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.

  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.

A400 Piston Cleaning

    Hi,

    As the title suggests does anybody have any suggestions for a relatively painless way to clean the piston assembly on a Beretta A400? Picture of the little b****r below, last thing I used was Action Blaster which did help a lot, but didn't get it "clean clean". Someone at a local RFD suggested Copper Solvent from the same manufacturer, but it's powerful stuff and I didn't want to potentially damage anything..

    Help appreciated! C8A323.png

    Ultrasonic cleaner if you can borrow one or buy one cheap off eBay....great for getting these spotless as well as other small items like removable chokes.

    I never thought of this. My wife has one for cleaning Jewellery.
    Well did have, as of now we share it. I use it for cleaning gun components :)

    The piston is pretty much self cleaning to be honest. The seal is metal like a car engine piston.

    I just wipe the worst off and pop back in. Never jammed or skipped a beat since new. Had it since they first came out. Such reliable semi autos.

    Must admit I had a lot of trouble with mine so I sold it and moved on.....lots of other very happy customers mind you so I was probably just unlucky.

    Both me and my shooting buddy have beretta semis for rough shooting.
    I look after mine like a baby. Stripped, cleaned and oiled. He never cleans his. Out in all weathers and loads of shells. It just keeps on going. They’ve both been totally reliable.

    I did see Ultrasonic cleaners as a possible option, but wasn't sure if I could just the ones, as mentioned, that people use for jewellery etc!? I saw a couple of videos of people using them for gun casings etc but they looked rather professional (and expensive). I must admit I've never had any issues with my semi auto, it just works, but the piston was perhaps the only bit that got really dirty and was the toughest to clean. Thanks for all the feedback/suggestions, appreciated!

    Hoppes #9 is your friend. The piston assembly is somewhat self cleaning.

    Did you use special cleaning solution or just water?

    I think I just used deionised water, but you can get special stuff for using to clean carburettors in ultrasonic cleaners. Like I say it’s a while since I had one but I was impressed at how well it worked for little effort. They do reckon the piston actually needs little in the way of cleaning, it’s gets sooted up but as long as you don’t get oil on it and keep it dry etc it should work fine. I’m a bit OCD though and just wanted it clean.
