Someone made Halo's assault rifle in real life

The detail is pretty impressive.

Gamers can be passionate about their hobby, and now a fan of the Halo series has made his own version of the iconic assault rifle, which can be seen in action here. It even has a working ammo counter, so the attention to detail is definitely there, and that's why a lot of people are excited in the comments section.

What weapon should be next?

Thanks, Reddit.
