This barrel is an in-house Geissele, 16” Nitride, Heavy Profile button barrel with a 1-7 twist rate. It includes a nitrided Super Gas Block and a high-quality Gas Key. 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 Rifles.
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.
