I am thinking about buying a OOW reciever, but I notice they say it is over 1 milimeter thick. will I have the same trouble that comes with global oversize recievers?? I am not going to mill my trunions even if I have to ues vulcans. I realy want to go with a better name reciever but milling the trunions is not an option. can some guys that have actualy built on OOW recievers PLEASE post in and advise me on the good , the bad, and the ugly of OOW.
