I picked up a nice Nagoya 5th series at the show this weekend and found that the inside of the barrel had been opened up and threaded. I don't have a way to measure what the size of the bore is for sure, but with a 1/32 tape, it seems to be 11/32 in diameter. The base of the cut is smooth and looks slightly tapered into the chrome finish on the bore. The threads look quite fine and are in good shape === as they don't appear to have any fouling in them from shooting. It has a nice deep mum and all numbers but the bolt match with the receiver being 79112. Anyone tell me why the barrel would be threaded or for what device would fit it? I'm also looking to replace the bolt with one numbered 112 = anyone might have one of them? Oh, the threaded portion appears to be about 1/2" deep and then about 1/8" unthreaded to the base, before the rifling starts. Seems to be very well done and not the job of "Bubba"! Any help would be appreciated. Thanks Sorry about the quality of pics = I tried about 6 times and these were the best two.
