Very small & light weight
I'm giving it 4 stars instead of 5 because the gas tube roll pin hole did not line up with the gas tube. The roll pin started but when it reached the other side it hit the inside of the gas block and stopped. The pin bent and had to be removed. After further inspection I discovered that the roll pin hole in the gas block was drilled at a slight downward angle missing the center line. The gas tube's hole was drilled perfectly through the center. To get the roll pin installed I started a new pin to line up one side of the gas block's hole with the gas tube's. Then on the other side had to run a drill down the gas block's hole to drill out the of the gas tube so the pin would not hit and pass all the way through the gas block.
