Thanks for the reply and common sense approach. I will definitely give the new barrels a try on the Long Range receiver first. I have had a few occasions where the barrels went onto another receiver like they were hand fitted at the factory! I think that goes to the craftsmanship of the people with LCS that pre-dates the mass computerized CNC machining of interchangeable parts of today. I know I am fortunate to run across those pieces and I think I had one of those rare moments when a project just came together at the right time and price. I hated to see that Long Range in that condition and hopefully it will be back "in full swing" before long. Thanks again for the advice.
