Thoughts on muzzle device under the silencer…

Does anyone have any thought on if the muzzle device the silencer is mounted to has any effects?

I have a Dead Air Sandman S that I use on multiple rifles that uses the Keymo mount. I’m curious if anyone thinks that having a brake vs. a 3 prong flash hider vs. nothing will have an effect.

I don’t think it matters but this new upper will have an 18” Proof barrel.

Thanks

Eh, I've had over a dozen case head separations. They aren't exciting at all, just a lot of smoke and the next round won't feed because there's still half a case in the chamber. Most of the time you still hit exactly where you were aiming.
Looking at more than the one picture of the piece of brass on its side, yeah that’s more than “just” a case head separation. I mean, look at how much brass flowed to create that ejector mark. I assume that if the barrel is clear and undamaged, and the can is undamaged, that it wasn’t caused by firing into a plugged barrel. But, it was a case rupture, which points to overpressure, somehow…

Rebarreling an AR-15

I've ran bolts, gas tubes/blocks, springs etc. for the life of two barrels multiple times. Sometimes after they've been through two barrels I've thrown them in the parts drawer only to have them morph into a new rifle and keep on trucking.
I've also got one upper receiver that was retired due to wear. Pretty sure I made a post about it here.

Looks like a case head separation. How many firings on that brass? Cut that piece of brass open with a dremel and you will see a stretch line around the base, right where the failure occurred. Now, get a thin piece of wire and curl the end into a J. Cut the short end into a sharp point. Drag it across that line and feel it catch. Do this to the rest of your brass and cull any that you feel catch. Or, trash the lot and get new brass.

I culled this one before it became a problem.

Did you ever come to a definitive answer as to what happened? I know this is an old post but I had something almost identical happen a couple weekends ago. Shook me up so bad I haven’t shot since (and I’m a 2-3 times a week at the range kind of guy). I’ve been reloading for close to a decade and never had any sort of incident, I’m always extremely diligent and double and triple check everything. Anyways, I had shot about half a mag of 220 gr subs and suddenly I was damn near deaf. Took me a few minutes to get my bearings and then I realized my mag was in pieces and my bolt was welded forward. Luckily my can was fine but I couldn’t get the bolt to open. When I got back home and finally got it open (took a ton of beating with a wooden dowel) it looked almost identical to yours). I’m 99.9% sure I didn’t double charge and I’ve had squibs in the past but always realized before shooting again. I’m so consumed by figuring out what happened that I don’t feel comfortable shooting again until I know what caused this.

Edit- Cereal-killer’s issue isn’t a head separation, but I’m leaving the rest here as a reminder to everyone to check your brass…
