Mullered mag release

Trying to get this out.  It looks like it's been stripped in the picture, but in reality, it's equally unlikely to have had a head. 

Any idea how get this off?  Gun is a Devgru M16 DG4 A2. 

Tah in advance.

Gently tap a slightly oversized torx bit in to it should probably do it ?

Have tried an assortment of those and no dice.  Surprisingly hard metal for something that scratches so easily. 

Merged edit. 

Figured it out..... 

Bolt catch is held in with a pin, then the mag release needs pushing all the way in so you can unscrew the arm on the other side. 

Guess it's marginally better than a tiny little screw to strip.

That's new (to me anyway), there's always some fecker wanting to reinvent the wheel lol

Now I have the gearbox loose in the reciever, but can I get the bugger out? 

Can I fck. ?

It's the same method as on my Double Eagle M906, so there are similar wheels elsewhere ?

I was fooled by it too, thanks to @Adolf Hamster for pointing out to me how it worked.

Dan, have you tapped out the pin above the trigger?

Real steel style, my GBBR's are the same.

Yes I had for that one.

Just got it out now.  Needed a bit of brute force and ignorance. 

All the gears are fine, so I think the nasty noises were just the engagement height.  

Time to reassemble and battle that damn anti reversal lever. 

I think I kept the shims in the right places.

Indeed; unsurprisingly, real steel M4s do not rely on tiny screws to keep the mag release in place .

You can get a clip that will hold the ARL in place while you reassemble; https://www.ak2m4.co.uk/internal-parts/gearbox-tools/gearbox-installation-hands-kit

Thanks for that.  Next order I place there I'll get those. 

My next learning target is to figure out what I'm doing that results in the gearbox locking when I reassemble it.  I did it to my Specna, now this one. 

Last tech to work on it seems to have done a tidy job.  No excess greese, although the red wire is mighty close to the motor shaft. 

When I can reassemble these things reliably, I might drill the casing and reroute it.  Or perhaps use a slightly thinner guage wire. 

Not sure what mosfet has been fitted either.  Has the label "AAUG09". So will hit Google while I have a relaxing bubble bath ?

That sounds like a Gate serial number. Do you have a photo of the mosfet?
