Okay...this is kind of a thread revival but here goes,
Dear god this body has given me (welll....more so the guy workin on it rahter than me) so many problems.
Besides the spelling mistakes, mag well being too tight and the buffer tube not fitting on other problems have arose. (yes im aware the last 2 problems are an easy fix)
Now there have been minimal problems that are more or less easily fixable. But heres one thats gonna sting.
There is a big problem with the body when you put the outer barrel on and the inner in the hop up does not line up with the nozzle. If this does not line up properly you will break nozzles and cylinder heads all the time.
SOoooo I guess the final word is this. Be prepared to do a LOT of fixing/dremeling and the likes.
