The Sons Of Liberty Gun Works Liberty Gas Block .750" delivers a robust, low profile solution for serious AR-15 builds. Machined from heat-treated 4140 steel and finished in a deep black nitride, it offers excellent hardness and corrosion resistance while maintaining a compact footprint that tucks neatly under most free-float handguards. The block is designed to seat against the barrel’s gas journal shoulder for consistent alignment and reliable cycling over high round counts.

This model uses knurled set screws for a secure interface with dimpled barrels and is ready to be pinned if you prefer a permanent installation. With its .750" gas journal sizing, it pairs with the most common AR-15 barrel diameter, making it a straightforward upgrade for new builds or refreshes. The Liberty Gas Block is well suited for duty-style carbines, training rifles, and hard-use range guns where dependable gas delivery is essential, reflecting Sons Of Liberty Gun Works’ reputation for durable, no-nonsense AR components.
