I have searched all over for info and have not had any luck. The gunplummer review is the only thing out there and it is a bit dated now. I have found a few guys that built guns with the ORF reciever, but none of them had fired many rounds through them to determine the quality of the receiver. I have a great kit to build but I am also unsure about the ORF receiver and the IMI receivers are to costly, (if you can even find one, which I hav'nt). Todd from ORF sells products all the time here in the AK EE. I have been thinking of asking him directly about the problems that were brought to light by the gunplummer reveiw, but its hard to imagine that a vender wood say anything bad about his product. I suspect the ORF is a good receiver, but I also would like more information.
