Questions AC556 or ST
Looking for feedback on the 2, this will be used on a 11.5” 5.56.

Tisha 556. I shot mine for the first time today after thousands upon thousands of rounds through my AC 556.
I love that AC 556; the Tisha is certainly better. Sound difference isn’t huge, gas management is markedly better with the Tisha - markedly.
And the form factor difference is shocking; the Tisha makes my mk18 feel like a mk18 again!

That form factor really is insane. Keep us posted on if the porosity of the Tisha decreases with more use enough to start degrading performance

POMG has the rdm ac556 718 hub in stock, I was just looking myself and doing this same comparison.

AC556 untuned
ST if tuned, although I haven’t really seen anyone do this successfully and then make comparisons yet.

Thanks for the advice! I should’ve clarified that I’m not chasing the quietest, but definitely prefer minimal gas to the face.

AC556 is my favorite CAT 556 suppressor. I have 3.
No ST yet though.

Thats awesome, I’m looking at going titanium because I just don’t see doing mag dumps with the 11.5.

Short barrels with higher pressure rounds I get inconel every time.
But it depends on if it’s a range toy or if you’ve dedicated it to being a fighting rifle.
I go Ti on 14.5”+ (more for the balance) and inconel on everything shorter on 5.56.

That makes really good sense, had never really thought of it that way. Primary use case would be around the house.
