GSG5 full auto, closed bolt conversion?


December 1, 2012, 12:11 PM
First of all, I'd like to ask all posters to refrain from posting the legalities of this subject. I'm not located in the US; I'm an approved full auto collector in Finland, with legal possibilities to convert or build machine guns with an easy and straightforward licensing procedure.

The question is, how, with a GSG5.

I may have done some gunsmithing in my spare time but I'm by no means a professional and rather than trying to figure out a solution myself, I'd rather not re-invent the wheel. There seem to be a number of videos of FA GSG:s on YouTube but contacting the people who have built these guns isn't very easy. I've tried, without success.

I'd prefer a select fire conversion, but a dedicated full auto conversion will be just fine as long as it operates from a closed bolt.

Can anyone help or point me to right direction with this project? Any help is much appreciated.

Are you a member over at rimfirecentral? They have some gurus over there.

I'm not very familiar with the GSG5 design, but you may want to look into the conversion process for a Ruger 10/22 for some ideas. A quick google search should bring up some plans/blueprints. You probably won't be able to exactly copy the plans, but it should give you a good starting point.

Let me rephrase this:

Converting virtually any semiauto firearm to full auto is fairly easy. All you need is an auto sear, means to trigger it by forward movement of the bolt, time it, and possibly a switch to disengage the disconnector if you want a select fire option instead of removing it completely for full auto only. That's all there is to it in theory.

In practice, however, that requires some R&D, trial and error, and can be time consuming. The GSG is just another project, not something I want bad enough to spend countless evenings in garage machining, filing and trying out parts. I wonder if AR15 lightning links were nearly as respected as they are if more people knew what a PITA they are to time properly.

I'll gladly pay someone for blueprints and instructions, the trouble is to find out who that might be. I've googled the subject for years and found little, except a number of people on YouTube who seem to be elusive as far as contact information is concerned. Instead of consulting an expert of the subject in general I'd much rather talk to someone who already has done it with a GSG5.

Let me see what I can work out. We have a shop GSG, I'll get inside and play with it. Maybe I'll convert it to FA while I'm at it, and see what it really takes

How close is the GSG5 to a real MP5? You might just be able to modify or fit a MP5 trigger group.

im pretty sure its very different. isnt the gsg blow back and the mp5 a roller?

Dan Block, FFL/SOT in Iowa has done them.
