i doubt they will. i'd be very surprised if they did.
as for the red dot. u can get a really decent one for G&G about 80. shop around.
btw, in november, im getting the CA M15A4 CQB. it has the crane stock and the ris. everything ive ever wanted. i thought exactly like you do for a while. then as i got into the game, i realized i need more serious stuff. i used to have a solid stock. that made the rifle rear end heavy which i think is good. but CQ was a problem. im still using the weaver rail, it does its job, but ill need to get the weight of the battery back in the rear. the crane stock is a no compromise solution. Large battery, weight off the front end, and retractability for CQ. the RIS will carry an LCD flashlight on the side and the grip on the bottom. Everything i need is there.
yes itll cost a bit of money. but this hobby is not cheap
