Questions & Answers
Will this gas block work with the KX 14.5 keymod Hand guard and the Prometheus take down system? Expert Answer

The gas block will fit under that handguard and will have no real affect on the DOLOS system as it is mounted on the barrel and does not actually interact with the upper receiver except for where the gas tube meets the receiver.
