Sounds like you know what you`re doing so have at it, and if you deside it`s not worth the trouble after you have it built then you can sell if to me real cheap and I`ll play with it.
You know what your problems with the action are and they can be over come. I just put a new upper on a Rock River with a 1 in 8 twist and only group I fired with 55 gn. bullets after zeroing was .700 with bullets I had $ 125 US in 2,000 bullets. I shot a .750 group with 50 gn Serria Blitz King bullets which I was tickeled with from an 8 twist. All groups at 100 yrds.
I`m really not a semi-auto fan, more of a built up bolt gun fan. I`ve got acouple of guns shootimg around 1/2 moa at 500 yrds. and think that they will do it at 1,000 if the wind is manageable. The AR is for coyote hunting with dogs, I`ve yet to get a standing shot and the AR lets me keep shooting.
