This screws onto the barrel inside the shroud and allows the fitting of after market silencers to Zbroia Rifles.
Rifles that are made before December 2017 require a M12 thread whereas post 2017 require a ½ inch UNF. If you have any questions regarding which model you require don't hesitate to call us on 01263 731585 and ask for Chris R. Alternatively email him at : firstname.lastname@example.org
Please Note : As this Moderator insert is classed as a "Component part", it must be delivered and signed for face to face. This will incur the same delivery charge as regular silencers so we recommend ordering both together to save on postage.
