Not trying to resurrect an old thread, but I thought this might belong here. I had a chance to test out two different muzzle devices side by side. I have the PWS Triad on my 308Mega, and a SLR mini-comp on my 308TNArms-Aero. This is not remotely scientific but it answered some questions for me. I shot them side-by-side, five rounds at a time, same KAC sights on each rifle, the Syrac gas blocks adjusted just enough to reliably function, same reloads throughout the "test" (42.8 grains Match Rifle, Sierra 168 BTHP, LC cases, Win LR primers). Five rounds one, five rounds the other, repeat. Over 60 rounds this way. I can say the SLR really let me get back on target quicker. It is a really fine little device. In fairness, the PWS is billed first as a flash hider with some compensating abilities, and it did a good job, but the SLR was really so much better, It's an amazing little device. I may have to get another. Anyone want a Triad, cheap?
