Same with the Ti. I haven't gotten around to weighing our 718 stuff but the Ti ODB I have was 195 grams. That's 6.878oz. Weight listed on their site is 8.8oz. Did they forget to shake out the let over ti powder?

The 2nd odb ti that is my co workers weighs in at 10 grams heavier than mine (i still have not shot mine). This was shot at our suppressor event a week or two ago and probably has 200ish rounds of subs through it. Here's the problem: we never weighed his brand new.

Nice. Useful, decent looking, competitive prices.

Any plans to stock their suppressors?

My backorder for a CAT ODB 718 HUB from SS was filled 6/17, back order was from 4/24

Must have been a small batch that came in because I didn't see them come back in stock at SS

Does anyone have first hand reports or time behind the Alleycat Ti cans? ODB or WB, don't really care.

I want to toss one of these on an SBR and the listed temp threshold (800F) would allow for fairly hard use...but I can't shake the conventional wisdom "Ti = no bueno for hard use".

To be clear I wouldn't be dumping magazines into the berm or FA. But it needs to survive bill drills and whatnot.

EDIT: I'm wrong, read posts below

If I recall correctly, someone on Reddit said it took just 45/50 rounds at a steady, fast pace to reach the 800deg temp limit, but then it cooled fairly quickly after that

In my opinion, the only time I need to shoot that much *might be once in a while at a competition. I can structure my drills to not reach that. So to me, the weight savings are worth the limitation. Compare that to your training schedule and see if it works or not

When I think "hard use" I'm thinking like... Firefights/mag dumps, which isn't what I'm doing so I don't worry about it

The titanium ones hit their heat limit in maybe 10-15 rounds. Mr Recce, Alabama Arsenal, and another channel that escapes my memory right now have videos on it. No idea about the inconel.

They heat up so fast that it has even made me wonder how the Mob would handle full auto.

well i just got the permission slip for my ODB ti. too bad my foot is going to be fucked up for another week or so.

ive already shot it outdoors, so i know its quiet (spoiler alert, its quieter than a hyperion on a rattler); but we shot it when it was really windy.

ill try to get a video when i go out.

I've got both the titanium and Inconel Alley Cat's.  The Inconel is on a 12" LMT. and the Ti is on an 11.5" MCX.  My thermometer gun is already packed in my range bag, but it's going to be July, before I get to the range and collect some data.  

Piece of Mind has posted some stuff that leads me to believe the Ti versions can take plenty of shooting.  They have a Ti Alley Cat with over 6K rounds now.  They claim mostly demo shoot time, and the blast baffle looks pretty good.

Appreciate the feedback from everyone. It's a tough call and I'd happily get an inconcel Alleycat if they were around.

I did several drills in a row yesterday with my OCM5 (also a Ti baffle can) on a 12" bbl. Not intentionally abusive but a rapid rate of fire with no meaningful time to cool down. I saw a max temp of 650F after 20ish rounds. Different can, hardly scientific...But I think the Alleycat Ti can handle "normal" aggressive firing so long as it doesn't stray into abusive.

ETA: disregard what I just said about the OCM5. I'm an idiot

OCM5 doesn’t have Ti baffles, but a Ti outer tube chassis around a stainless core. It’s also much heavier, roughly twice the mass. With that said, I’m sure the Ti CAT would be fine with light to moderate volume use. They claim it’s good for up to 30 rounds per minute in the manual.

With the shorter wait times and the Ti being more available than the Inconel, I guess we’ll hear about it soon if it doesn’t work out. Hopefully it’ll be fine. The mount is a stainless brake, right? Like with the Trash Panda?

Long day at the office, you are absolutely correct.

I think I'm gonna send it. $1,100 is expensive but not eye watering for a can. Worst case, I'll have a really quiet can for the long(er) rigs that don't get beat on. The flash hider is steel I believe.

I wonder why the Ti Alley Cat has a higher temp rating than some other Ti CAT cans?

“TITANIUM Ti6AI4V
C.A.T Old Dirty Bastard (ODB) Titanium 7.62x39mm suppressors are limited to barrel lengths of 10" or longer. Full Auto or High Rates of Fire (HRF) (greater than 30 rounds per minute) are expressly discouraged, unless in life threatening self-defense situations, as the ODB Titanium is a lightweight, high performance suppressor dedicated to Low Rates of Fire (LRF), and the user should not exceed a maximum service temperature of approximately 650°F (343°C). Once this temperature threshold is reached, the suppressor should be allowed to cool down. Titanium Ti6AI4V has inherent material properties which give the material a lower heat conductivity rating, and the suppressor is susceptible to particle erosion and melting past this temperature limit. If the user notices discoloration on the exterior discontinue use and allow it to cool down. Do not dip the suppressor in water in an attempt to cool it down.
C.A.T recommends ODB Titanium users invest in an infrared thermometer and create their own platform specific firing schedule, based on ammunition and barrel length. It is recommended to create this firing schedule by shooting five round groups, with one second intervals between rounds, then testing the temperature of the suppressor up to 550°F (288°C). At this operating temperature, the user should record the amount of time until the suppressor returns to 150°F (65°C). This would become the baseline firing schedule based on the user’s platform and ammunition type.”

Could be differences in thickness at key locations that heat up first. If the metal gets weaker with heat, then making it much stronger at room temp by beefing it up adds safety margin. Also adds some heat capacity. Trade off with additive manufacturing is some added cost as well as weight.

Back ordered a JL 718 hub 6-12-24, will update when ships.

I got cold feet on using Ti hard. Found an inconcel Alley Cat 556, just waiting on the Form 3. More to come once I get my hands on it.

because theres more meat inside the can. alleycat stuff is marketed towards LEO/MIL.

Just picked up my WB 718 hub mount.

Bare core weighs 15.3 oz. 2.5 oz over advertised max weight.

I think it's in the outside wall.  In other pics you can see the ridges from the spiral venting. Not visible on my can.

Not sure how I feel about the added weight. Have not had a chance to shoot it yet. So no comment on back pressure or sound. Should be an upgrade for both over the saker it's replacing.




The SR22 A1 is 2.8 without end cap. 3 oz with it included. Definitely happy with this can.

Took my CAT WB 718( 556 Midlength) and ODB 718( 30cal midlength meant for intermediate cartridges)home today. I was curious if these were over bored at all so I did a drill but test to get a rough idea.

Tl;dr they're not over bored

The WB would fit a .2812 through the flash hider but a .2969 did not fit. In the back a  .26 did not fit but a .25 did

Odb .3593 did fit .375 did not fit, both ends.

Test isn't perfect but it gives enough info to say these aren't massively over bored.



Also tossed my scope in it but did see anything interesting because it's only a front facing cam and the head size is like .3, doesn't leave much room to look around.

I don’t know how I missed this, but CAT added a section to their website discussing their different technologies and describing how they work. Kind of interesting stuff.

Link

Has anyone heard directly from CAT that the ODB is rated for any .30 cal cartridges larger than the 7.62x39 ( e.g. .308 win, .30-06, .300 WM)?

I can't remember the last time I saw a .30 cal can that wasn't rated for at least .308, but a poster on the hide put the question to CAT and in their response they seemed to indicate that it is a niche can made for the cartridges they state. Looking through their kind of crappy website, and sure enough they only mention 7.62x39 and even refer to it as a 7.62x39 can.

Don't know how I missed that bit of info until recently, I was thinking about getting one to use on my SFAR, but it doesn't sound like it rated for .308 use.

Says it has technologies that help stabilize projectiles…..

I did a 3 mag dump with the odb on a 13 inch 308 and it held up fine.

Cat seems to have a hard on for the idea of cartridge specific Silencers. Like the ODB being a 7.62x39/300blk supers can, people are going to use that on 308 etc but in CATs mind it's not optimized for that.

I can see some logic in that. They wouldn’t be the first company to see things that way.

I'm guessing you have the 718 version.  How did it sound on 308?  Have any comparisons to other silencers?

So far ill say the ODB sounds a little better than my Flow 762 ti on the scar but also had a little more back pressure. It was very close.

But the ODB does sound a decent bit better than the flow on 300blk subs and 5.56. All I've really done so far.

The ODB is a phenomenal can.    Went shooting this weekend with a friend and we used it on multiple platforms and calibers.    I am very impressed.

What chamberings did you try it on this weekend?

Yep. It's the most impressive 30 cal can I've shot to date for 300blk

It truly is in a class of its own.

WB 718 that lives on a 11.5 spear rental. I think it's gained 20 to 30 grams. I have no idea on round count but it's been on the gun since the last week of May. It probably gets rented every day atleast once.

We soaked it in the breakthrough cleaner for 12 to 18ish hours. I wanted a baseline with no ultrasonic and it didn't seem to do much. So I had my gunsmith toss it in the ultrasonic for an hour or two right as I left today. I have to work tomorrow so if I have time I'll check the weight.

Cat continues to deliver.



Edit:
It's been in the ultrasonic for a couple of hours.

What's the difference between the WB and the Alley Cat cans?

I believe they stated something like outer wall thickness and coating since the Alley Cat is considered the LEO model. Same internals from what I understand.

Thanks for that. I'll do some more research since the Alley Cats are in stock and WBs aren't.

Thicker construction. One more baffle. And only offered in their QD system.

Anyone tried a MOB on an HK SP5?

I haven't seen much love for the JL - any reason for that?

@Mesooohoppy where does it say the Alley Cat has an extra baffle compared to the WB?

My cgs rep.

So if it has an extra baffle then shouldn't it be better than the regular WB? Quiter/blowback.

Anyone know of a place to get a WB 718 hub at?

Not a SP5 yet but it's phenomenal on my MPX-K.

Alleycat 5.56 Inconcel blast baffle for anyone interested. I'll weigh it shortly, it's a chonk

ETA 18.8oz without mount

Thanks....let me know if you hear anything about one on the HK

Weird it's list at 16.6 0z

That is stupid heavy.  All of the CAT cans I have seen in person are all weighing in at 1-2 oz heavier than advertised.  I’d love to know why, but everyone seems to not care.  I’d just like to know why they’re so far off advertised weights.  I don’t think that’s a good sign of quality manufacturing, but again, no one I talk to seems to care they can’t adhere to their own specs.

Edit to clarify all of the ones I referencing have been inconel.  I’ve seen quite a few people say their TI ones are actually lighter than advertised.  Just odd.

My odb ti was a couple of ounces lighter than what was advertised on their site. My buddies was the same thing as well.

Not sure how or what they're using to get these numbers, but they definitely don't match what people have in their hands.

One opinion and one fact that I learned about 20 minutes ago

Opinion: I'm used to an RC2 and YHM Turbo 1 that are both 19+ OZ after many thousands of rounds. I don't like extra weight but it's acceptable to me.

Fact: Per CAT my particular can is actually a .mil-specific version of the Alleycat that was accidentally shipped out in "normal" Alleycat and WB718 packaging. They had a small run with this mishap and mine falls in that group based on serial # confirmation. The extra weight is mostly in the blast baffle, which is visibly thicker than say a WB. Per them it's not a dramatic change vs the Alleycat line, which is already beefed up...but this is literally the toughest can they make for anyone. A happy accident in my opinion
