This is an in-house Geissele 11.5” Nitride, Heavy Profile button barrel with a 1-7 twist rate, made of stainless steel. This package includes our Nitrided Super Gas Block and high-quality Gas Tube. Our barrels are precision machined and button rifled at our state of the art manufacturing facility in North Wales, Pennsylvania, utilizing the highest quality materials available. This is the same barrel featured in our Geissele Duty Uppers.
The Gas Tube comes pre-assembled to the Gas Block. The barrel is pre-dimpled for the Gas Block’s set screws to aid during installation.
If you want to take the extra step to pin/bomb-proof your Gas Block, a roll pin is included as part of the package.
