I've handle this peice its detailed well, very much like a TmM rifle but its built for a 10yr old kid. It is approximately the size of a MP5 so it will shoulder on an adult, I'm 6'3 224 lbs, it shoulders but it feels really lightweight. Its sights are adjustable and are useable, with near the same windage and height alignment.
It looks like it has the detachable carry handle but it does not.
It is a nice mini sized replica, some are saying that its 7/8 the size of a regular size M4, but it looks more 1/2 that size. It does shot better the full auto mini electric Uzi. Uzi 80-100 fps, Boys 130-140 fps. Great rifle for a 10yr old kid. Just like the other mini-full size electric guns, you ahve to engage a second swicht on the grip to fire it.
