conversion of a M93R into an Auto 9

I am building an Auto 9 from a KSC M93R and a cheaper (than the KSC one) airsoft version of the Auto 9.
This is what it looks like at the moment:



I already had to make a few changes to the barrel extension, and I also had to remove the front sight of the M93R slide, and the 'block' on which the pull-down-handle is attached to, but as you can see in the pictures, there are still some other points I will need to pay attention to:

First of all there is some kind of text on the barrel extension that I need to remove. Don't know how to do it yet, but I think I wil 'Dremel' this out of it.

Then the grips (see below picture). This doesn't really look nice, does it?! Anyone any idea to solve this problem?



Also another problem with the grips, is that they are hollow on the inside. This means that the 2 parts in the next picture are coming loose every time, and they just fall out when I remove the magazine from the gun. I absolutely have no idea on this problem.



The hole in the barrel extension and in the M93R don't match.
Think I can just stretch the hole in the barrel extension. Still have to make a pin to put in these holes, so I think I can cover the left side of the hole in the barrel extension with the pin.

Hmmm , I unscrewed the grips of my other M93R, and it seems that the part near the upper red arrow in the picture above is not in the right position. It should be turned about 120° clockwise
It also seems that I am missing a little spring that needs to sit in the deeper rectangular cutout at the left of the mag release button.
But does anyone know what this part+spring do in the correct position????

Its the part that controls the three round bursts ..take it away and it goes full auto

Haha, that's just what an Auto9 needs
Thanks for telling me! I just don't see how it should do it's job

I've been working at my conversion for about 6 hours today. I hope it will be finished at the end of this week!
Photos will be on here as soon as it's finished and painted!

It controls the movement of the piece that it is sitting on ( the bit with the saw like teeth) that piece moves one tooth for every shot on the three round burst and after three it resets via the " L " shaped bit and spring

As promised some pictures of my finished Auto 9:

Hi Yellow,

You have done a great job there matey ,that looks absolutely superb,I like the way that modelguns can be changed into so much more......perhaps a nice video to finish it off

Great stuff

Kickback

Is that the same gun??? You really have done a great job there, you definately do deserve a pat on the back. How does the gun feel and fire now that you have finished all that work on it? Also, how did you get such a nice smooth finish on the front end where you removed the writing?

Thanks guys I'm very happy with it myself too!
It feels absolutely great. It's quite heavy as there are some metal pieces in the barrel extension to make it heavier, but it's still balanced very well.

Spencer-man: yes is is the same gun
To re-locate the holes of the grips, I just 'dremel-ed' the right positions as you can see in the first pictures. Then I glued a little piece of plastic on the backside of the grips, and I used putty (as you also use for carbody repairs) to make everything smooth.
Also the writings were 'dremel-ed' away, and I also used putty on that. After sanding I used a spayable kind of putty, sanded it again, sprayed a primer, sanded it again, and finally I sprayed the paint on.
The only thing I regret is that the barrel extension is not that matt finish as the grips and the rear view. I used the same primer and the same paint. I already re-sanded the barrel extension to spray another thin layer of paint on it, but still te same. Maybe in the future I will redo the barrel extension completely.

Fantastic job yellow mate really good got to say i would like one of those myself but i am completly crap at doing stuff like this and have to rely on a couple of good friends to keep my stuff running.

Lovely!

I need to do something like that some day :-)

Very, very nice, I like that

Congratulations yellow, you should be proud of the work and effort you put into that Well done

I'd buy that for a dollar

come on was i the only person thinking it

An outstanding conversion

Thanks again...

Yes I AM proud of it
I estimate that I've worked about 35 hours to get it fitted and painted, so it DOES feel great holding it!!!
Maybe it would have been easier with a KSC airsoft auto 9, but why do it the easy way if you can make it difficult??

I never doubted that it wasnt, just that it is such a long way from what it started as at the top of the thread, really a fantastic job. Now, be really honest, have you tried to spin it round your finger yet?

Hahaha, no I haven't

Have you fired it since the conversion how did the added on parts hold up ?

DOC

No I haven't fired it yet at all, not even before the conversion.
I guess I'm much tooooo afraid with my modelguns. I've already read some threads with problems like broken slides, broken firing pins, etc. and I just don't want that to happen with my guns. Suppose the slide breaks while firing, the whole gun will be f*cked up. Then I can't even use it for display anymore.

very nice gun yellow!

I see you have started with the normal M93 and converted it into a robo gun

I bought myself the robocop gun from KSC and it is a blast indeed! Some power and also, what a nice looking gun huh

BUT I have a problem, while shooting the metal tip at the end of the extended outer barrel broke off
The tip itself is metal with thread inside.
The extended barrel is entirely made from plastic and has plastic thread at the end on wich you screw on the metal tip....
Unfortunatelly it broke off at the plastic thread of the extended part.
So the tip itself can be reused, but the thread at the extended barrel is broken.
So I would have to replace the entire plastic barrel




So my question is, where did you get the parts to make your M93 a robocop gun, since I guess you and I share the same extended barrel?

Also it seems you have a silver inner barrel inside of the outer plastic extended barrel?
That part would be usefull since I suspect the bb's just are releasted free when they leave the barrel but the extend part of my KSC has no barrel inside it and I think the bb's hit the tip on the inside
So a extended barrel is the best I guess


ps: I am also from Belgium, Ghent to be precise, maybe you could help me out?

thx a lot!

Leuk om hier iemand te leren kennen die dezelfde taal babbelt

for the others: nice to know someone here who speaks the same language

In fact I didn't make my Auto 9 with a KSC airsoft Auto 9. I just used the KSC M93R modelgun, and a relatively cheap airsoft version of the Auto 9. I found this at 2dehands.be for a fraction of the price of a KSC one, so why not give it a try?

I really can not compare the KSC one with mine because I have never actually seen one. Mine is completely made of plastic. Isn't it possible with some kind of glue?? I think about black TEC7 or something? Or fixing a big nut on the inside of the barrel extension so that you can screw the tip back in? If you don't want to try it yourself, you may send it to me. I'm willing to give it a try. If we can't fix it, you can still look for another one.

The silver 'barrel' in the barrel extension is a black plastic tube with a piece of silver foil taped around it. It was that way when I bought the gun. If you want you can have it as I removed it to make it a little more realistic.

By the way, I live in Gruitrode, soon moving to Peer.

hey hey, thanks for the clarifications

first of all I've already used superglue to connect the broken plastic part, basically the "broken thread".
But I assume that won't hold up very long as soon as I start shooting it....

Secondly, I already started to sent emails to various online sellers that sell the KSC airsoft gun with the question if they perhaps sell that extended exteriour barrel seperate....

But I haven't thought about that cheap robocop gun solution, I will try to look for something like that, mabye that exterior barrel might fit.
Do you perhaps have more information about that toy gun?

And if I can't find the gun and nobody of the online sellers can help me out, I will sent the barrel to you and you can see what you can do if you like

I'm sorry, but I have also tried to find more info on the internet when I bought it without any succes.
I really can not help you on that.

Maybe you can try modelguncollector. He has a ksc auto 9 for sale on his site, but probably he will not have the barrel extension separately either.

At the moment I am surfing on the Robocop archive forum I think those guys can help me out

http://www.tokyo-model.com.hk/ecshop/goods.php?id=4001

good to know you can buy spare parts when needed (however the kit does cost 110 dollars)



The second time I superglued the tip it holds on, so I will wait to buy the kit, it is not worth it to spend 110 dollars for a entire kit when I only would use the extended barrel.
But I am thinking of buying the M93 version on wich the robo gun is based on and convert it to a robo gun with that kit.
That way I gave a robo gun that can shoot the 3 burst mode (the Auto 9C gun only has single or full auto modes)

Nice! Didn't know that this kit exists. It could have saved me a lot of time!
I payed about the same for the airsoft Auto 9 that I used to make the conversion, and I think this kit is 'plug and play'.
