This is the direct thread mount for the SEG12. Our SEG12 uses the standard 1.375-24 main thread at the back of the suppressor allowing for different mounting options. These direct thread chokes use the M22-0.75 external thread. The direct thread choke requires the M22-0.75 M22 Direct Thread Adapter for the back of the SEG12 suppressor, available HERE. It is also available with items in this listing as a bundle.
Also in this listing is the KSG M22 mount that replaces the lock nut on the KSG series of shotguns. Like the choke mounts, this mount uses the external M22-0.75 thread.
Please note: all that is needed for the SEG12 to mount to SAIGA / VEPR type shotguns with M22-0.75 external threads is the M22 Direct Thread Adapter
