At this point I am a suppressor addict. So just so flow through feed back, my personal opinion with no data of any sort.
Of the cans I own, the ones that do the best with pushing gas forward.
1) Hux 556
2) Surefire Socom rc3
3) Deadair Sandman with Ebrake
Behind the gun perceived noise by me from quietest to loudest
1) Deadair Sandman with Ebrake
2) Surefire Socom rc3
3) Hux 556
Sturdiest feeling can for heavy use
1) Surefire Socom rc3
2) Deadair Sandman
3) Huxwurx
Flash suppression
1) Surefire = Sandman
3) Hux 556 - it burbs fire every 6 or 7 shots
Cost from most to least
1) Surefire 1700
2) Hux 1100
3) Sandman 800
The easiest to take off after a day of use has been the Sandman, but barely over the Surefire. I have had to take a wrench to the Hux twice.
Honorable mention that I did not include because it is new to me, CGS Helios. It has an attachment like the Ebrake for the Sandman that lets it become a quasi flow through. It reminds me of the SOCOM 2 in its base configuration but better because of the ability to vent more gas forward versus a standard baffle design.
Just to say it, the most versatile is the Sandman because it is a 30 caliber can and I can put it on more rifles vs the 556 specific cans. For 1800 you can effectively have a Hux and Sandman and for 1700 you can have the RC3.
