I'm looking for a really good AEG that I don't gave to upgrade at all. I would like an assault rifle, non-AK, but beyond that, I'm open to suggestion. M4, g36, Scar, doesn't really matter. Budget is open. I just don't want to spend $1k+ on a systema. What's the top-of-the-line brands? I'm kinda looking at the G&P LMT. Is that good?
