I was very pleased with this gas block and it looks great - Guntec USA AR-15 Aluminum Rail Height Gas Block

I was very happy with this vas’s block as soon as I opened it. The finish on it looks very good and the overall shape seemed more ascetically pleasing than most of the other gas boocks. It also fit perfectly onto my rifle. Once I got it in place it was easy to align correctly with the rest of the rifle (using a bubble level) it tightend down easily and quickly as well. The rails on it also easily accepted any of the quality stuff I locked into it. The only downside I feel it has is that it only has two tightening screws. I will be taking it to an armorer to drill pin holes in it to ensure a solid hold to the barrel. That was the only reason I didn’t give it 5 stars.
