What is a Gas Block?  A Gas Block takes some of the hot gasses from behind the bullet as it comes through the barrel and directs it through the gas tube.  These gasses flow through the gas tube and back to the bolt carrier group which then cycles the action.

Here at Daytona Tactical we carry a wide range of gas blocks in various sizes.  Visit our Gas Blocks section of the online store to pick the right one for your build or upgrade your current one.
