    90% of users posting adverts in the Sales forums need to be reminded to read the rules as their posts are wrong.  This is unnecessarily time-consuming and will no longer happen - if your advert doesn't follow the Sales Rules it will be deleted and you'll have to start all over again.

  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.

    From that serial the rifle is an early one; dating from around 2001-2002. There are many, many small differences between these and later models; from my magical spreadsheet I can give you a few highlights of rifles the age of yours:


    - No anti-tamper; breech block held on with six screws from above, plain M3 transfer port adjuster grub screw and locking screw (the one you mention).

    - Uncoloured, embossed breech block inscription (model name etc) as opposed to the laser etching on later models.

    - Breech block is 2mm lower in height than later models.

    - Two-piece brass transfer port assy with no locking screw from underneath (current ones are one-piece, better and interchangeable).

    - White Nylon exhaust valve (far better than the newer, softer black ones) - DON'T CHANGE IT OR GET THE RIFLE SERVICED BY AIR ARMS. Don't fill with a pump as the moist air can kill the valve.

    - Exhaust valve pot retained by a plain M3 grub screw (later guns have an M4 screw and nylon buffer).

    - Flat faced inlet valve housing (inside the cylinder), around 5cc less reservoir capacity than later models. Exterior of housing has a 1/8BSP male fitting for the fill valve.

    - Standard hydraulic "snap connector" fill valve (newer guns have an AA-designed item with a different fitting to the housing).

    - No identification markings on air cylinder.

    - Two-sear trigger (the newer three-sear unit is much better and can be retro-fitted).

    - Plain trigger blade with no safety or return spring (the new ones with the safety are Censored).

    - Stock will have diamond chequering, if it's beech it's probably made by CZ (look on the buttpad) and is skinnier and more pale in colour than later ones. If it's walnut it's probably a Minelli (I think) item - will say "BMR" on the buttpad.


    Not the best vintage but fitted with a better exhaust valve and lacking anti-tamper so preferable to current models IMO, even if they are a bit more plain looking. The trigger upgrade costs around £70, is a bolt on swap and well worth doing IMO. I also changed the inlet valve assy on my S410 of similar age (serial is 030456) to the later (intermediate) style, as I didn't want to scratch the moderator with the female fill adaptor when filling. Your rifle should be pretty bullet-proof and well worth looking after :up:

    No problem - if yours has rosewood bits on the stock it sounds like it's been fitted with later woodwork ;)

    Nice rifle. Mine also starts with 02 and I believe the serial numbers generally start with the year of manufacture. Agree with the above in that that looks like later woodwork. Great rifles. Love mine. So easy to work on. Get yourslef across to AAOC. All the stripdown guides and advice you could possibly need, as well as supplier of discounted parts (bgaldt).

    Good stuff - looks like it's in nice nick, which is saying something considering that most S400s of this age tend to look shafted in my experience :rolleyes:

    That's definitely a later stock and would have originally have been fitted to a rifle of serial 060xxx - 100xxx or threreabouts.

    There's no strict correlation between serial number and year of manufacture, but it works as a rough guide. For example one of my rifles is 030xxx, yet was bought in June '02. Similarly current 400 series guns are on a serial of around 135xxx, but it's not 2013 any more ;)

    No problem - sounds like the rifle is going well :cool:

    I do love the 400 series guns and don't see any reason why they shouldn't go on forever if well maintained - which can be done yourself for very little money with a bit of knowledge, a few tools and a little care :)

    For the record the original stock on yours would have looked like this (but probably not lef-handed :p):

    Fair play for your determiniation - you are aware that you can get the rifles in full left-handed format though..? They're harder to come by but often cheaper than RH examples due to the limited market. Alternatively you could source a LH stock for this one and swap the bolt orientation to LH (I can tell you how, or there's plenty of info on the 'net).

    Ordinarily I'm not a big fan of swaping stocks about (I like to keep things original if I can) however since yours is alreadly missing the original stock it wouldn't be the end of the world IMO :)
