I'll admit this is more of rant than anything else. I've been having issues with feeding on the magazines with my Echo 1 Timberwolf, so I've been working on fixing that. So when I was testing it, all of sudden, the outer barrel shoots out and lands on the floor. Color me surprised when that happened.
Here for your amusement is a picture of the outer barrel pieces.
Needless to say, after looking online a little bit, I found that this is not uncommon with the Echo 1 Timberwolf (or the WE 17 on which it's based).
Combine this with the magazine feed issues I've had with 3 different magazines, I'd have to advise anyone considering buying this to stay clear.
As an additional note, I can not in good faith recommend the KWA ATP pistols if someone was looking for a Glock style pistol. While KWA tries to market the ATP as a training tool, personal experience in a training environment with new KWA ATPs, makes the ATP a no go. Too many failures (Not to mention the way they hide the gas fill point).
