Thanks for the informations guys... now i have to think about my replica. Is possible to send my lower reciever by certified mail or DHL?? I have family in Montreal, and maybe i an send the loewr reciver part by part. I dont know... is just an a idea. Also i want to keep the m4 body. I have to read very well the "politics" about taking stuff to there.
See you soon!! I will be around asking some questions. Thanks again!
