Suppressor comparison


Recommended Posts

Suppressor testing GIS vs ATec smg on my Sig MPX 9mm. 9mm is quite a dirty round in terms of adding carbon to a suppressor. Short version…… the ATec is cleaner, much easier to clean and shorter. A-Tec on the bottom and GIS on the top. ATec is 42mm diameter and GIS 35mm diameter.

Noise reduction is similar to my ears but the shot timer will not record the ATec at all and sometimes the GIS with the same ammunition (subsonic). I have two timers so I will set one up to work with subsonic.
