Default Baffle Strike

I took my new Sako A7 Big Game 7mm Remington Magnum out this morning to sight it in. I got it dialed in at 100 using factory HSM 168 gr Berger VLDs unsuppressed.

I screwed my Silencer Co. Harvester .30 on and fired the first two rounds to check poi shift. Both rounds flew true and went in the same hole. I let the rifle cool and fired the third round. Instantly, I knew something went wrong. It felt like sand hitting me in the face and sounded bad. I looked up and saw my can about 40 yards down range.......

The bullet cleared the blast cone, nicked the first baffle and cut a groove through the rest of them before exiting the end of the suppressor.

Man that really sucks.

I know that some SiCo mounting systems had can launch issues a while back but I thought they had it rectified. I'm not saying that's your probably but I'm definitely leaning in that direction. Send it all back to SiCo with a detailed description as to what happened, hopefully they can make it right.

No. This is a direct thread can. The mount is not the problem.

OP, SilencerCo will take care of you.

Did you check bore alignment before you started shooting? If so, how?

It can also be used with an ASR mount, admittedly I was assuming that's the case here but I could definitely be wrong.

You can replace the direct thread cap with an ASR mount on this can. I agree SilencerCo will get this fixed an back to you within a week or two regardless of what you did wrong . If you did use the ASR mount make sure that goes back to them with the can and I would not re-use the muzzle device.

I did not. I have always fired a round into paper and made sure it flew true then screwed my cans on. This barrel was factory threaded.

Bummer. Yeah you should check that before firing. Can just look down the barrel if that's all you have available. It definitely could have just not been tight enough though. 2 rounds is not enough to loosen a properly tightened dt Harvester.

Regular ASR, no. But Nano-ASR yes, however I've yet to see a single person do that. Plus he has a bolt gun.

Since it was the third suppressed round fired I can assume the threads were concentric to the barrel.

Maybe it came loose just enough to cause it to have a strike. Other than that the only other thing could be something wrong with the load on that one particular round.

He fired 2 rounds to check the alignment, and it was aligned.

OP, that really sucks. SiCo should take care of it no problem.

You can see and feel what I am talking about by closing the locking ring to a point before threading it on the muzzle device. Anyone that shoots the ASR should make absolutely sure that locking ring is fully open when the can bottoms out on the threads and then lock it. You will not have an issue.
It's operator error for sure in most cases.

Right and I didn't mean to imply that any kind of a mounting issue was Silencer Co's fault, I was just trying to point OP in a direction.

Kind of doesn't matter now that it's been verified that the can was directly threaded.

Have you shot with that can on the same host before?

You can go fill out the RMA form on the Website and you will probably need a copy of your form-4 to go along with it. What do the threads on the host look like?

No, this was a brand new Sako.

They are rolled over or flattened on top now. I will take a picture in just a bit and post it.

Default I've seen that happen....

a couple of months back two guys in a row. One was shooting a suppressed AR in .223 I believe. He was sitting two seats over from me and asked if we could make the line cold. I said sure and he walked out about 20 yards and picked his can up. He swore he had it screwed down tight. We didn't see any visible damage to it though.

Second guy was shooting a Ruger Precision in 6.5 Creedmore. I was watching him and the first shot out of the bag he launched his can at least 30 yards down range. Again, we didn't see any visible damage.

Both of these were direct thread cans. Mine is a quick detach and I've always been a little leary of it, but I've not had a single issue. My father nicked the exit of his with a .223, but it didn't blow the can off the rifle.

I had a buddy shoot his silencerco 40yds down range on a baffle strike......not good fellas.

That being said, there is another suppressor manufacturer more notorious for baffle strikes and playing can pick up down range!!

(1) Not relevant, because the OP's direct-thread baffle strike has nothing to do with the QD system that the Plan B was designed to improve.
(2) Not relevant, because the Plan B doesn't even fit OP's can.
(3) There are too many silencer companies whose top staff are not complete penises to give any of your money to Kevin and his ilk.

I wouldn’t buy a single thing from that guy. Biggest jackass in the industry.

OP. Can came loose or bad threads. I’d get the threads checked first. SiCo will take care of you.

Get ahold of Morgan at class 3 machining. Let him check your threads. I know he rethreads a lot of factory threaded barrels do to inconsistency. My concern is why the first 2 were fine. Maybe the threads just weren't cut properly to hold on.

Have it checked by a smith. Rule it out. I’d have him redo it. Not the factory.

Agree, in fact most suppressor companies call out checking factory threaded barrels as they are typically cut very loose.

I had a can launch and I thought I had it tight.
Silencer Co fixed it. They have a one time fix stupid warranty.
I’ve also had a slightly smaller cap which I thought was rated for my caliber. They fixed that too after I explained the issue and the confusion.

It’s a good thing you are ok and nothing serious. Hopefully you will be able to figure out the problem.

Op, can we get a pic of the barrel end and the thread deflection? I am not a Sako expert, but every picture I see of the big game is a very light barrel contour.

Sorry to see you had a baffle strike. Something definitely didn't line up. It could be that the first bullet han a slight strike then another round was fired and the 3 one went askew horribly.


It's not rocket science cutting threads on a barrel. Concentricity is very important between bore an thread tennon. I know how I set up and cut breech/muzzle threads but wonder how its done on a factory barrel on an assembly line CNC. Thinking it was the threads on the Sako barrel.





PS I sent you a 51T mount recently, did that work out for you?

Yes, sir it worked perfect. Sighted that rifle in yesterday as well. I was a little apprehensive shooting my other cans
