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

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?

 I think you're right looking at the logo on the back.. Compress_20230305_221856_6640.thumb.jpg.51f8bfc73339c0d7593101d7f913ae0c.jpgCompress_20230305_221856_6846.thumb.jpg.4ad86d641467bb5d3b5ae401a1fa8196.jpg
