5/8″-24 thread adapter for K31-XXI Blitz
CHF 40.00 (TVA incl.)
The adaptor goes in the K31-XXI base (instead of the actual brake), and allows mounting of any accessories (muzzle brakes, flash hiders, silencers) for the standard 5/8″-24 thread.
Machined Chro-Moly steel, mil-spec manganese phosphate coating.
IMPORTANT: when mounting long accessories (e.g. silencers) it is absolutely paramount to perform a visual check of concentricity of the complete assembly, by looking through the barrel from the chamber side. Do not use your firearm if the accessory is not 100% concentric with the barrel. (By the way, the advice goes for mounting of any silencer on any carbine.)
