  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.

    This is what XTX says about the HuMa regg

    HuMa Regulators



    HuMa Regulators for the BSA Ultra SE & Scorpion SE


    HuMa who?

    The Huma regulators were developed by a couple of guys in the Netherlands, one is called Huub and and the other is called Marc, so the regulators have been called Hu(ub)Ma(rc) regulators. They have developed a number of interesting parts and regulators for a range of rifles.


    What is a regulator?

    A regulator is a device that regulates the pressure between the air cylinder/bottle and the firing valve. It allows air to to flow through to the action until it reaches a pre-set pressure and then it shuts off the air until a shot is fired, creating a constant pressure at the firing valve. When the rifle is fired this pressure drops then the regulator opens to allow the air to flow through to the firing valve again until it reaches the pre-set pressure. By fitting a regulator you eliminate the power curve and the hunt for the sweet spot that is common with most unregulated rifles.



    Where does the regulator get fitted?

    It is fitted in between the air reservoir/cylinder and the firing valve. The BSA SE Huma regulator allows the on board pressure gauge to read cylinder pressure unlike other regulators that only read the regulator pressure, so no guessing how much air you have left. The regulator has been designed to replicate/replace the existing valve body adaptor, this means that it does not need to be modified when fitting the regulator, so less chance of leaks etc. It also means that it is possible to put the rifle back to standard without having to replace a number of expensive parts.

    in a distant galaxy, far far away ....... actually
    we have no experience of these regulators, but darrin (xtx) fitted a tench one to our ultra and it awesome. i would think that darrin would have thoroughly tested these regulators, and would not fit them if they fell below his high standards. therefore, i would have no hesitation in purchasing if darrin recommends them

    I had asked exactly the same question on other forums a month or two ago but for a definitive answer decided to go to the main man so I have just spoke to Darrin.

    I am having my .177 Ultra Se regged and he said that the original tench reg one was mainly used for the previous Ultra model and recommended me having the HuMa fitted as it was designed for the Ultra Se and requires less modifications to the gun (hence cheaper and you can put it back to its original state) but they both work in a similar way.

    I said that the XTX site showed that it should achieve 40+ regged shots and he said that he aims for 50+ so no probs there then! The gun is then is set for 11.5ft/lbs and away you go, not one to wish my life away but roll on January when i get it back all HuMa reggged.:D

    Merry Xmas

    Cannot say anything about Tench regulator but graph shows actual result in my case, of adding HUMA reg, and just drilling transfer port, to a MMC Multi .177 Ultra.

    Graph shows 60 shots from 210 bar fill before (in blue) and after fitting. fps drops of quickly after these 60 shots both before and after reg fitting. It was necessary to reduce power, which I did quickly by reducing hammer spring tension. Before fitting Max power was 11.93 fpe. After fitting before adjusting Max power was 12.37 fpe. After adjusting (as in graph) Max power is 11.28 fpe. Standard deviation of fps reduced from about 15 to 6. Will see how consistent it remains before attempting any further adjustment (lighter hammer / hammer guide for example), but given that I was fairly happy with the rifle before I may just stick with this. Certainly the Huma reg works to improve consistency, and was easy to fit. I bought it from XTX but could not wait until the next available time slot to have it done by Darrin

    Both my guns have tench regulators and I can't fault them, I get 100+ shots out of both s400 and s200.

    I have a Tench reg in my Ultra, & a Huma reg in my Hornet. No problems with either reg & both guys are great to deal with. The Huma is a diy fit, not so with the Tench reg.
    I have noticed that the Huma doesnt like pressure above 200 bar whereas the Tench will cope with more, but not neccessary to go above 200 with either. I use Tench for my servicing because he is more local & I see him or his brother at local comps.

    I spoke to John Bowkett a week ago about regulating an Ultra or Scorpion and tentatively mentioned Huma regs. He said "they're very good" with no negatives mentioned. That, to me, means they ARE very good!

    Hi Guys,
    I fitted a Huma reg to my 2 year old FTP 900 as the AA was playing up. Very easy to fit if you follow Huma and Darrin's (XTX Air) instructions and you don't need to drill a hole in your cylinder so easy to go back to standard. I now get a spread of about 8 fps, good for me.

    Rob.

    My ultra se has one of Carl Garbetts regs fitted along with a full tune. Cant praise his work enough. Airtech is his company.

    I heard and saw some photos claiming them to be copies of Huma regs but lacking similar pressure testing. I have both Humas and Tench regs. Both work well for what they are designed to do.

    The Technical Officer, no less:D, for the B*A *wners *roup stripped one of Airtechs down that was giving problems and did a side by side comparison with a Huma reg. It was definitely a direct copy according to that fine fellow. Naughty boy.
