The first one I got wasnt staked on the second bolt for the gas key. Plus the hex was stripped out. Had to pay shipping to return item. Not primarys fault, but for a higher end bcg, fail zero's quality control should be better, especially on something so obvious. The replacement was acceptable, but the staking on the same hex bolt was minimal. Not blown away by it so far though. It looks pretty. At least its made in the US.
