Jeweling on the bolt is very thin and it's being worn isn't at all necessarily a prediction of how much the gun has been shot...it is rather an indication of how much the bolt has been activated and some folks play with their bolt a lot....some even lap the lugs by cycling the bolt thousands of times.

I had one of those guns and they are quite hard to find....Mine was wonderfully accurate! I'll bet yours is too and just needs glass bedding or barrel floating..... A worn out .223 is not a common item....however it's good to check for throat erosion!

If you're not interested in it I'd be interested.....please let me know where it is if you don't want it!
