You can't beat the price of this gas block. I installed it on my build and I am very happy with it. I crushed the roll pin that came with the kit when I was trying to taper it to start easier into the block (oops). I had two extra pins, so I used one of them and all went smoothly. The block fir the barrel nicely. The gas flow is as needed for the build, as it recharges the BCG effectively. I couldn't be happier with this gas block, especially for the price!
