This rifle length low profile gas system includes a low profile gas block, a standard rifle length gas tube and a roll pin. This assembly attaches to the barrel in place of the standard front sight, and its bolt on design doesn't require the drilling and pinning like a standard front sight.
Barrel size: .750"
Material: Parkerized Steel
Coating: Magnesium Phosphate
Q: How do I install the gas block?
A: Unfortunately we don't offer instructions on how to install the gas block and strongly recommend that it be installed by a gunsmith.
