browningautorifleicon,

No, that's not far. The question is the barrels that were used on your builds. If you did not rebarrel, then I assume you were using barreled receivers and rifles that needed restoration or a stock set. You would have seen several different barrels during your work.

Like I said, It doesn't matter to me if an individual rebuilt it or a factory did. The question is the barrel's origins compared to the origins of the receiver. If this barrel is not original to the receiver (which I don't think it is), and not the type that was used on factory upgrades or FTRs, then someone else did it. Someone else who may have used a defective or rejected barrel.

As a shooter and small time collector, thats a big problem. Now maybe you see the why and what in my research.

Thanks
