From that video, I'm almost certain you need more gas, the 2 seconds you filled the mag is not enough, you need to count to 6 with and or Mississippi between them. GHK don't actually recommend filling the mags fully, which I found takes about 8 seconds. They should also be silent fill valves, the hissing sound generally mans you are not sitting home in the valve and putting the gas into the air, not the gun, take care to come vertically and apply a bit of pressure. Also shake the gas can, and make sure it is at least a third full, any less and the pressure drops to almost nothing especially when cold. The video shows it's cycling properly, just venting when has pressure drops low enough to stop it cycling fully. And remember that the dry fire switch is vital to making it work properly.

First off check the very basics: is the gas can a new can or is at at least a third full, any less and you may start running into trouble. It should also take about 6 seconds to fill the mag completely. Less time filling means less gas in the mag. Is the magazine set to dry fire or do you have it sufficiently loaded? The dry fire switch should be on the left of the magazine near the round gas port. Push the follower into the mag to compress the spring then slide the switch foreward locking it down, it shouldn't be protruding out any more. Now it is in dry fire mode. When you put it back together there is a little switch/ lever in the trigger that causes the mech to mimic the bolt picking back when empty, this may be the cause of your issue. Take it apart and split the two halves, with the gun in semi push the biggest part, the hammer so it is flat, Now in the right had side in front of the hammer, next to the striker is a small lever pointing up vertically to twelve o clock, push it towards the front of the gun so it's now closer to eleven o clock. The trigger should now pull crisply and the striker should strike foreward and stay there. Ensure the Mag is out when you test it. Repeat the steps above, reset the hammer and the little lever. Now attach the upper reciever and mate the two halves up. It should already be cocked but pull the charge handel to double check. Now hold it upside down and dry fire it a few times without a mag while looking into the mag well. Ensure the striker comes foreward on the trigger pull and withdraws when manually cocked with the handle. It only has about 6mm travel, but it should be noticeable the two different positions. Now load a mag set to dry fire and test it in semi. Cock it and fire it, it should have shot one shot and reset it's self ready for the next, try a second and third. Flip to auto and test a few bursts. It's very difficult to put it into text and even a video, but it can be a little temperamental and I did have a few problems initially, simply down to me not knowing how it worked. The little lever controls a lot and the dry firing switch can cause problems too. My advise would be to strip it down again and follow the above procedure. If something doesn't go as written, let me know at which point and we can work out the issue.

GHK make the part and sell it as a standalone. G&G fit it to their body and sell it as a factory build GBB, so yes its a genuine GBB, His gun was never built as an AEG, so was never converted to one. http://www.zerooneairsoft.com/product_info.php?products_id=8297

If it has a gas blow back gearbox how is it not a genuine gas blowback? it uses gas and it blows back, just because its a different configuration to other GBBs doesnt make it any less valid. Also it uses an AEG hop up and barrel and mimics the shape of a V2 gearbox, nothing else is interchangeable with an AEG at all, even the fire selector is diffrent.

oops you do need an AEG hop up and barrel. Here is that link: http://www.gtapex.com/08/airsoft_ghk_gbbar.html

Its the GHK GBB internals fitted into a V2 gearbox size, with a redesigned and shortened bolt action, its akin to a closed bolt system. Its not great when compared to more expensive and more modern GBB, but a good compromise and a solid performer. Ammo size you will never win with, carry more mags or learn to shoot better. Mine definitely prefers .25 and .28 over .20. Its strange that you are getting poor range, mine will happily and accurately reach out to 40 meters, (that converts to 60 airsoft meters ) and can be lobbed onto a target up to about 55 ish. The hop up unit isn't brilliant, and isn't forgiving for poor barrel or rubber quality, first off make sure the unit is cleaned and lubricated properly, ensure the feeding nozzel is returning home into the hop up unit fully. you shouldn't be able to see any of the brass tip. if you can you may need to file some of the bolt cover down. The barrel can twist inside the hop up unit and can leak, I sealed the hop up rubber with PTFE and wrapped some around the outside of the rubber to make it a tighter fit in the hop up. It doesn't have the ususal brass ring to stop soem blow past for some reason only known to GHK. G&G green hop up rubber is usually quite good, make sure its in good nick and make sure the nub is still in place, it can fall out when removing the barrel. Similarly the G&G barrels are usually pretty good, give it a good clean with some bog roll and IPA while its out. Its also worth double checking the condition of the O ring piston seal, its not as smooth a bore as I would like, and can get caught and damaged if not heavily and regularly lubricated, There is a good website with an install and strip down guide, I will try to find it for you.

What exactly is the problem? What sort of range are you currently getting?

There is a fairly small but active IPSC style pistol shooting competition scene using airsoft guns, where are you located? Halo Mill in Huddersfield have target sessions every Monday evening, they are a good friendly bunch and shoot everything from completely standard guns to full spec "open class". They have been to European championships and I think have even hosted some high profile comps recently. If you are not local to the Leeds area, you could phone them on a monday evening they may know of someone you can get in touch with.

Most common used screws have a similar metric pitch, so if you have a ruler or vernier guage you can work out what size screws you need if you have one to compare it to. As a rough rule the M Number is the diameter of the shaft of the screw, so an M3 would be 3mm wide, and M6 6mm wide Ect. The length is the length, most screws will need to be cut/ground to the correct length, so always buy longer than you need. Then decide if you need countersunk head which is a v shape, or a rounded head which is a hill shape, or a flat head screw. Then finally decide what head you need a Phillips, flat or allen key. Once you know them, you can nip to your local ironmonger or diy shop and find the correct screws. Its unlikely B&Q will have what you like and halfords will rip you off for very poor fixings. Ebay is a good place to look if you know the correct size you need, Personally if i'm replacing one I like to replace them all. I have used Kayfast a few times, they are pretty good quality and fairly quick to deliver, although not the cheapest.

Yet another example of the corruption that is UKARA.

Where did you get it from? I haven't been able to find any in stock for the last 6 months.

"anbti terror"?

A GHK G5 and 3 more mags. Then a Tactical Tailor Mini Mav and with the change left over to buy the best quality T1 microdot sight I could afford. Or if they were available anywhere a GHK M4 would be on the list, but then I wouldn't have much change for mags.

I'm tempted by this day too, although it is a week before payday and Christmas is looming ....

[Controversial] Am I watching different videos to you guys? Neither of those are what I would call "punches". They were open handed gestures first and foremost. The incident in the second video (4.39) isn't even aggressive, he comes round the corner, gets hit, raises his hand and clips the camera, he clearly clips the camera and not the players face and he clearly does it with an open palm, then stops to apologise immediately. That is not a punch, not aggressive and not pre meditated in any way, shape or form in my book. The first one is a bit less clear cut, and I can see why the "assailant" would be pissed off. First he has come into their spawn, that in its self is frustrating. Second the "victim" is shooting point black inches away from his face, and his very last shot seems aimed directly at his face. It would take an awful lot of tolerance to be happy with that situation. He doesn't punch the guy, he grabs at his chest with an open palm .... my assumption is to stop him from shooting inches away from his face. Now the "victim" is clearly a twit, running and gunning at point blank, rushing spawn points and that shield work speaks for itself. He is the guy I hate playing with and IMO he is in need of being put in his place, however I will never condone that starting a fight is the way to do it. The "assailant" is also a twit for thinking that is the appropriate way to deal with it. To me this comes down to two twitish personalities clashing at the wrong time and place, both parties are in the wrong.

50m?

I think we are overselling the gun again, as far as PayPal is concerned it's not a RIF, it's a toy.

Register your credit card through paypal and have both the banks chargeback protection and paypal coverage.

I did mine with nail polish, it only took about 10min: paint it in, let it dry, then wipe off the excess with acetone.

Not that unique I have the same body, but set up with a different front end.

So who is participating in Movember this year? Its a cause and an idea that really strikes a chord with me, and somewhat of a personal crusade to spread the word and encourage dialogue of issues relating to the modern man. Issues that touch on many levels, from physical health and fitness, to cancers and breeching into the realms of mental health. Attacking the srtigmas of depression and looking at what leads to and the effects of suicide. All while being disguised as a silly, egocentric opportunity to grow a fabulous Moustache, and raise a bit of money for a charity. Note you are not limited to raising money exclusively for the Official Movember charity, many raise money for Cancer Research UK, Teenage Cancer Trust, Samaritans, Macmillan Etc, some don't raise any money at all in favour of spreading the word. http://uk.movember.com/ Periodically I will be sharing post and dialogue to get us thinking about our health and wellbeing, to raise your awareness and make us think, even if it is just for a moment. Please participate, Grow a 'Mo and lets get talking openly. Shall we start off with finding those who are growing a 'Mo, and posting pictures as we go along and as we progress through the month.

Nope, not on mine, it's moulded into the barrel, Maybe they have changed them recently?
