Dirty Bird .625 Low Profile Steel Gas Block - Black Nitride

Don't let the simplicity of a gas block's function fool you, it is possible to make a bad one. Gas blocks must handle high gas pressures and extreme heat so using sub-par materials is out of the question. They also need to be machined to exacting standards, otherwise you run the risk of driving yourself bat-shit crazy because every roll pin you try to use ends up mushroomed and bent all to hell or worse yet, causes excessive leaks or blockages in the gas system. The Dirty Bird Industries .625 Low Profile Steel Gas Block is the answer to all of these potential problems.
