As with the 5.56mm version, the Integra 300 BLK has several unique features that contribute to its design. An 11-inch, 1:8 twist, barrel provides the basic foundation for the Integra 300 BLK. A shroud for the G-CORE baffle permanently attaches to the barrel, making the overall length 16.1 inches. That makes the Integra 300 BLK a one-tax stamp rifle.

The 300 BLK Gemtech Integra Upper has an MSRP of $1,999.
