They are regulated and taxed ( and rather expensive) devices to reduce muzzle blast (not truly silenced). They are not illegal, and very desireable for hunting as most hunters prefer unmuffled ears in the field in order to hear game, or while dove-hunting to hear the call-outs of other hunters. But thus results in potentially damaging noise levels.

Noise limitation devices are Required in some European countries during big game hunts so as not to disturb other animals and nearby hunters.
These countries often have stricter gun controls than the U.S.

Unlike the nonsense from Hollywood they diminish, not silence the blast.

UGH.
