Before joining the upper and lower receivers, make sure the tappet plate has moved all the way to the front. or You will need this.
I’m the kind of customer who sends ROCK-ET questions with nearly every order, and not once have they made me feel like a bother.
They answer with patience and real consideration every time, which is rare for any shop. I recommend them to everyone around me in Korea, and I’m happy to recommend them here too.
As for the Tokyo Marui EVOLT, it’s simply the best electric gun I’ve used for accuracy and sheer fun in the field.
One tip for fellow owners: the tappet plate can occasionally act up. Before joining the upper and lower receivers, make sure the tappet plate has moved all the way to the front. With that one habit, it runs flawlessly.
Great shop, great gun. Highly recommended.
