5.56 7.5" DI pistol with 9" 556 Evo rail and HERA linear comp done...

I'm having a hard time believing this - I've shot 7.5" AR pistols with A2s and the fireball and concussion was ridiculous. My Hera Comp (gen 1) significantly cuts down on both. I don't see how a PWS Triad could do a better job. It's basically just another three-prong flash-hider. Not that I'm doubting you, as everyone's experiences will differ based upon many variables, but I did try a Wilson Accu-Tac on one 7.5" and it was barely better than the birdcage. With my Hera, I noticed the difference immediately. It was much more pleasurable to shoot and definitely sent more sound and blast downrange. I'm scratching my head on this one.

I'm with you. I was VERY surprised, and I cannot explain it. It is consistent with other reports, though.

I shoot a ton with various configurations and muzzle devices, including 3-gun competition, so I'm pretty aware. Like I said, I was so impressed with the Triad, that I skipped even trying the Hera or the CQB. I'd say the concussion from the 7.5" barrel with Triad is about like shooting my 16" barrel with a BattleComp. I fully expected the big ass fireballs like my buddies' 7.5", but mine has very little flash, and I shoot mostly either Federal 223 or XM193. My guess is that whatever they were able to accomplish to eliminate flash also disperses the gas in such a way as to minimize concussion.

The only other factor is that my upper is piston driven and not DI. I don't think that would have a huge impact on perceived muzzle blast, but it might have some.

So you're having no cycling issues with your setup? That's pretty good news. What made you decide on a 7.5 vs 10.5? With that brake on there it is darn near the same size.

Well I like PWS stuff and the Triad has always intrigued me so it looks like I'm going to have to pick one up.

Absolutely none. It's eaten everything from Fiocchi 40gr V-Max .223 to mk262 with nary a hiccup from day one. Mostly I bought the 7.5" because I wanted a range toy that could double as a "PDW" if needed. I'm not going to lie - it's the only AR I've built based on looks instead of functionality, although it has that in spades and is a very nice weapon. I just wanted a neat looking pistol. That's all. With the Shockwave Blade and Samson hand stop on it, it looks sweet now. I have plenty of BCMs and DDs for if the SHTF. This build was all pleasure.

Nothing wrong with an aesthetics based build as long as it works.
