I am interested in getting a new 308 ar platform. Buds has the new G2 and the old version. the G2 is 1079 and the old version is 979 for the model I am interested in which is the bull barrel 24 in version. Which one is a better buy or which one would you buy? Primary use will be target out to 1000yds. Accuracy is most important. What are the major differences with the G2 model?
