CAA does not provide dimensions for their MCK Glass Breaker. I'd recommend reaching out to them directly for more information.

The CAA MCK Glass Breaker fits the Micro Roni 3rd Generation, the Gen 1 MCK (you need to remove the flashlight plug/flashlight/laser. On Gen2 MCKs, there is no need to do this), MCKSIG models, the glass breaker works with a flashlight/plug installed, M&P MCKs, the flashlight must be removed before installing a glass breaker. The flashlight plug does not need to be removed, MCK21, the flashlight and/or plug needs to be removed prior to installing the glass breaker. Does not fit the 29/30 model of MCK.

The manufacturer does not provide the specific thread pitch of this CAA MCK Glass Breaker. It will only work on CAA micro conversion kits with the included 2-piece plastic adapter that fits over the barrel shroud on the conversion kit.
