1. The Forum Rules have undergone some minor changes and updates.  Please take the time to read them; it will only take a couple of minutes of your time. By doing so, you lessen the chance of incurring the wrath of the moderation team or making yourself look foolish to other members.

    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.

    'Behaviour

    Do not make inappropriate or offensive posts - including threats, harassment, swearing, prejudice, defamation, deliberate insults or name-calling, other negative remarks about this forum, its moderators and administrators or your fellow members. Even if this is just your own personal opinion, RESPECT YOUR FELLOW MEMBERS.'

  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.

    Looks like my impact has the C3 bumper that's giving up. Went to shoot targets in the sun outside and thought I'll shoot over the chrony. See if a droo or rise from point of aim aligns with speed over chrony.
    Few test shots first to measure reg creep speed drop, about 20fps drop on first shot to average after.

    My speeds were way off some low then some high, over a ftlb difference. Looked at the hammer rod that should be sitting flush or just under flush as mine used to, now it's a little proud.

    Anyone making the impact kits available yet? If not where is the best place to buy a delrin bumper and a seal kit, I'm bound to tear one or two up during strip and rebuild.
    Many thanks for any help advice given.

    Replace it with a delrin one.
    I've got some spare. PM me your address and I'll stick a couple in an envelope.

    You don't need to strip to replace. It's a ten minute job :D

    It will be a better gun when you have done it.
    I can’t for the life of me understand why FX aren’t doing this as standard, it’s a well documented issue.

    My understanding is that the new ones are (hope it not just FAC versions) as the AGC received their first shipment this week we may see in the next week or so.
    One pallet of rifles yesterday on tomorrow more next week, a couple of weeks for all the spares and accessories

    I'm sure the latest batch are fitted with them. Mine oy being three months old, I thought would have been fitted with a delrin one.
    It probably only give around 2mm or so but it's enough to spoil the consistency.

    i think that could be the valve seat and may not be the c3 bumper is yours a FAC impact

    Part B27: FX Impact Valve Seat

    when the valve seat splits it allows the valve stem to move back and stick out a bit

    Jefsky mine is the sub12 model. I'll have to watch a few videos to check correct placement of the stem. A strip down to check it all.ight be in order.

    If the valve stem is in this position the seat is good, :thumb: if it sits out further the seat or valve is at fault the C3 bumper has no affect on the seating position of the valve stem.
    good luck :up:

    Right here's a couple of pics of it, can't see how much it sticks out but I'd say about the depth of the chamfer on the end. Seems a little worse after firing a few shots.

    I would say looking at the photo its the valve seat or the valve dose it have the larger mk2 plenum, you only have the updated valve seat if you do

    If you have the larger plenum then it won't be the seat could be the valve, i think your right a strip might be in order have a look what's going on

    Ha ha mice seems your not the only one with a poorly gun.
    I could return it as I haven't done anything to it yet. Not sure i want my gun being a guinea pig for SGC to play with. Or would it go to ASI.

    Decided I'd ring the place I bought it from, they're going to collect it next week.
    As it's got the reg creep issue I might as well let them sort it all out.
