This week end I plan to finish my upper build. I have seen that it is a tight fit to slide the Vltor LPGB in position on the barrel. I am conserned about the "seal" over the barrel gas port to gas block. With the tight fit I thought heating the gas block either in the oven or with a heat gun to expand it to slide it in position on the barrel. This is my first upper build so some good advice would really help. I have checked for similar requests and did not have any luck..
