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.

    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.

    no, set the gun up as soon as you buy it...so buy one, strip it, rework it, then shoot it ;) however just adding a washer to a shrunken spring does help ;)

    Brand new LGU spring is around 238mm long, i just measured 5 ;)

    The springs are VERY good, the issue is the small port mainly and the lube they use. I like the lube (i have tubs upon tubs of it) i just do not use it on piston seals ;)

    Will the rifle continue to lose power over time or just settle at a lower level?

    I think it will level out and may need a washer or 2 to bring the power back up

    Well after putting another couple of hundred shots through my lgu it seems to of settled at around 11.4. it looks like the answer is to take the port out to 3.2 if your power has dropped
    Thanks for all the help

    If you lighten the piston down to 200g (60g off) you can take the port out more, and increase the efficiency more...if you go down to 170g or so even larger (0.177)

    on the .22's, do not go over 3.2mm port, 3mm should be enough even with a light weight piston.

    gents...they are ONLY guns and easy to sort out. I just tonight tested a brand new impact 100 I bought only to get it home and while refilling it the banjo on the reg blew out an O ring down to poor design. Its a sickener as i drove 240 miles just yesterday to pick this gun up. Am I annoyed yes, and I having a go on the forum...nope as its sortable.

    90% of the time the shops test them, if they are over (and many are) they just pack the pistons with grease to slow the piston and springs down..it also makes them shoot nicer (for many anyway)

    I suggest if you opened it, just clean it out saving the grease you remove so it can be reused....and set the gun up how you like it ;)

    Every gun i buy is just a kit of parts, they are never how i like em. If the bluing is mint and the stock unmarked then its a minty to me...the innards are easy to sort afterwards ;)
