g36 hop-up assembly
 

ok so i finally got my hop up rubbers and am going to be attempting to assemble the hop units on my two sl-8's.
im not exactly sure how to assemble them correctly so and tips or help from anyone whos put one of these together before would be really appreciated

I found the hardest part is trying to slide the barrel and hopup sleeve into the chamber without stretching the sleeve. I used some silicone oil to help slide it in. Be careful not to force it or you'll tear the sleeve. Also use your finger to feel and match the groove you see on the sleeve to the grove in the barrel. Make sure it is in the groove.

silicone oil.....sounds like a good idea. i dont have any
can you buy some at a walmart?
i saved the hop up guide in my favorites. im not gonna attempt anything til i can get some of that oil

hmm it has to be a very light silicone oil. I'm not sure of other oils to use, this maybe possible since you just needs something to help the barrel and sleeve slide in. Maybe in walmarts in the USA have some more airsoft stuff then Canada Walmarts? Maybe they sell light oil in the Paintball section?

Haha wow... I was also wondering how to assemble a G36 hop up and oddly enough I had seen that guide yesterday, but it never hit me.

Sorry for the thread jack, but I still have to find a good hop up for my soon to be CA36; I'm upgrading everything in it and I heard the Pro-win hop up is good, can anyone vouch for this?

Even more coincidence: I am checking out g36c hop up assemblies and just cylinders.
SO far the prowin seems to have issues for some people, http://airsoftcanada.com/showthread....ghlight=prowin
another metal one I saw online has no airseal. I think it was $30 and is made by SRC,
and there is an unkonwn (I can't find a review for it) $50 metal one that needs magwell moded made by bestgun. http://store.matrixbb.com/servlet/-s...l-Metal/Detail

I am tempted to go for the prowin and not use the screw to the mechbox, or just go with the known and buy a CA plastic one for $30

Damn... so many choices, so much uncertainty! Heh heh, would you dare to say that G36's are becoming rather fashionable and may even be the new Armalite? :P I think I'll stick with my stock hop up until I can find something worth buying/ if they perfect pro-win hop ups.

If you do get something good, care to PM me and discuss it?

no problem. If I get a prowin which could happen in the next while (if my current stock hop up fails) then I'll pm you, especially if I encounter problems. Probably post solution in a thread too.

I have no issues with the stock CA36 hop-up. It works and seals quite well.

I am installing a Prowin next week in my friend's G36C.

As for oil, go to any hobbyshop, they should carry some silicon oil. Some 10wt shock oil will work for that, but not for gas mag oiling.

You can get some from Airsoft Innovation too.

See thats my delima. I know the CA abs hopup seals well but it sells for $25-$30 as an assembly. The prowin is around $35. So $10 more for a CNC metal hopup with less liklihood of breaking the tabs but it might need modding.

Kos-Mos let us know how it goes and if you found any problems. thanks.

ok let me verify this. you first put the rubber sleeve into the hop mechanism before sliding it onto the barrel correct? im still a little confused about where that little rubber piece goes.
see my hop up is pretty close to that ca one i posted but its not 100% the same

I tried that way but there way no way I was going to slide the barrel into that lol. Maybe yours is more forgiving?
I put the sleeve onto the barrel first and matched the groove, then using a Qtip with silicone oil on it I lubed the interior of the chamber and on the exterior of the sleeve. THen I slid the barrel+sleeve into the Chamber. Then you have to watch that the sleeve end (where the bb goes in) is perfectly round and not crooked hole. Also you need to check that the sleeve is not overstretched by checking when you insert the hopup nub how much it shows in the barel when you look down the barrel.

Also you check check streching if the sleeve is streched too much by the clip. If you can't put the clip onto the barrel because the sleeve is sticking out and in the way, that means the sleeve is too streched. Try not to rip the sleeve if you insert it poorly and need to pull it back out to try again.

Well, just my two cents, if I was going to replace a bunch of parts anyway migth as well spend the extra doe for a superior product. The way mine sits is that as long as it works I won't replace it, but if it ever needs replacing I'll spend the extra on the metal unit.

You have to put the rubber on the end of the barrel BEFORE trying to insert the assembly.

Because the little nub that cause hop-up needs to be in the groove on the barrel, otherwise, it won't fit.

You can go slowly, and move back a forth a little bit to place the rubber correctly.

Then, insert the bucking, the little plastic lever and the adjustment nob.
You only have left to clip the holder in place.

i put the thing together. not as hard as i thought. didnt need no oil or nothing, i just wiggled it down over the barrel. no rubber stretching or anything like that. went together way easy.
gun still doesnt shoot correctly. still clogging and burping out bbs

i dunno if anyones familiar with be body parts. i have a feeling that its cuz im using an x-m8 barrel assembly in my sl-8 even though the two barrel assemblies are identical except for the flash hider tips.
i can put the other sl-8 barrel assembly in both of the guns and it shoots fine even thought its hop up rubber is broke and i havent replaced it yet.
im rather stumped on why the identical x-m8 barrel assemby doesnt work in the sl8

Maybe it's because it's a BE and BE makes complete shit guns? Seriously dude... how many times have we told you that CHEAP = SHITTY.

ive been replacing the inside parts. cut me some slack, this is my very first aeg project.
the one sl-8 works fine. if i cant work the bugs out of the other or rig something to work then i could always scrap that and try to put it together in my brothers x-m8 body and see if things are any different.

gives me something to do which is good

If you have ruled out the burping is not due to an internal mechbox problem (bad tappet plate,etc) and think it is being caused because of bad feeding or hopup, maybe I can give you ideas of what to test.

There is a balance that has to be maintained between the nozzle, the hopup and magwell hole feeding for proper function.. First the bb must be able to fall straight through the magwell with gun upside down. I used a flashlight to confirm thisand dropped bb in.

Then I checked that the nozzle when fully forwards (I have a modify antireversal latch with flat head screwdriver slot-- makes life easy) touches the hopup rubber and seals and does not leave a gap. You can shine a light down your magwell and look down your barrel with safety glasses on an see if any light shines through. Proper seal, no light.

In case you changed nozzle, did you check the length of the old and new nozzle size by side? In my case the guarder nozzle I purchased is slightly shorter and does not seal with the hopup sleeve. So now my option is to shave a little off the hopup chamber so it sits closer to the front of the mechbox and seals with the nozzle better and shave the same amount off the hopup chamber tabs to allow the chamber to move farther back due to the barrel spring. Until I fix the problem I have about 250 FPS. Dents the side of a sprite can lol.


Also so people recommend putting in a stronger tiny spring in the hopup chamber (the spring that pushes the plastic piece which goes down when a bb is fed. SO people put in a stronger spring to prevent multifeeds. I have no idea where they found a tiny stronger spring but if had to I'd add some epoxy to it behind the spring to push the spring foward and make it tougher to push the plastic piece down.

Other than those off the top of my head tests I'd take it to a gun doctor.

forgot to mention. Turn your hop upp all the way down (off) and see if burping is diminished.

yea im pretty sure it has to do with the barrel assembly. cuz like i said before, the sl8 one works fine with both guns while the xm8 one works with neither. it seems as though i will have to fix the broken sl8 barrel assembly that went with the other and see if it works then
i also had thought that maybe the nozzle on either my ca or echo 1 gearboxes were shorter than the other. but since the sl8 barrel works fine on both of them i do not think that that is the problem

oh and i looked at that little spring you mentioned. you could probly use the spring out of a multiple color pen to make that stronger

at this point i really dunno what the problem is. i can turn the gun upside down and drop a bb into the chamber and pull the trigger and it shoots perfectly no matter which barrel i have in it

get this....... i took the sl8 apart and took the hop off the sl8 barrel and put it back on the xm8 barrel, stuck the ca g36 gearbox in my bros xm8 body put it all together and it works wonderfully
....................go figure

What magazines are you using? The stock SL8 ones?

oh yea i have three stock be ones and a be hi cap winder that are designed for g36 and xm8 models
but hey its all good. i took that sl8 apart and put all the internals into the xm8 body and it shoots wonderfully now. my brother is happy with it

the sl8's broken barrel shot fine with the xm8 and i was like thats cool but i dont like the looks of the end of it being all broke off. so i took the hop up off that and put it back on the xm8's barrel assembly.
i think the problem was either that particular sl8's magwell since its removable or the fact that the gearbox was secure in the sl8 body which that part that holds it in place with the gun bodies pins i had to remove off the gearbox to fit into the xm8. my echo 1 gearbox didnt come with one of those plates on it. now both of our guns have functional safteys cept for the locked trigger part

I have the same hop up assembly as that little picture in the first post. I dont know which order to put the things back on...i looked at the guide too but it seems to be kind of different than mine because i cannot just simply slide the brass ring back on.

Sorry im not trying to jack yout thread but i am having the same problem

Put the brass ring over the end of the barrel and slide it down.
