The Dead Air Silencers SIG Mosquito Thread Adapter 1/2×28 is a SIG Mosquito thread adapter from Dead Air Silencers, built to 1/2×28 spec. Dead Air Silencers machines it (Dead Air Silencers part no. DA420) 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 anyone running a suppressor setup where the small parts matter as much as the can itself.

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 SIG Sauer Mosquito .22 LR 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 SIG Sauer Mosquito .22 LR 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.
