Slightly off topic, but non the less informative.
I have used PointAct several times, each time I had my order shipped out within 24-48 hours. To this day (roughly 4 orders with them) I have had no RMAs needed.
Note on the D-boys m4.
The metal is good, not to cheesy feeling. Their crane stocks are a joke, don't bother to use one. I taped my battery to the outside of the stock and found it to work much better. The plastic is ok quality, not to bad.
If you have any specific questions let me know, I own a couple D-boys aegs.
