Finnish suppressor manufacturer Ase Utra displayed their new training suppressor. It’s a Denny device and can be used for non-blank firing training such as combatives or non-firing rehearsals. This sample has been painted but they are working on a Cerakote version.
If you need a blank firing device, Ase Utra offers this model from their partner Thales which was developed for use with the Austeyr and has been adapted to their muzzle attachment.
