I am very impressed with the KAC CRS2. I had low expectations since KAC cans have a rep of not sounding great for the money. That said, I thought the CRS2 did an incredible job taming my Colt 10.3 SBR. The insane concussion was completely deleted, and muzzle flash wasn’t detectable to my eyes (late afternoon/early evening outdoor range). My Colt is also pretty overgassed (fixed gas, 6940 series), and I didnt see a change in the ejection pattern with the can on or off. I think the best part though is the QDC mounting system. It is extremely fast, smooth, and solid; IMO hands down the best suppressor QD system I have ever personally used. Overall I am completely satisfied with my CRS2, just wish KAC had more mount options (a brake would be nice that didnt cost $380+ and is impossible to find lol, or different thread pitches for irregular 5.56 pattern guns).
Also props to the Rooftop team for the quick shipping and quality service.

Sol is the man. Answered several questions I had and shipped ultra fast as usual.
Crs2 is phenomenal. Lock up is super tight, sits really close to the rail on my lmt shovelnose. Good sound suppression, zero gas back.
