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.

    Hi I just bought this rifle from a car-boot sale for £20.
    I think it's a BAM B4 Underlever .22.
    I haven't shot it yet but it looks and sounds ok.
    It's quite an old and cheap rifle but I'm hoping to do it up a bit and I have a few questions...

    The finish on the stock is horrible and flaking off, I was thinking of sanding it off and using some sort of protective wood stain, any tips?
    The barrel is a little rusty, not sure what to do about that, just hammerite it?
    It's missing the rear sight, should I get a new one or is it worth getting a scope?
    What I really want to improve is it performance but I'm not sure how, are their any parts I can replace or clean up to improve it?

    Regards,
    Frazer

    Once did a B3, that was rough...
    The metalwork, 1st step - a rub down with oily wirewool. See where this gets you then decide if you want to spray paint it or not. The woodwork - it's probably coated in thick lacquer. This is for a reason, Chinese guns (at least the older ones), had a tendency to have gapping cracks or faults within the wood. These gaps will have been filled with woodfiller, you can tell because they show up as a much lighter shade. I found the easiest way to remove the lacquer was by using a heatgun and paint scrapper. Finishing off with various grades of sandpaper.
    As regards improving performance....well that's a different matter. I failed! Therefore I've got nothing to add!!
    Good luck.

    With regards to woodwork I use a paint and varnish stripper most available is nitromorse just make sure your in a ventilated area keep it off your skin and and eyes it can be nasty stuff , we use industrial stuff at work key thing is get a good amount on using a paintbrush (as my old boss used to say if its wet its working :/ ) ha scrape of wet again and rub of with wire wool (sand after) then you could oil it or stain and re-laquer down to personal preference really

    Thanks for the replies. I've got a good idea how to refurb the stock and metal now.

    I've done a bit of research,
    I'm going to clean the barrel.
    Get a rear sight rather than a scope as I find them more practical on a low powered rifle.
    Maybe get a silencer as not to attract to much attention from neighbours, and it's loud.
    Use a pointed or domed light grain pellet, any suggestions? H&N Baracuda Greens look good but they're not cheap.

    I had a Simular project ,the rifle had no real value . It wasn't worth a re blue but was rusty and stock was in need of refurb.
    Re barrel and metalwork I used a cotton cloth and oil over a week or so and gently softened rust until IDE got off as much as would come off. Stubborn areas I used cereal box card with oil to rub it without effecting bluing or ooo grade wool very very lightly .
    once i was happy I de greased metalwork and wiped it with locative rust remedy along its action evenly and sparingly.
    It cured rust,turned it blue ish again and looked better than paint flaking over its use latter on .
    It actualy looked very good but a tad patches close up ,no rust returned and looked very original.

    stocks as said nitromores to remove coating 000 grade wire wool gently ,a decent stain and for that I did I used a gloss glass finish varnish with quality brush.

    Danish oil is a nice finish but can be time consuming ,true oil gives better gloss and can be used with danish between coats from gloss to satin look however you like.

    A nice internal spit n polish will work wonders .

    enjoy your project

    This is a Lion underleaver. It is the what the B4 turned into. As an illustration of bits it will do to show you what's what. It may improve performance.
    View attachment 99171

    Polish the inside of 1, the inside and outside of 2 and the outside of 3. the ends of the springs 4 need flattening if cut mid coil and then mirror polishing. Clean all the crud from the spring. Fit a polished washer either end of the spring when refitting. Lightly coat the spring with moly when fitting.
    Check the TP seal in the end of cylinder 1, these can split and you will lose power. The piston seal can also be well shot which sounds like it, as they shouldn't be that loud. So it's probably dieseling. These are cheap enough to replace. If you want a new spring, don't buy an Ox, it will shake it to bits.
    Get a sample pack of pellets to find the one that suits the barrel. It has nothing to do with price or even quality. My Arrow shoots one thing, my B2 another, my BSA S10 something else. It's a minefield.
    Good info on DB4 on UKCAF.
    Hope this helps.

    Got bored the other day,could not get out fishing stumbled across DB4 ready to go to skip so thought I`d have some fun. this took about 3 hrs including fullstrip clean lube paint etc etc total cost about £10.00. All accessories off flea bay chinese sites costing pennies or bits out of shed painted up. Still a Censored gun but learn`t a few lessons that will help on my proper toys. On a serious note don`t throw money at your BAM you won`t get it back in value or performance beware the non existent anti bear trap and be careful on the strip. Mine had so much preload that if I had`nt made up a press to take the retaining pin out it would have taken my face off. have fun and good luck.
