The Dead Air Silencers FN Five-seveN Thread Adapter 1/2×28 is a FN Five-seveN thread adapter from Dead Air Silencers, built to 1/2×28 spec. Dead Air Silencers machines it (Dead Air Silencers part no. DA422) to factory tolerances rather than as a generic aftermarket stand-in. It is a host-specific thread adapter that converts this pistol’s factory barrel thread to the pattern a suppressor mount requires. Without the correct adapter, a suppressor built for a common thread pitch will not index onto a host with a proprietary or less common thread, and this part bridges that gap. It is a practical pickup for a range gun, hunting rig, or working suppressor setup that needs the correct hardware to run right.

Key Specifications

• 1/2×28 thread pattern is the exact host thread this part indexes onto, so it seats flush against the barrel shoulder.
• the FN Five-seveN pistol is the specific host this part is machined to fit.

Frequently Asked Questions

What is this thread adapter machined for? It is cut specifically for the FN Five-seveN pistol, converting the factory barrel thread to 1/2×28 so a common suppressor mount can index onto it.

Why does this pistol need a special thread adapter? Some factory barrels use a proprietary or less common thread pitch that most suppressor mounts are not cut for, and this adapter converts that thread to a common pattern.
