OK so I took some pictures. A star on the top of the receiver, a star on the extractor but cannot see an actual star on the bolt body? The bolt number matches, although this could be force matched? Is this a mk1* bolt? All of the parts seem to be marked with an R (seemingly for Remington). The barrel seems to have this R too- which marks seem to be Hebrew? As far as the step between barrel and receiver goes- I tried to find images of this online- some seemed to have it and some did not, but that could also be the quality of the images. I do not mind if it is a mashup of a gun, I just want to know if it is safe to shoot? I ordered an extra front sight assembly just to compare the current one to as well. My ammunition came in, but I have yet to shoot it. Should I try and have a gunsmith align the barrel? Thanks for all of your input guys!
