I took the new LRB rifle out to the range for the first time yesterday. It was very cold with the wind chill factor, so I only shot about 20 rounds at fifty yards to check the functioning. The gun performed without a hitch, and shot a nice group. I definitely believe the gas cylinder shims were a big benefit, as was the NM op rod guide. With so many board members either purchasing LRBs, or contemplating doing so, I was anxious to see how mine would perform. All in all, I was very pleased with the way the rifle turned out, and wouldn't hesitate to purchase another.
