That's what I thought, but POF uppers ship with Krink brakes and I've seen some AR15 pictures of people with LW uppers with Krink brakes, and the LW rifle I handled at SHOT had a Krink brake on it, so, who knows.
The KX3 is good because on real rifles, it directs all flash and noise forward of the shooter. I dunno, until I read otherwise, I'm gonna keep it on there (and it's like, the best airsoft suppressor).
I don't think I'll EVER have any NODs...but I could borrow an IWAL-2 and put it inside my current PEQ and, well, I can order replica Troy BUIS
Nah, I like my rifle now it is now.
