Hi all I have read I think all the tips and tried them and hoping someone knows what my issue may be and how to fix it.
I got one of the pre-lawsuit GSG-5's a few years ago, but its the newer model with the ejector rivoted in place and is still solid. I don't get alot of time to test and fire the thing and the gun has had the issue since I got it. My problem: Using the stock, third party or Drum mags the gun jams when feeding the shell into the barrel and the breech doesn't fully push the shell into the barrel and causes jams. If I keep slamming the breech by opening and closing the charging handle it eventually pushes the shell into the barrel and the gun will cycle normally again for a few rounds and may do it again. I have cleaned the gun, breech, barrel, mags, etc. I have sanded down the Mags, replaced the screws on the breech with upgrade kit and everything is solid with loctite. The springs are in the correct position and not pinched and everything is in line and tight. I'm not holding the mag or drum when shooting and have tried various ammo types as well from CCI Mini Mags, Thunderbolt, Golden Bullets, Blazers, to the recommended Federal 550 and 525 value packs and they all jam the gun. Anyone know what the issue could be? Makes me think its the springs in the breech or something out of line. The breech shouldn't have any problems pushing that bullet into the barrel, so not sure what is going on. Any help is appreciated Thanks, Dan |
| So if I read correctly this happens with the OEM 22 round mags and the drum? I am only assuming as of now that this is mag related. If you have a friend that has one meet up with them and try swapping mags and see if the problem transfers to their weapon or not. |

Don't know anyone else that has the gun. Yea its the problem with 1 OEM mag, two pro mags and a new ATI Drum. I sanded down the mags like people say on the internet and no luck. Just had the drum replaced by ATI last week, would hope they have them fixed by now. I was thinking of purchasing another OEM German Sports 22 rnd clip, but hate to waste anymore money. I'm about to send it back to ATI and see what they come up with, but if its something I can fix I'd like to figure it out. Not really much to the gun so I can't imagine it being a hard fix.
Thanks, Dan |

Problem One: Bullet gets jammed into top of barrel by breech. Can see the tip of the bullet mushroomed into top barrel and the shell gets bent. Like its feeding from the Magazines wrong at points. Have 3 22 round magazines and one drum and happens with all of them randomly.

This may be related to problem one and the shell getting bent. See the last two pictures on the bent shell. https://dl.dropboxusercontent.com/u/18068810/IMG_0454.jpg https://dl.dropboxusercontent.com/u/18068810/IMG_0455.jpg https://dl.dropboxusercontent.com/u/18068810/IMG_0456.jpg Bent bullet/shell casing from Problem 1 pics: https://dl.dropboxusercontent.com/u/18068810/IMG_0457.jpg https://dl.dropboxusercontent.com/u/18068810/IMG_0458.jpg Before this session of shooting I completely stripped down the mags and sanded them down and they move very smooth. Have cleaned the gun end tried dropping a drop of oil at the guides there at the beginning of the barrel and tried all kinds of things. Clips are pushed in the full way and not being used to hold the gun up to shoot. |
| I think your bullet giude may be off and the only fix for that is to contact ati and send this info pics and all to them link to this thread if you like. They should get you taken care of. I wish it was somthing simple but unless the barrel is loose then I think your bullet giude is causeing this. |

How dirty is that feed ramp? Just looks like the carbon buildup may be directing the round at too much of an angle and if the chamber and chamber throat isnt squeaky clean, rounds could hang up.
After I run 4 or 5 mags, I take the nylon chamber brush and brush it out...other wise I notice I start having trouble loading rounds into the chamber (as shown in one of your pics with the bolt not fully closed) and getting them out |

Have you tried running it wet? That bolt looks awful dry. I have a savage that'll jam just like the first pics when it gets dry and gummed up from firing sub sonics. Yea, last week and lubed it all up and tried that and still same issues. Thanks for the response! |

After I run 4 or 5 mags, I take the nylon chamber brush and brush it out...other wise I notice I start having trouble loading rounds into the chamber (as shown in one of your pics with the bolt not fully closed) and getting them out I tore down the whole gun and cleaned it before these pics, if it looks dirty its from the rounds from that day which was maybe 150 rounds or so. I was trying a couple of drops on the breech guide, which may have contributed to that look as well. That round that is mushroomed into the barrel was the first clip after about 10 rounds or so. On the second clip is when the other bullet got stuck and I had to keep charging the gun. I had one round I noticed where it was tilted way up while it was in the magazine and when you slowly closed the breech the back of the casing kicked up into the breech and then everything went smoothly. If that bullet isn't coming out of the magazine correctly and the casing doesn't get kicked up into the breech then that is when it jams the bullet into the top of the barrel like in those first pics I believe and bends the casing and causing all this I am guessing. But like I said before I have 3 22 round mags and one drum mag and all are clean and sanded and run smoothly, I'm not sure how they would get screwed up coming out of the mag like that. |
| I would try a little polish on the feed ramp. I have had some great luck using bike chain lube from walmart on the Mags its called lightening or lightening bolt goes on wet then leaves a nice slick wax behind for lube helps the mags feed better I also used a dremel and polish compound on my mags to smooth it out. I would try running a little Mobile 1 5w 30 for lube on the bolt |

I ripped the whole thing apart and have the breech torn down to the firing pin and cleaned everything up real good. One thing that has always bugged me is the two sides of the breech housing would teeter/totter when putting them together, even empty. The front would look correct looking down on it from the top, but the rear where the nut is would have a noticeable split and the sides wouldn't touch. I never thought that was right and could never get it correct, even "without" the nut in place it would still do it, like one of the breech housing sides were bent or something. Not sure what caused it, but this is my first time tearing it down to the firing pin and tearing the whole thing apart.
Late last night I used some CLP on the parts and left it set for a few hours and today I cleaned everything up and the breech housing is fitting together now! Not sure what was holding it and making it teeter/totter as I sanded and checked everything over and over before. Only thing I never did before was take the breech fully down to the firing pin. So maybe that plate around the serial was off or something, I don't know. I'm curious if thats been the issue this whole time? Not sure though, would think if that was the problem I would have issues on every round, but who knows. I stripped a hex screw head so waiting on a screw upgrade kit to replace it and hopefully get some time to test fire it. I have my doubts, but hoping that was the issue, as its the only thing that seems off to me. Forgot about this hole as well, I found when I removed some loctite that built up around the screw head. I noticed the other side as well looks like it will have the same issue. I don't think this was causing any issues or will, but troublesome. I think I got a lemon here! http://www.ar15.com/forums/t_6_41/403900_Breech_Body_Hole_ever_been_a_recall_.html |

I think I got a lemon here! http://www.ar15.com/forums/t_6_41/403900_Breech_Body_Hole_ever_been_a_recall_.html Well I finally got to shoot today! Put 90 rounds through it with 3 clips and no jams for once! I had to recharge it 3 times, but I think it was from the weak springs in the ProMags. The stock mag ran fine! I also did most of the mods out there like the magazine mod, hammer strut mod, trigger pull tightened up, cut off the magazine safety on the inside so its not engaged, but still puts pressure on the mag. Read that doing it the other way by completely removing it or cutting the tip off against the mag some people talked about the mag being loose, so did it my own way. Another thing and I feel stupid, but the magazine mod I mis-understood! You have to take the mags apart and the little nubs that you use your thumb on to push the spring down to load the magazine you have to set the nubs in the track of the magazine sides they sit in and see if they freely move up and down in the track they sit in. Mine were bad and catching like crazy, so I sanded down the tracks the nubs slide in and they move freely now, which was probably the whole problem all this time. I might try and replace the springs on those promags with the GSG ones or just replace them all together and see what happens after that. Hopefully 0 jams and 0 times having to recharge it! |
