YHM TURBO-K 556 IN SUBCALIBER ROLE, AS COMPARED TO CGS 22LR SILENCER

CCI "Clean" .22LR subsonic ammunition through both a CGS SIREN silencer and a YHM TURBO-K silencer.

The CGS is a carbon-fiber, dedicated and optimized silencer for .22LR, and sets the bar here, being about as quiet as it gets in the rimfire silencer game.

Whereas the YHM is a 5.56mm silencer, not made or optimized for .22LR. But.. since people are going to run subcaliber through it anyway... how does it sound?
