I can't speak for the manufacturer as a whole, and I know that a lot of cheep Chinese full metal bodies are questionable at best, but I have one that works like a champ, the metal body is surprisingly sturdy and the gearbox has some sturdy construction, metal bushings and spring guide and such. One version has a two piece metal RIS that works great. Just thought I'd throw that in
I'll second this. My AGM M4 has been my loaner rifle for years. Its been battered and abused and keeps on working. The only problem it has every had was semi-auto wearing out. I've loved it a lot more than did my G&G sportline MP5 (combat machine) and my friend's G&G combat machine. And it has a beefy high torque motor with thick wiring unlike G&G's combat machine motors which all, frankly, suck. Same goes for G&G's wiring.
As for the cheap metal body everybody hates on, I like it. Beats the living hell out of plastic. It just feels right.
