This is our version of the Nielsen Device, and will mount the Mystic X, Cosmic, Infiniti X or Centurion to a pistol with a tilting or reciprocating barrel. The Booster is the only firearm silencer adapter that will allow your pistol to cycle while shooting suppressed, since it decouples the suppressor from the host weapon during the firing sequence. This nielsen device is backwards compatible with the Mystic and Infiniti silencers as well.

Please do not use this nielsen device on centerfire rifle caliber applications. It will irreparably damage this unit and is not covered under warranty. It is designed for handgun use in lower energy – pistol calibers only.

Should you want to incorporate our nielsen device / booster assembly into your Form 1 silencer build project , we provide a simple info graphic in the link below to assist in fitment of the parts during machining.

Thank you.
