Axial Arms
Reliability when it matters
About Axial Arms
Axial Arms manufactures extremely reliable barrels and gas blocks in the United States. The patented pinned tab gas block uses two cylinder-tipped set screws to create a mechanical interface between the gas block and barrel. This design ensures consistent alignment, allowing gas to cycle the weapon reliably for continued operation. Barrels, gas blocks, and cylinder-tipped set screws are custom manufactured to tolerances equal to or less than 0.002" for uncompromising precision and performance.
Reliability when it matters.
