Hello guys, I recently picked up a WE M14. Fully functioning. I have a scope and scope rail system along with a preinstalled 6.01mm. It also has the 500 FPS nozzle installed.
This is for DMR so the ROF does not matter to me. Currently my upgrade list is:
RA-Tech Hop Up Rubber
RA-Tech Trigger Assembly
What else would be needed?

If you plan on using it at mia events it will have to be semi only modded.

How does one modify a gbbr to semi auto?

I think the trigger set and hop up are pretty much the only things you'll need. You've already got the tight bore so unless you've got to have all steel, that's really all you need. Only thing I may recommend is the new aluminum nozzle for the m14. I just installed the SCAR version for my buddy and they are very nice, I'll be getting one for my WE M4 I like them so much. Much more consistent fps than the old version. Plus they allow you to change the fps in case you want to go to a field with different fps limits and such. Not necessary, but might be something you'd be interested in.
Edit to answer your question: basically remove the selector switch.

Unless you're feeling particularly ambitious and want to experiment, putting the selector on semi-auto and removing it is pretty much it.

Yep, there is a simple bar to remove in order to disengage full auto. Also, the stock trigger assy is pretty garbage and most break after a couple thousand shots. RA-Tech makes a complete trigger assy for $200

I would highly recommend an external air rig if you plan to build a DMR. Gas-in-mag GBBR consistency is fairly poor and not stable enough for real accuracy work.
GBBR's require their actions to be lubricated and they run off of a lubricated gas. That lubricant is going to be blown off the seals and deposited on the hop rubber and in the barrel as you fire it. This will be especially noticeable on humid days (this is Michigan) where the propane does not fully evaporate and leaves a film over parts in the gas route. I lightly lube my action and seals and run dry propane. This helps to cut down on the amount of stuff blown into the barrel. I still clean it at lunch and wipe out a decent amount. Just the nature of the machine. While my accuracy is still acceptable from 100-150' it is hardly DMR like. You can avoid most of this by running HPA or regulated CO2. For these reasons, I would stay far far away from green gas. WAY too much lube.
I have found the NPAS to be less stable than the stock valve. I see FPS creep in two platforms (WE 416 and L85). Your best bet would be to play around with an external rig and various valve springs until you found a balance of pressure range vs operating consistency.
Gas-in-mag rifles are really fun. They just aren't consistent enough for long range accuracy work. Sitting in the shade vs sitting in the sun can cause different FPS output. While it is often repeated that FPS doesn't matter, the acceleration of the projectile is in fact a big part of the equation. While 10 FPS between two different rifles may not matter much, 10 FPS between two shots will matter. Further more, if you are playing on a cooler day you will use more gas. That means your first shot could be 525 but your tenth shot could be 465. 60 FPS between shots matters. Especially if you are running heavy ammo like .36-.43 (which you should). If you want some things to ponder over, go look around for discussions of spring powered vs gas-in-mag sniper rifles. You will come across many external rigs.
None of this would matter as much if you were just running and gunning with it in semi auto (full auto consistency is infinitely worse). But if you want an actual DMR, it's going to matter.
