i have the classic army m14 EBR scout. this thing is a beast. i have had absolutely zero problems with mine. she looks great and shoots awesome. i haven't opened the mechbox or anything but i've had no reason to as it's been working super good.
i do have to warn you about the weight as this gun is heavy. i'm 6 foot and 220, so it's not a big deal for me. but if you're a smaller guy, it could be tiring to lug around a long and heavy gun.
also, like lurkingknight said, EBRs are not cheap. they'll run you a good penny.
mine in all her glory!
