Hausken sound moderators are manufactured in Norway in hard-anodised, high quality aluminium for durability. Each moderator has two main parts. The baffles are machined from a solid aluminium bolt, 35mm, 45mm, 55mm or 70mm in diameter. Each moderator is fitted with an 18x1mm thread but, using the unique Hausken barrel nut conversion system, the thread is adapted to suit your rifle.
