SilencerCo Scythe Ti failures

[Bluefish]

Mine was in the 19,000 range

So definitely a more recent production. Maybe why the failure was further down the stack? Supposedly there are two grades of Ti for the baffles. Would be interesting to know where the change occurs and if that’s where they fail.

What's it gonna take for Silencerco to do a recall? Seems pretty obvious that the welds are too weak under average usage.

Put 7-8 different make/models of cans through a stress eval today…. Guess which can was the only one to have structural failure?

Looking forward to reading it, but I bet I know the punchline already…

Still struggling to reconcile all the failures in this thread failures with people like @Ryan Avery who have done everything possible to make their can blow up without success. Seems like there’s just no margin for error on the welds and for those that get a bad weld, it’s only a matter of time regardless of caliber.

If a person chose to do their own “stress eval” and their scythe (or other can) survived, would that provide any reassurance?

I’ve tried to make mine fail and havn’t been able to. That dosent mean it won’t but I’ve gotten it hot enough to melt a cover to it and nothing happened.

No. There is no safety margin with the scythe.

This is paper mâché-

I think my OCL Titanium rimfire suppressor is thicker/heavier than that…

What kind of firing schedule?

 

[Formidilosus]

What kind of firing schedule?

The first question is: if it structurally failed in the same manner as they all are failing; and yet no other can structurally failed… does the firing schedule matter?

I’m not defending it. I’m just wondering what the firing schedule was out of curiosity

 

[packgoatguy]

nevermind. mine is all better now. a little tape, and it's good as new.

I understand, I meant it more for others reading.

90 rounds near cyclic, 5.56mm, 10.5” barrel. However it failed before 90 rounds.

Have any of the cans that were sent back failed a 2nd time? Possibly at a different weld. This may have been mentioned earlier and I missed it.

There is a 2nd failure option in the poll up top.

 

[mtwarden]

Looks like four folks have experienced a second failure

This is not a defense of the Scythe, but do you think that the uncorking pressure might be higher for 5.56 than for some other cartridges?

Again not defending it but that seems to be beyond what the intended use case is for it. It’s not rated for full auto so I’m not surprised that 3 mags of cyclic killed it. Looking forward to reading the eval to see how long it survived

The real issue with this kind of test seems to me to be that titanium can get weakened by going above 800 degrees, but that doesn’t mean that it will fail right then. A can might survive a 90-round magazine dump and then fail on the fifth round some other day. But I think Form knows that better than I do.

There are numerous failures in this thread where the failure occurs after what I consider a prolonged period of regular but gentle use and it comes apart before the tenth shot of that particular day. That’s what worries me most about the Scythe. I can put a couple of hundred rounds of a relatively mild cartridge through it (e.g. 6.5mm Grendel) and not have any issues, but then it can let go on me on round 205 or 220. And Murphy’s law says that won’t be at the range doing normal practice, but the instant I let someone else use it or take a shot at a buck.

As the titanium, lightweight can game continues to progress, I suspect there will be others that fail similar tests. Essentially the companies are just taking performance/ weight savings too close to the edge of failure. IF the Scythes were only failing on "near cyclic 90 rd dumps," that would not bother me at all. My use case would never approach that threshold. The problem with the Scythe is, some are failing with 20 rds, some a 100, some havn't failed with 1000's. Big cartridges, small cartridges, short shot strings, long shot strings.

A hunting, ultra lite, titanium can, should never see "near cyclic" 30, 60 or 90 rd mag dumps. If this is your intended use, there are better options out there.

Does anyone know the rd count / rate of fire, at which titanium starts to approach that 800* mark? Seems like that would important info to avoid damaging or weakening the can. I US and Airlock put that in their info, but I would guess the average user, has no idea where that threshold is approached.

I found this thread while I was waiting for my approval so when I got mine I tried my best to baby it. Never shot it more than a 5 shot string before cooling it with a battery powered Milwaukee fan . Only positive thing is when it blew up my poa / poi wasn’t affected. Wonder if that’s the case with others who’s failed ?

I agree with all of this. There definitely seem to be some “random” failures that point to questionable design/qc/both(?)

But this stress test sounds more like intentional destructive testing than anything else. It’s well beyond the intended use case of the scythe

For me, personally, I don’t care about the POI if I end up out in the field with a broken collarbone or orbital bone.
