Sons of Liberty Gun Works .750″ V2 Gas Block

Sons of Liberty Gun Works .750″ V2 Gas Block

Ensure flawless gas delivery and maximum reliability on your AR-15 build with the Sons of Liberty Gun Works .750″ V2 Gas Block. Precision-engineered to be one of the highest quality and most dependable gas blocks on the market, the V2 is constructed from industry-leading 4140 heat-treated steel. By matching the thermal expansion properties of standard CrMoV steel barrels, the V2 prevents gas leakage and structural loosening even under extreme firing schedules and high operating temperatures.

The updated V2 design completely eliminates the traditional handguard cap gap, allowing the gas block to seat flush directly against the barrel’s gas journal shoulder for a tighter, more precise fit. Protected by a slick black nitride finish, it includes heavy-duty knurled set screws engineered to bite into barrel dimples and resist backing out under recoil. For duty applications and extreme-use builds, the V2 Gas Block comes pre-machined and ready to be cross-pinned for ultimate security.
