Suppressors Ultra 5 question

[TimK]

Ray or Zac,

I'm considering a 5" ultra. It will spend most of it's life on an AR in 5.56. What, if any, difference in sound suppression should I expect between the .308 and 6.5 versions? If it matters, I'll be running the flash hider mount, not the brake.

If you've ever wondered if there is a market for a 5" Ultra in .223, there is at least one guy who'd buy one if you offered it.

Love my other 4 TBAC cans...

Hi,

You can expect the 6.5 version to be 2-3 dB quieter when metered at the muzzle.

Love my ultra5 .30 cal. It goes between everything from my .308 to my x47 match rifle and 5.56 guns. Need to buy a couple more

That 5 incher is the sleeper can they sell that not everyone is familiar with. I love it and it's perfect for lots of uses, from PDW's and SBR's to longer, full power rifles. Really no reason to not use a can when it only adds four inches to the rifle. If that. Technically it's also a suppressor and not a moderator. Many short cans are just moderators, they're treated the same by NFA, but a moderator isn't "hearing safe" whereas a suppressor is. The Ultra 5 is just barely hearing safe, and thus a suppressor. When used with .300BLK subs it really shines, but works well with supers too.

IME, using longer cans now, generally the difference firing a 5.56 through a 7.62 can isn't really "how loud compared to..." it's more a question of tonality. The difference, if 2dB or less, may not be noticeable but even if it's 3dB that can sound like less due to the tone. Generally the larger bore cans have a deeper tone and the smaller bore a higher tone but less dB's, comparatively. Some people prefer 5.56 through 7.62, just sounds better to them despite being technically louder.

Yeah, the 5" Ultra is actually one of my more favored cans. It does a lot for that tiny size and it weighs nothing. If you are using a 9" on various rifles then this also makes a nice addition.

Sorry to reply to such an old thread, but I was having a discussion with someone about wear on the Ti cans.

Do you happen to have any footage or photos of what the cans look like at the end of high round counts?

 

[Zak Smith]

I can probably dig out the Dominus-SR's we put through the 10 (or more) Surge cycles That's a high round count considering the firing schedule. Let me see what I can find.

In general though, it's round count at high temperatures that causes erosion.

A 17-4 brake will be ruined in roughly 5-7 SURGE cycles.

If you're not shooting surge style cycles or firing rates how do the TI baffles hold up against the incolnel alternatives?

Just curious, have one dominus-k already and another one still in jail, thank you for the superb product!

Titanium is a lot tougher than people think. It does surprisingly well with abraision. The surge cycles actually show how tough titanium can be if the suppressor is designed properly. In 10 cycles of the surge where we destroy 2 muzzle brakes the suppressor itself has enough erosion to be 3 dB louder than a brand new suppressor. Depending on your ears 3 dB is about the threshold for someone to be able to tell a difference in sound signature between 2 suppressors.

I don't have data comparing erosion between an inconel suppressor vs ti suppressor of idential design. I can say however that I've never had or seen an SR muzzle brake need replaced from erosion from normal shooting and the surge cycle goes a brake every 4 cycles. So if the suppressor is only giving up 3 dB after 10 cycles that destroys 2 muzzle brakes you shouldn't see any performance loss after a substantial amount of normal shooting.

Thanks for info!
