Gotta say I absolutely love my Battlecomp on my SCAR16. Excellent control without deafening people shooting next next to me.
So when I got my Sig716 and saw it had standard flash suppressor I promptly went out and bought a .308 version for my Sig716 since I was so happy with it on my SCAR.
Well big disappointment. It doesn't do as good a job on the 308 as it does on the .223. Where on my SCAR16 I can easily stay on target even standing and shooting at a human-sized steel target at 300 meters, I have to re-acquire the sight picture on my Sig.
Just for grins I put my PWS from my SCAR17 on it and it actually shot better.
Just my experience, its great on the .223 but is not so good on the .308
