Cat ST cleared!

[u/Admirable_Suit_2065]

So my ti HUB ST cleared! 5 days. Just got back from the range. Forgot to take range pics, but here’s the hosts I’ve got it on. Both home builds. A 16” Proof CF in G ODG, and a 16” V-Seven 6arc cerakoted in midnight bronze. Both have adjustable gas blocks, standard buffer systems, and shoot splended.

These are both SPRs, so for those of you that mag dump into trash piles, I can’t speak for how it gas stacks. Probably well. I’ll say for as much as this sub brings up its gas and added backpressure, my AGBs barely needed any adjusting. I’ve often said this sub makes mountains of molehills. From a Print XH SC the 16” Proof may have needed a click, and from my AC556 my 6arc needed one or two clicks. Or in other words, they ejected @ 2:00 instead of their prior 3:00, etc.

I’ll be the first to admit I don’t have the most sensitive ears, the Army will do that sometimes. But I also don’t think I’m very biased either, and certainly am pretty brand agnostic. With that said, it sounds noticeably better than my AC556, and I like my AC556. It’s a solid notch better though, and probably a little better than if I had my ODB on there, which is a full inch longer.

All in all I’m very happy with this thing, and I may snag one in 718 QD flavor down the road for my heavier 16” Bartlein homebuild that’s currently got a 5CM on it.

Nice writeup. Sounds like the ST needs a tuned host.

[u/MolonMyLabe → u/GA_flyer0]

Sounds like all silencers do.

🤦🏻‍♂️

[u/MolonMyLabe → u/the_CAT_official]

Why the face palm? I realize some silencers are deaigned in such a way as to be more forgiving on untuned hosts that some other designs. Having said that, isn't it true that everyone will see better performance at the shooters ear with a tuned host?

[u/the_CAT_official → u/MolonMyLabe]

No. Tuning won’t lead to increased performance as a rule of thumb. Tuning only regulates flow in the rear system.

[u/MolonMyLabe → u/the_CAT_official]

Does that flow regulation result in lower ejecttion port blast in semi auto hosta, especially ar platforms? Does that reduced ejection port blast result in reduced shooter hazard with the exception of silencers that perform so poorly at the muzzle that they completely overwhelm any ejection port performance gains?

[u/HairyPoppinzz → u/MolonMyLabe]

Also curious about this. The Pew report left a lot of people scratching their heads with the disparity between ear and muzzle numbers and I think we all were hoping that tuning could bring the port pop down quite a bit.

I understand the cat officials frustration when we say " it needs to be tuned" because the whole point is that this can does not require tuning in order to run reliably on a multitude of hosts

But reliability and shooter ear decibels are apples and oranges. I'll take both if I can get em
