With an adjustable gas block, you can easily fine-tune performance for either subsonic or supersonic loads, making it ideal for suppressed or unsuppressed setups.Whether you're upgrading or starting fresh, the DISSENT .300 BLK Upper Group delivers compact firepower with precision and reliability built in.
