Yankee Hill Machine Co Low Profile Gas Block, Pinch Screw, .750″, Black
This phosphate-coated steel gas block uses two pinch clamping screws that grip the barrel surface without biting into it, putting less stress on the barrel than a standard set screw mount. Its low profile design clears free-float handguards, letting you run a rifle-length forearm on a carbine-length .750 barrel.

Frequently Asked Questions
What barrel diameter does this gas block fit?
This gas block is bored to .750 inches, fitting the most common AR-15 barrel diameter at the gas block seating area. Always measure your barrel at the gas block location before ordering — common diameters are .750, .875, and .936 inch depending on barrel profile.
What is a pinch screw gas block?
A pinch screw gas block uses screws that clamp around the barrel journal by compressing the gas block body, providing a secure fit without relying solely on set screws pressing against the barrel surface. This design can provide a more uniform clamping force around the barrel. Follow the manufacturer’s torque specifications for proper installation.
How do I install this gas block?
Remove the existing front sight base or gas block, degrease the barrel journal and gas block bore, align the gas port in the block with the gas port in the barrel, and torque the clamp screws to manufacturer specifications. Confirm the gas tube seats and routes correctly to the upper receiver before completing the build.
