I honestly can't recall what gears were put in mine, but probably steel Ultimates. I'd personally advise that you get it upgraded and stick with it. It'll be the only AEG you'll ever need and it's certainly the only one I've had for years now. Excellent indoors and out.

As advised in the Evo Owner's Group, contact JD today. They'll replace it or repair it under warranty. Just make sure that you were using the recommended power of battery, or it could invalidate your warranty. Almost every Evo suffers from weak gears, but once upgraded, they're fantastic and reliable. My gen.1 first batch Evo shat its gearbox a few months into ownership. I had it repaired by Landwarrior, but paid to have it upgraded at the same time and I've had no issues with it since and that was years ago. Best AEG I've ever owned in 10 years, Marui's included.
