dboys hk416 fire selector help

captain wow

Hey there folks. looking fir a bit of help with the fire selector on my 416.
The selector has always been loose and wobbly and any kind of movement or recoil will knock it out of position. I have a brand new replacement ready to go but I can't access the screw inside the receiver to remove it. I've tried to remove the dummy plate on the opposite side to fain access but that is firmly set in place and anything I've tried to remove it has failed and scratched the paint. short of drilling through the dummy plate I can't think of a way to get through there.
Any suggestions would be helpful! I've reshimmed and rewired the gear box with no drama but this has me stumped! it's annoying the hell out of me!

you can use a standard allen key either, as long as it's big enough it should have a large enough angle. Take the gearbox out and put the short end of the allen key on the back of the dummy plate, then use the long end to push against the other side of the receiver (the angle in the allen key should be big enough to hit the inside of the other side of the receiver), the angle of the allen key along with the longer end will act like a sort of fulcrum and should pop it right out

I can throw up a picture if it will help

As per the info in post #2, it's a phillips head screw / bolt

Yeah i know but that's to remove the selector plate itself, this method I use removes the other side, then allows you to put a standard screwdriver through the hole where the dummy plate was removed and remove the selector plate this way.
Using the specialised screwdriver may be easier but it requires the tool itself, I personally don't own so you had to come up with a different method

As I was confused, maybe a pic would help us all and I'm always happy to discover other methods of Airsoft DIY

Here's what it should look like
NOTE: This is an old receiver and i just put all the parts in it myself but it should give ya's an idea

The get an allen key, something like this:

Then place it into the receiver with the short end against the dummy plate, opposite the selector switch:

Apply some pressure by pressing against the side of the receiver with the selector switch on it, and it should pop out, leaving you with this:

The screw is missing as I just got old parts like i said but you get the idea, put a standard screwdriver through that hole and voula, done

why thank you sir Had the same problem when I started working on AEG's. everytime someone came in with a loose selector switch I used to look at it thinking how did they do that . had to improvise. Hope it helps the Captain Wow, and anyone else really

Hey thanks everybody for your ideas and suggestions I'm gonna have another go at it tomorrow evening!
now that the removal is sorted how does one go about replacing it? is some sort of adhesive required or do you just have to persuade back into place with a few taps of something?

just hit is a few time with a rubber hammer or I usually use the back of a rubberised grip of a screwdriver
