The Maxim Defense Industries CQB Stock Gen 7 for AR-15 is compatible with AR9 platform rifles and PCC's. However, to ensure optimal functionality, you would need to purchase the 7.6oz pistol buffer and spring, which can be found linked below:

Because your AR is chambered in 300 Blackout and using a suppressor, you will need to use at least an H3 buffer to ensure proper functionality and reliability. You can learn more about the correct buffer weight for your build by reading the How to Guide linked below:
