The SilencerCo Delta Adapter converts 1/2×28 muzzle threads to an O-ring engagement interface designed for .22 suppressor systems. Its O-ring engagement helps keep muzzle threads clean and prevents the suppressor from working loose during use. The adapter shortens 1/2×28 external threads from 0.6″ to 0.4″ and is offered with a thread protector.
