Built like a tank
This is one of the best built AR 5.56 receivers on market today. It is very robust, the gas piston assembly. V it does not have any thin washers acting like a gas stop like most others. These are known to break or wear out over time/round count. Causing fail to eject issues. This has a solid block of steel in their place, the multi washer gas stop. There are many little improvements over typical mil spec AR upper receiver. It all adds up to being one of the strongest upper receiver you can buy. Typically, A91's don't use or need a forward assist and that tells you of it's track record.
