The .750-inch bore diameter of this gas block matches the most common barrel outer diameter at the gas block seating area on standard AR-15 barrels — confirm your barrel’s outer diameter at the gas port before ordering, as barrels are also available in .625, .750, and .936 inch diameters depending on the barrel profile. Low profile gas blocks are designed to sit below the inner diameter of a free-float handguard, allowing a full-length free-float rail or handguard to extend over the gas block without obstruction. Unlike a standard front sight base gas block, a low profile gas block has no iron sight tower, making it compatible with most modern free-float handguard systems. Gas blocks are typically secured to the barrel by set screws that engage dimples drilled in the barrel, or by a clamp or taper pin arrangement depending on the design. Verify the barrel has the appropriate set screw dimples or that the gas block’s attachment method is compatible with your specific barrel before installation. The gas block must be positioned so the gas port in the block aligns precisely with the gas port in the barrel for reliable cycling of the action.

Frequently Asked Questions
What does “.750” mean on this gas block?
The .750-inch specification refers to the inner bore diameter of the gas block — the opening that fits around the barrel’s outer diameter at the gas block seating area. A .750″ gas block fits barrels with a .750″ outside diameter at the gas port, which is the most common barrel diameter for standard government-profile, M4, and heavy-profile AR-15 barrels. Confirm your barrel’s outer diameter at the gas port before ordering, as lighter pencil-profile barrels may use .625″ and heavy bull barrels may use .936″.
What is a low profile gas block?
A low profile gas block has no iron sight tower — it sits below the inner diameter of a free-float handguard, allowing the handguard to extend forward over the gas block without obstruction. This design is required for most free-float handguard installations on modern AR-15 builds where a low profile block is needed to clear the handguard’s inner diameter.
How is a low profile gas block secured to the barrel?
Most low profile gas blocks are secured by set screws that thread into the gas block body and engage dimples drilled in the barrel surface, or by a clamp arrangement. Confirm that your barrel has the appropriate set screw dimples machined into it, or that the gas block’s attachment method is compatible with your barrel before installation.
