  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.

    All in one neat package, No wires, this is how it looks, fitted to my S200 multi shot .22

    55mm Fujinon prime f1.8 SLR Lens
    5" 800 X 400 Monitor
    1800 UK sourced battery, 4+ hours
    KT&C EJ 230 Bullet Camera with OSD.
    "Some Bloke" produced the housings
    501b Torch with ir pill
    Ball park figure £210

    Used to great effect on Rats in total darkness last night for the first field trial.
    Terry 1001 provided the drop in ir pill for an existing 501 b Torch.
    Exceptional quality of image, I was able to read the text on the feed bags at 20yds !!
    despite a lot of trial and a few errors, its not perfect for me yet, but its deadly effective out to 25yds with its currrent lens.

    Nice going mate, used the design from Dave to do mine just can't run to the box yet. They make a brilliant set up. What mag do you think you get from your size of lens.
    Taken 8 rabbits out to 30yrds and two rats at 5yrds showing the flexibility of this type of set up. What dimensions is your screen, I'm guessing it's an LCD.

    Looks very neat, how do you find it for day use? You never really finish projects like this, there's always another little mod to be done!

    Hi Terry I used mine in the day to bag a rat, and although you can tell the filter has been removed it's still surprisingly clear. Tend to alter the F rating and it sharpens things up. If you want this set up probably could replace your scope.

    I would guess around 4 x, i would like to try an 82mm or 100mm, but then there is the weight, and cost, particulally a "fast" aperture of at least F1.8
    at 10-15 yards, (some parts of my perm) the quality is stunning, I often watch the rats instead of squeezing the trigger!!!

    Screen dimensions are quoted as: Size: 12.5cm x 8cm x 1.2cm - via the slow boat

    Day time is suprisingly good, the colour is washed out due to the filter being removed, But I find adjusting the contrast and colour on the screen really makes a difference, something I'll try next time out at night.
    If spotting with it out of focus, the eye shine becomes very obvious, its simply brilliant.
    Your drop in pill for the 501 works perfectly, no washing out at all , Many thanks for that one.:up:

    Pleased the drop in does the job for you. You could try setting the camera to black and white instead of auto, it does help if it starts to switch between modes in very low light. When setting up a scopeless I tend to focus it in the dark, with ir, at the range I want to shoot - the focussing in daylight is quite a bit different but stopping down the lens to f8 or f11 gives a better image from the camera and increases the depth of field so that everything should be nice and sharp.
    I always find it amazing that these cameras are so sensitive, quite often you only need ir to see eyeshine as the image is bright and clear enough for shooting.

    That's the great thing about this forum, the sharing of information so projects can develope into what we all enjoy today.
    I'll try stopping down the lens in daylight, I hadn't considered that, although I did try to get a greater depth of field in darkness, which didn't happen. The sharpness though is top quality, did I already say that !

    Glad to see you like it SF, and to see some pictures too. :up:

    I don't see a switch, did you use one - and what battery type and fiitting did you go with?

    EDIT: That's an interesting barrel mount - it's compulsory to divulge more about nifty little gadgets like that. :D

    Looks like a scope mount they use on Crossman's like the rabbit stopper. The breach isn't flat to mount a scope on them unless you convert it so these mounts are used.

    If you look for Crossman intermounts you should be able to find them ( they are advertised on past times gun and tackle). To be honest they are crap for scopes as getting them to line up is a pain, so people usually upgrade the breech to a dove tail. Hope this helps.

    Dave,
    Tried the twin 18650 set up, but I suspect my cheepy cells we to blame for the low run time, about 90minutes.
    Got hold of a 1800 mAh and used the quick fit connector to wire in, hence No switch for the lash up field trial. Needed to make a little more room for this battery, but well worth it for the vastly improved running time. A tidy up with the wiring and I can reinstall the switch.

    I didnt consider the mounting of the Scopeless untill I had built it, On the S200 it was a little too close to my eye, so I adjusted the forward sliding mount on the barrel until I got a better position and used that one (see photo). Clamped in place with the grub screws, so far its solid, and only requires minor adjustment of the Cross hairs. (A bit of good luck for a change)
    So Now A Question...
    looking at the mount position on the S200, any suggestions as to what arrangement might allow two mounting rings to be useable, and still provide the same distance from the eye? (before I consider changing the rifle!)

    SF

    Can you not fit a pair of those mounts side by side, it looks as though there is enough space. If it's a little too tight you could trim a touch of the side of one of the assemblies.
    Mounting a scopeless unit is usually the hardest part but having it built into a 30mm tube does make it much easier - until you want to mount it firther forward on the rifle than the ordinary dovetails allow. You could try the cantilevered mounts although they wont give much extra, my way would be to fit a long picatinny rail using the existing dovetails on the rifle plus a pair of risers but this would require some fettling depending on the actual parts you get and it may make inserting the magazine awkward on some rifles. This is a fairly simple job on a milling machine but could be done by hand with plenty of care and it does give you the option of making some slight adjustments to the alignment by packing the rail as required.

    Blimey, I hadn't noticed there is little rail in front of the magazine TBH.

    Like Terry says then - a pair would be a more solid fit that is less likely to shift, but how solid is the barrel mounted?

    Looks a great set up lads, I'm sure we'll soon be seeing a lot more being built especially if you can keep listing the parts used as Silverfox has done on this one :up:

    What ranges can you expect to get from one of these, are they going to be suitable for rimfire?

    hello, having seen and looked through andys n/v set up on my farm perm i can tell you i was surprised how good this was and he has taken great care to do this n/v using the parts as descibed, even more clear than my photon, if you thinking rimfire i would consider a 100/125 maybe 150 mm quality pentax threaded 35mm camera lens with a 2.8 open diaphram, you can pick these up cheap at boot sales/ charity shops/ etc. if you go for a well known make it will have good glass and not so heavy as say a russian lens. back in the 80s i did a lot of 35mm camera work/ printing photos for the local paper.

    Yes - much better suited for air and rimfire ranges than C/F TBH.

    Air in particular is where the shooter needs to be most covert as almost any sound smell or light can alert and sometimes spook the quarry. Scopeless offers the opportunity to stalk it and often shoot it too it without emitting any light source to be spotted - so that is maybe a 30% advantage over a scoped rig that can only be used with IR.

    Longer range sees diminishing returns relative to how much ambient light is around until you use IR. There is less need to be covert at C/F ranges because the quarry often can't hear you nor will it be as concerned about IR lights. C/F needs longer lenses that let in less light so will need IR help more often, though not as much IR as scoped rigs.

    This is what you can expect to see on a night with decent moon - though there are some instances of thick cloud cover. A spankingly decent 75mm lens was used with the HMR. You would only need a 50mm lens for 50 ish yard ranges:
