Okay, so I got back from my skirmish and decided to clean out the barrel. I did the normal procedure but I noticed that the barrel assembly was a bit loose. The body pin was also almost out so I decided to open the gun up for the first time to have a look-see. I found out that the kind lads at MIA had taken a little lazy shortcut and drilled the piston. :mad: but that's beside the point.
So I just popped the upper receiver back in place and continued to clean the barrel. I normally re-adjust the hop-up before I put it away so I put in a fresh mag and fired away.
PROBLEM - My gun isn't feeding quite right. In semi-auto it goes ok for about ten shots then starts to dry-fire and double feed. I have never encountered any problems of such before and have no idea what it could be? Approx How much would it be for a gun tech to fix the gun? Any tips?
If it helps the gun is just over a year old and skirmished about 4-5 times.
Don't suppose the spring that separates the hop-up chamber from the receiver fell out while you dismantled it?
If you bring it to a tech, get yourself a new cylinder and spring. Your better off. No doubt this will open a tin of worms soon.

You seem to be onto something there. Although I didn't see spring there at all ?0 -

Can you tell me how to do so? I have no experience and would like some help.:o
hmm
. it may the spring but my G&G Raider has no spring and it never mis feeds.
I can walk you through it but tbh it's prob best to get a youtube video, or bring it to a retailer, if it's not too busy they may be able to do it there and then for ya, it's a 5 mins job. If you're up to it I'll post up a walkthrough for you?0 -

Yeah I didn't even see the spring in the first place. I'd be delighted if you had the time to do that for me But I'd rather fix this gun and use it for the next few months before getting a new one. 0 -

What is the 'normal' procedure that you followed? And which barrel assemble; inner or outer?
In all likelihood you will have pushed your hop up chamber and rubber slightly off of the inner barrel, resulting in your feeding problems. It happened a lad in the store the other week, though he had torn the hop up rubber as well.
If you're confident doing a bit of tinkering, all you have to do is separate the receivers, remove the inner barrel and hop up assembly, pop off the green circlip and remove the barrel from the hop up chamber (be sure to hold the chamber upside down) - apply downward pressure as you remove the barrel to take the hop rubber out with it.
Inspect the rubber, and provided it's not torn then reseat the hop rubber (there's a line in the rubber and on the barrel; you simply push it back on so that the mound sites inside the window in the barrel, and then you put the barrel back inside the hop chamber (there's a seam line on the chamber; keep the line in the barrel in line with that seam line) and then pop the circlop back on & test 0 -

even if you did loose the spring just take one out of a pen (the little spring found at the tip of the clicky pens) it may not fit perfectly but try it and see if it makes a difference.
aas fort he hop up:
1) first thing is to obviously take the inner barrel out and move the aEG and anything else out of the way, some of the parts are pretty freakin' small
2) to start. unscrew the small screw found on the plastic gear (the one you turn to adjust the hop up).
then remove the other plastic gears on the outside of the chamber (use a flat head to remove the metal discs holding the gears together (I'm trying to do this form memory as I don't have on infront of me, so some of it may be a little off :P)
3: take the gears off ( they hold each other together due to their design to start with the adjusting wheel removal then work from there). once they're off there should be a little silver pin towards the back of the chamber. take this off and you should be able to take out the arm that adjusts your hop up (the one at the top which pushes down into the chamber). NOTE: be careful taking the arm out, the hop up nub sits in that and it's tiny so don't loose it
4)now flip the chamber upside and there should be a little plastic C-clip (it holds the inner barrel steady and you'll find it on the bottom of the hop up chamber towards the barrel, it being a G&G I'd say it's green)
5) once that's out, the whole barrel will come out. there is a rubber at the end of this but it's petty hard to loose.
6) now makes sure none of the rubber parts are torn and if you wanted to this is a perfect time to clean the inner barrel properly.
7) to put the barrel back together, look into the rubber that was on the inner barrel and you should see a little raised area running along the inside fromw here you;re looking to what would then be the back, this raised area, will sit into the barrel which as a matching groove, makes sure that sites correctly before re-assembly.
the rest of the hop up chamber is just the reverse of what i posted.
I hope this helps mate0 -

I sometimes use G&G but not all the time. maybe one bag of G&G every 6 bags of the cheap ones
right I'm not going to say anything about your current BB's that's not fair on the retailers but swap to .20g king arms BB's and see how you get on. if you knwo anyone around that plays airsoft that uses them, try and use their BB's and see if it makes a difference with the KA BB's
Also I really wouldn't mix BB's of different brand, i may just be over cautious but I'd advise against it 0 -
I understand what you're trying to say But I have been mostly using these and haven't given me a problem before. I just can't see it... I will definitely try upgrade to better BBs tho because I seem to be using less and less every time I skirmish.. 0

could be a bad batch, try switching and see what happens.
mis feeds and double feeding is 9 out of 10 times down the either the BB or the hop up.0 -

Guys, what do you think of the ASG Blaster BBs as here? - http://www.airsofteire.com/index.php?page=shop.product_details&flypage=shop.flypage&product_id=405&category_id=48&manufacturer_id=0&option=com_virtuemart&Itemid=26
EDIT - Doesn't matter probably won't buy them anyways
I used them when i first started but switched to KA's (well G&G's at first then to King Arms). if you want possible THE BB go for Excels. but before you start tinkering with the AEG more try a different brand like the ones I and others have mentioned 0 -

Lads just an update to keep you posted. I got the usual G&G .2s and ran about 400 rounds in semi and full auto throught the gun and not one misfeed or double feed! Turns out it was the BBs after all. Thanks for all the suggestions, greatly appreciated. I am one happy bas***d knowing I won't have to spend a ****eload of money again. (for a while at least)
glad to hear you got it sorted so 0 -

I will definitely try use some KA instead of the cheaper ones. The G&G ones I use sometimes are pretty good, yeah Advertisement
