing it

    Its to do with air volume, the less pressure requires a bigger transfer port to retain the same amount of force in theory,
    Although did fit the valve spring shims, I am not convinced they are necessary.

    Did you specify the reg pressure? or was it RLs recommendation, I am not sure why as its essentially the same gun inside as the Coyote which had the reg set at 85bar.....maybe he has changed his mind.

    He didn't ask me for pressure but he did ask for desired output in ft-lb
    It could be down to the coyote having a wider transfer port as standard

    Makes sense and that's what I was leaning towards, less pressure air as a higher volume would be the same amount as high pressure low volume

    Would it be better to go for lower output as I imagine if the regs at 130 I would fall off the reg sooner.. although if it's lower pressure but using more air then it would be about the same... my head hurts

    130 bar!!! Bloody hell that's high, the Phox must have a right weird/inefficient transfer.
    My Lane is 105 for a .177 AA400, the .22s are 95.

    From what I remember the Coyote transfer port dia is 2.8mm and the advice was to take it out to 3.4mm is that bigger than the Phox?

    I'll measure it when I get home but from memory I can't see it being bigger than 2mm tbh

    Transfer port is 2mm
    What reg pressure would you recommend? I'm aiming at 11+ ft-lbs

    I would get back to RL and ask him why the reg is set so high, to me that nearly FAC pressure, obviously he has a reason, but without knowing all the Phox data I wouldn't want to recommend changing anything.

    Seems legit, I wound the hammer spring down a bit and just gave it a fill to 232 and fired 6 up the garden and the highest output was a shade over 11 ft-lbs
    The echo in the tank has gone and including the mandatory dry fires in the house, I'm down to 220 bar
    So tomorrow I'll try to test properly, maybe Saturday
    Thanks for your replies
