Suppressor help / baffle strikes

[gdun67]

Hey INGO! I'm here looking for some help. I try my best to give all the details that I can...
I have a 450BM manufacturered by bushmaster. It's a 16" mid weight barrel.
I also have a SilencerCo Hybrid 46 suppressor. Paired with a ASR Flash Hider, and a ASR BRAVO quick connect mount. ...
I sighted this gun in, with the suppressor, took 20-30 shots comfortably. Well last Saturday after my morning hunt I took a shot and my suppressor went flying off!!
Weird thing is....my friend has the same setup and his did the same thing!
We both know that our flash hider, Bravo mount, and suppressors were on our guns very tight.

SILENCERCO sent me a email stating that the reason my suppressor flew off is because of a Shoulder Ring?!?!? I have never heard of such a thing. I Googled it and it looks like a "crush washer" but the guy at SilencerCo said it's not a crush washer.

This is the email from SilencerCo....
I asked him to explain a little better for me and he said he couldn't.

Anyone ran into this issue ? Or can point me in the right direction?

The explanation is written out in the email. The barrel has no shoulder. PSA 300blk barrels had this same issue. I think Dead Air makes a collar that goes between what should be the shoulder and the muzzle device. It needs to be used when suppressing the SCAR. Either get that or use another mounting system. I know that Griffin Armament make a Plan A for your suppressor and their muzzle brakes index off the muzzle and not the shoulder

ETA: I see your barrel has an odd threading. He may be correct in stating the best fix is to re-thread it smaller so you have a shoulder. If that can't be done with cutting the barrel then you either have SBR the gun(which I wouldn't do) or buy a 18" or 20" barrel and have it cut down to 16" with 5/8x24 threads

I'm not saying it IS, but it could be user error with that particular mount. There's been more than a few people who have launched their suppressors using that particular mount. I'm pretty sure there's a thread here on ingo...

After reading that thread, and another on a different site, I decided not to even try my ASR and went with the plan A that the previous op mentioned...

Flying Suppressor, Missed Coyote

Flying Suppressor, Missed Coyote Went hunting and missed a coyote because I had a minor baffle strike (several) as my suppressor launched from my rifle. Consulted Silencerco. They said I probably had the locking mechanism partially engaged when I put the can on the rifle and that kept it from...

Damaged Omega from a range....

So I have a buddy (no names as parties are hopefully still working this out) who decided to shoot his SilencerCo Omega at an indoor range. As he was shooting the ASR mount failed and sent the suppressor down range. When he went to tell the employees what happened and to ask for a cease fire to...

Here's what you need OP to convert and still use your existing barrel. This taper brake should index off the muzzle face

If you decide to go that route, GET THAT BRAKE HE SUGGESTED. I've got the older style before that one came out and they require shims.

If your wanting to keep the asr mount these guys might be able to make you a shoulder ring.

Like the other guys mentioned you might as well swap to the plan A system.

 

[sloppyjoe]

I also recommend switching to Griffin Plan A, but I would also use this shoulder ring https://www.kbacustom.com/our-produ...product/34-scar-17s-muzzle-shoulder-ring.html

PMM used to make them for $8, but they are no longer on their site for some reason. Not all Plan A muzzle devices index off the muzzle. I thought the only ones that do are the LH thread AK thread pitches. The rest of my Plan A muzzle devices index off the shoulder including my EZ brakes.

I've got a PM out to Austin at Griffin asking about the indexing. I thought I read in the past that the brakes index on the muzzle.

Even on my AK, I had to buy separate muzzle shims to get the minimalist FH to index off the muzzle before hitting the front sight post based on a recommendation from Austin. Interested to see what Austin says about the EZ brakes.

 

[NyleRN]

Austin said the EZ brake indexes off the shoulder. Then he went on like he usually does giving his over educated scientific response. So I counter asked if he has a taper mount that indexes off the muzzle threaded for 11/16x24. We'll see what he says. I just need a simple yes or no. If yes then which one is it. He always over complicates things. True engineer

This is also why they sell and you should buy and use alignment rods.

I'm very new to the suppressor game. And still new to building ARs. Does someone have a picture of a shoulder on their gun? I watched a video from aero and it showed a shoulder close to the gas block.

From what you guys are suggesting...I should get the Plan A mounting system? And that will take place of my ASR mount ?

 

[NyleRN]

Here's a pic that hopefully helps. The one on the right is what your barrel looks like. You need the one on the left if you're using a muzzle device that snugs up against the shoulder. You can see how more contact surface area there is. If you have a muzzle device that snugs up against the muzzle face then not having a good meaty shoulder doesn't matter.

You can still use the ASR system with a shoulder ring if you want, or you can switch to Plan A. Plan A is shorter, lighter, and does not have a locking ring which reduces the chances of launching your silencer downrange.

Will the 5/8" shoulder ring fit over his 11/16" threads?

 

[Angrysauce]

Just re-barrel it. Get one with 5/8x32 muzzle threads and an ASR muzzle device in the same thread. Sell the old parts to recoup some of the cost.

Good question. The ID isnt specified. OP may want to contact the manufacturer before ordering.

I second this motion ^^^
