A simple but effective way of HPA tapping your G&G LevAR.
Simply unscrew your entire gas valve and collar assembly by turning clockwise and install the HPA tap by turning anti clockwise.
The threads on the resevoir are extremely thin and can be easily cross-threaded or damaged - take extreme care and go slow when installing!
I have included a tiny printed key to assist in removing the standard collar assembly, I would highly recommend using a proper gas key to remove but I've included these to be used in a pinch.
