| I just got a new GSG-522 and I was wondering about the screw mod that I've seen a lot. Now that the GSG has been manufactured for several years have they improved the screws they use or is the screw mod still recommended? |
| i think some screws have changed b/c i got a screw kit and some screws didn't fit. the top 3 screws for the bolt once you've gotten it apart, they're the silver ones, those are now bigger than what was offered in the kit. also, i have a GSG522PK, and there are two screws now that hold in the cocking tube. all the screws that hold together the bolt are the same size and thread pattern. good luck replacing them! it is easy and there are guides online on how to do it. i recommend doing it in a flat open area b/c you may lose a spring or two. i was converting my GSG522 to a GSG5 w/ the conversion kit the same night. did it in around an hour before i realized there are guides online. |
| Every GSG should have the screw mod and cocking handle buffer mod. When I did my screw mod I could tell the original ones were garbage. I used a rubber hose washer or two from a Menards/Home Depot pluming department. I dont remember the exact dimensions but they fit right in and my handle never strikes the reciever. Only cost 50 cents as opposed to whatever online costs for a piece of delrin. When you do the screw mod make sure you get the bolt springs in the correct way. One end is tapered, the other belled out like a trumpet. I forget which way goes which, but pay attention when you disassemble. If you get it backwards you will get one shot before you have a huge jam. Trust me, I know from experience dude. |

Small end of the spring goes over the guide rod.
If you do the screw mod be sure to Loctite them. I did mine without Loctite and I tore it down today after about 3000 rounds. One of the screws in the bolt jacket was gone. Fortunately I dumped it out of the trigger group and still had it. I applied Loctite on them this time.

If the screw mod is such a great thing, why doesn't ATI do it? I also read some place by doing the screw mod you will void your warranty?
Primarily because we are just the importer and it is not our call to alter the manufacturer's design & process. If you do not tear down your carrier assembly further than the instructions dictate, then you will not have screws backing out that require the 'upgrade.' We will only void the warranty on the upgrade if it is the cause of the failure. As we have only had this be the case once in I don't even know in how many guns, we really don't have any issues if you want to change. That said though, if the upgrade screws cause the issue, or if you require us to reassemble your assembly etc because of taking it down to swap these screws, that sort of thing is outside of GSG's warranty. |
| I don't know if I'd mess with a brand new GSG as far as the screw mod. If it works perfectly, leave it alone. I bought a used 1st gen from a gun shop (for a steal) and I'm glad I decided to do the mod. It had the occasional FTE/Stove pipe issues but got worse and worse over the first ~250 rounds so I tore the gun down and found EVERY single bolt loose. And I don't mean hand tight. I mean the head backed off the metal on almost every single one. The used rifle didn't come with the orange tool so I'm glad I got the hex screw kit and Loctited everything. |
| +1 for the screw mod. I've done it on all 3 of my guns (5, PK, P) and have had zero issues with feeding unless using crap ammo. I did the guides to install that most folks use HERE Feel free to msg me if you have any install questions |

Thanks everyone for the comments, I favorited that video for reference and will be ordering the new screw set. Remember its a four-part series... stupid Youtube won't let you upload anything over 10 minutes lol. You won't regret the screw update for sure. |
| rrages.com has both the push pins and screws for the screw mod. You can do both, yes. The push pins replace those two part screws that hold on the stock, front furniture and the lower to the receiver. Personally, I'd do both. Those two part screws are kinda cheap. |
| Given the topic, I thought it might be appropriate to ask my question as part of this thread. I was working on the screw replacement (in addition to installing the cocking tube buffer and push pins ) and all was going well until I got to the 3 little screws that secure the bolt jacket...I torqued down a bit too hard on one of the replacement screws and stripped the threads. The good news (if there is any) is it appears that I stripped the threads on the replacement screw and not the bolt since I was able to back the screw out and the reinstall the factory bolt jacket screws (using Blue Loctite). I did order a second set of replacement screws but my questions is...should I attempt to replace the factory bolt jacket screws again now or wait / check them periodically / replace them if I notice they're coming loose? Also, if the concern with cracked bolt jacket covers is linked to the 3 bolt jacket screws working loose, why not use Red Loctite? |
