The barrel's pistol length gas system provides optimal reliability with subsonic ammunition while suppressed, and supersonic ammunition while unsuppressed. While supersonic ammunition may also function with a sound suppressor installed, subsonic ammunition fired without a sound suppressor may cause cycling problems.
