Basic-Wedge Posted October 21, 2011 Report Share Posted October 21, 2011 So Henning, it sounds like you wrapped too much Teflon tape around the bucking. That would explain why it was so difficult to slip the barrel assembly back into its metal housing. I found that too, when I tried to wrap my bucking the first time. A thin wrap of tape is all it needs - and all that will fit. I am convinced the Teflon tape is needed to help form a good gas seal. I also installed a shredder nub in my rifle. It helped reduce the over-hop, but only by a little bit. I think the problem is that the bucking has a nub already molded in to it. Adding an additional nub creates over-hop. The next time I take my rifle apart I'm going to see about reducing the molded-in nub portion. I'll have to look at it some more before I decide which tool would do the job best. Maybe a Dremel? We'll see... Let us know where you find a new dial for your hop-up unit. Quote Link to post Share on other sites
calbur20 Posted October 22, 2011 Report Share Posted October 22, 2011 Anyone experience your gun light striking when full of gas? It's an annoying problem that comes and goes, but the past few weeks it's been really pronounced. Filled my mags full of gas and then the gun light strikes. I take out a bit of gas, the gun shoots fine again, after a while it light strikes again. What could be the issue? Quote Link to post Share on other sites
bbstriker Posted October 22, 2011 Report Share Posted October 22, 2011 Maybe you need to upgrade the hammer spring? Quote Link to post Share on other sites

That or the temperature of the mag is too hot causing high pressure so that the valve release needs more strength to open It happens to my G39 mag as well as KSC MP7 before.

mnmc10 Posted October 23, 2011 Report Share Posted October 23, 2011 overfilled, over time the magazine is easier to fill. and our weather lately in the philippines is hot. try this, from empty fill it with gas for 10 secs only. see if it can finish 30 rounds. i usually fill mine for 15 secs,has enough gas to finish 30++ rounds.

calbur20 Posted October 23, 2011 Report Share Posted October 23, 2011 Maybe you need to upgrade the hammer spring? It was working perfectly fine before, swapped out a brand new one just in case and it was still the same. overfilled, over time the magazine is easier to fill. and our weather lately in the philippines is hot. try this, from empty fill it with gas for 10 secs only. see if it can finish 30 rounds. i usually fill mine for 15 secs,has enough gas to finish 30++ rounds. Aha, will try this next time. Though my love affair with the gun is almost at a close since I got the OB kit for the M4, I'm already thinking of selling it, especially since there isn't any easy way to store the mags without them catching on mag pouches.

mnmc10 Posted October 23, 2011 Report Share Posted October 23, 2011 yeah i saw it over at fas, i also converted my m4 to OB. m4 performs at par with my g39c, but i will keep my g39c simply cause of the leakproof magazines. Quote Link to post Share on other sites
DFM56 Posted October 26, 2011 Report Share Posted October 26, 2011 So, I'm looking into the G39K. Anyone know where I can get the KAC sight base and the idz stock? Also, someone posted a while ago about fitting the mag internals into magpul g36 mag shells, did anyone get around to trying this? Quote Link to post Share on other sites
Basic-Wedge Posted October 29, 2011 Report Share Posted October 29, 2011 (edited) You should be able to find IdZ components at most of the large airsoft vendors. Until you mentioned it, I didn't realize Magpul was making mags for the G36. Such real steel mags are banned in my country, so I'll have to wait for someone else to try modding one. Looks super nice.

kullwarrior Posted October 30, 2011 Report Share Posted October 30, 2011 You can get the mags if its pin to 5 rounds or you undergo destructive mod to the feed lip (ie cut, sand to the point where you feedlips are not even present) Quote Link to post Share on other sites
Basic-Wedge Posted October 30, 2011 Report Share Posted October 30, 2011 Hey Kullwarrior, I see your G39 mags are up for sale. Did you sell your rifle? Quote Link to post Share on other sites
kullwarrior Posted October 31, 2011 Report Share Posted October 31, 2011 Hey Kullwarrior, I see your G39 mags are up for sale. Did you sell your rifle? Nope, if you're interested to buy it let me know Quote Link to post Share on other sites
Basic-Wedge Posted October 31, 2011 Report Share Posted October 31, 2011 Nope, if you're interested to buy it let me know Oh sure! All I need is for my wife to see yet another G36 added to the pile! Quote Link to post Share on other sites
Zlyth Posted November 4, 2011 Report Share Posted November 4, 2011 Don't really feel like digging through 61 pages, so: How reliable is this gun? Will it break within 10k rounds? Quote Link to post Share on other sites
NonEx Posted November 4, 2011 Report Share Posted November 4, 2011 Trigger group "breakage" confirmed at 10-12K rounds, meaning the pot metal trigger components wear down and affect the guns functionality, ie. full auto in semi and maybe vice versa or not firing properly at all. Other than that, I haven't heard or seen much of any complaints really. I owned one briefly and it was a nice piece, sold it for other reasons. Quote Link to post Share on other sites
Zlyth Posted November 5, 2011 Report Share Posted November 5, 2011 I appreciate the quick reply. I'm thinking that this will be my first ever gas gun, and I don't want it to break to easily. Anyway, thanks. Quote Link to post Share on other sites
mnmc10 Posted November 5, 2011 Report Share Posted November 5, 2011 you wont regret it cause it is the easiest gbbr to maintain for a newbie. but you do have to dig thru all 61 pages cause there are really valuable stuff you need to know about the g39c. Quote Link to post Share on other sites
ryangolfvr6 Posted November 5, 2011 Report Share Posted November 5, 2011 All I will say is that its a great gun and overall proberly one of the least problamatic we gbbr on the market at this point in time. On the other hand is something does break it can be a pain to source replacement parts and when you do they could be out of stock or people want heavy price to ship them to you Quote Link to post Share on other sites
Leshy Posted November 5, 2011 Report Share Posted November 5, 2011 I don't have a G39 but keep a close eye on this topic for a possible future purchase. The issue with the over hop with .25, I use .30 as standard would that flatten out the trajector? PDI make trigger parts so that should improve reliability! Quote Link to post Share on other sites

Far-T Posted November 14, 2011 Report Share Posted November 14, 2011 Alright guys, My G39 has decided to stop working right. Stripped it down and part #91 in the trigger mech has snapped. The same thing has happened to my mates aswell. This is the part: http://i305.photobucket.com/albums/nn212/ChrisBenham45/IMAG0119.jpg I've looked on a few websites but cannot find this part anywhere! Can anyone help? Cheers Quote Link to post Share on other sites
ManMarin3 Posted November 14, 2011 Report Share Posted November 14, 2011 it's the delayer, same as part 66 for the M4, just make you get the OB version of the part or you will have to use the old style firing pin aswell Quote Link to post Share on other sites
Reppyboyo Posted November 14, 2011 Report Share Posted November 14, 2011 Its not the same as the M4, the design is slightly different. These guys should have it: http://www.blowbackarmory.net/category_s/46.htm Quote Link to post Share on other sites
danielsilva Posted November 14, 2011 Report Share Posted November 14, 2011 I do believe that it is identical to the new open bolt m4, it work won't with the new type firing pin but you can still use the old one if you use both old type valve delayer and firing pin.

Wild_XIII Posted December 8, 2011 Report Share Posted December 8, 2011 I've been through the places suggested on here for replacement parts however still I'm down a couple of bits on my G39c. The roller on top of the hammer has gone walkies (ironically the tiny pin that holds it in didn't disappear!) and the hop arm has snapped meaning I have no hop. Any ideas where I can get the parts?
