Hausken Barrel Nut 1/2x20 UNF Moderator Adaptor

• Genuine Hausken barrel nut for the Hausken moderator conversion system
• 1/2x20 UNF thread — one of the most common UK rifle muzzle threads
• Adapts Hausken's standard 18x1mm moderator thread to fit a 1/2x20 UNF barrel
• Allows one Hausken moderator to be swapped between rifles with different thread pitches
• Precision-made to thread directly onto a correctly cut 1/2x20 UNF muzzle
• Must be matched to the correct barrel thread — confirm your rifle's muzzle spec before ordering
• Compact, low-maintenance component with no moving parts to service

This Hausken barrel nut is the 1/2x20 UNF thread adaptor from Hausken's conversion system for their sound moderators. Hausken moderators are made in Norway from hard-anodised aluminium and are fitted as standard with an 18x1mm thread; a barrel nut is what adapts that fitting to match a specific rifle's muzzle thread. Fit this 1/2x20 UNF nut and the moderator threads straight onto a barrel cut to that common UK muzzle pitch, giving a secure, repeatable mount without needing the barrel rethreaded. It's a simple, purpose-made part rather than a universal fitting, so it should only be used with the corresponding Hausken moderator and a barrel correctly threaded to 1/2x20 UNF. For stalkers and rifle shooters already running a Hausken moderator, it's a straightforward way to move the same can between rifles with different thread specifications, or to fit a new barrel without buying a whole new moderator.
