These Griffin Plan A mounts are intended to make your silencer compatible with Griffin TM style muzzle devices. The following is a quick reference for which mount fits which silencer:
- 1.375×24 – This is becoming a more and more universal mount thread pitch for many rifle silencers. Currently, this Plan-A will fit things like the Dead Air Nomad, Silencer Bravo style silencers (omega, hybrid, harvester big bore, etc), YHM Resonator R2, etc.
- 1.125×28 – This thread pitch has long been used in the pistol silencer world. SilencerCo Octanes, Rugged Obsidians, Griffin Revo/Resistance, etc, all run this thread pitch.
- Charlie – This thread pitch is compatible with SilencerCo Saker and Chimera silencers.
