So it is evident that the trigger and hammer are smaller than the WE stock counterpart. Although this difference is significant, it doesn't affect the function of the gun (not yet at least). HOWEVER, the reason why my selector lever was unable to securely push down the sear was because the lever and the selector nub (Part #99) had some rotational movements. Here is an image of Part #99:

Notice how its flat on one side right? This part inserts firmly into the stock selector lever to prevent any wobbles. However, the RATech selector lever hole is not the same as the stock counterpart as shown below. Stock on the left, RATech on the right.

Because the RATech version is not flat at the top, there is a bit of wobble when Part #99 is installed in the hole. The amount of wobble is enough for the selector plate to be out of position when switching to full auto (especially with recoil), which in turn renders the full auto to be disabled (since the selector cant push down the sear anymore). The stock selector plate however, has a cut out hole that perfectly fits Part #99, and thus, minimal wobble if any. As such, any movements on the fire selector will directly translate to movement on the selector lever.

So to solve this issue, what I did was that when i installed Part #99 into the selector lever, i placed the lever on full auto so I can see its position relative to the sear. I ensured that the selector lever can actually engage the sear before fastening the grub screw into place. Also, when you do install the grub screw, add a drop of blue loctite so the grub screw holds in place. Also, make sure that Part #99 is firmly pressed against the receiver in order that it inserts firmly in the selector lever before the grub screw is fastened. Anyways, im going to be using a RS fire selector with Part #99 when i RS my gun, hope it will work well.

Im not sure why RATech decided to manufacture a steel counterpart of the selector lever as there is minimum wear on this part. In my opinion, I think a steel version of Part #87 is much more important since it is constantly being impacted by the bolt in able to release the hammer forward.

Here is a video of the gun fixed on full auto:
