I had I guess what I’d call a baffle “skim” with my Surefire SOCOM 762-RC on a Springfield M1A Loaded. I ordered a pair of M14 mounts directly from Surefire probably four plus years ago. It took about 9 months for me to get them (they only make them in small runs). I got them mounted upon my pair of Loaded M1A’s about 3.5 years ago. Then I had a heart attack...... A six way bypass later and I couldn’t handle any real recoil due to having my chest cracked. Anyway, I finally got the guts around to shooting the M1A’s again. Took the stainless out before Christmas (weather was remarkably mild till this week) and shot it from the bench at 100.
Recoil was easy to handle with the SOCOM and cycling was smooth. I do have a Sadlak NM spring guide and a TiN coated NM piston in the rifle. My shots weren’t even hitting the paper and the rifle was zeroed previously. After some more shooting at 25 I’m way off. I investigate and I see some nicks on the endcap and a slight “brush” on the last three baffles. 
I removed the flash hider today cause I was thinking maybe there was something on the muzzle tipping the flash hider. The M14 mount uses small shims right off the muzzle as there is no barrel shoulder. When I took it off the muzzle was fine. Just a minor amount of carbon around the sides from this range trip. Looked down in the muzzle device and noticed something amiss. The shim was broken. 
I’ve got a call into Surefire support and we’ll see what they say. This was the first outing with this muzzle device and can on this rifle. I’ve had this can on my AR10 as well as several AR15 SBR’s with no issues. Rifle at the range before shooting: 
After in the truck: 
I was shooting PRVI M80 147gr FMJ. Nothing special. |

That sucks. Maybe get a alignment rod to check if the mount makes the can unaligned.
Edit: I’m sure it’s the mount or the the barrel isn’t threaded concentric. It’s just a gut feeling. |

I spoke with Surefire today. Sent them all the info and pictures. There is rumbling about sending the can, mount, and of course shim in. Guess we’ll see.

I just use the cheapo pointer torque wrench. Its surprising how little effort it takes to get inbetween the recommended 20 -30 ft/lbs

Good luck OP. But from the pics it doesn't look serious, just looks like the end cap was kissed. How bad do the baffles look?
Edit: re-read the OP. |

Nah, it's not too serious. Just pissed as it's a pretty freaking expensive can. Can is on it's way back to Surefire as we speak.

Called Surefire today. It's in "inspection" stage. I should hear something back from them in about a week or so. Fingers crossed......

I had them fix a 300SPS with an off-center baffle last year. Sent if off in late April, didn’t get it back till August
Best of luck |

They contacted me today. Stated “no defect in material and workmanship” in the suppressor. Said it was a concentricity issue. I called back in and left a voicemail. I agreed it wasn’t a problem with the can. The concentricity problem was caused by the shim (supplied with the mount) that broke. It’s not like I explained all that in the ticket or anything. I hope I can get it straightened out. Worst case I’ll just pay to have it fixed. Way too expensive of a can to not repair it.
I’ll tell you this, when I get it all fixed and back, I’m not indexing the mount. No shims for the M14 for me. With the way the mount goes over the barrel you can’t see what’s going on. Way too easy apparently to have it messed up with a shim in there. |

That kind of sucks. I don’t think I’d even bother with a repair if it costs anything out of pocket for you. It’s unlikely to affect anything running as is (assuming you fix the concentricity issue). I’ve had a nasty chunk out of my end cap on a yhm titanium can for like a year, no issues. They told me they’d repair it for free and sent me an RMA, I’ve just not found it necessary.

Damn, and the shim was theirs that THEY provided with THEIR mount no? Any chance that the shim didn't seat all the way correctly and part of it ended up in front of the bore?

I would NOT pay that much for a repair. Just take it to a good smith and have him open up the hole.

You should contemplate having the barrel chopped and threaded for a custom adapter, this is what I did and couldn't be happier. The barrel male thread will be something odd (doesn't matter), but the adapter will have a proper shoulder and standard 5/8x24 thread. The adapter is threaded concentric to the bore while installed on the rifle to ensure you won't have baffle strikes. It decreased the barrel length to just short of the factory grooves, which makes it a little handier with the can installed. I had Chris at Aquila Firearms work on mine but I would also trust Morgan at Class III Machining to do the work.
I see you are not using an adjustable gas plug but I have found it to work well with reducing blowback and bolt force. I also am using the gas lock front sight as I'm using open sights, not optics. Gas Plug Purchased from Midway USA: Schuster M1A Adjustable Gas Plug Steel Parkerized Gas Lock Purchased from No Kick: SEI-2013SEI M1A Gas Lock with Sight Dovetail for 18" barrels |

As much as I would like to own a Surefire Mini, this type of customer service will prevents me from ever making that purchase. This is horrible in contrast to what SilencerCo, DeadAir, YHM, Rugged & Griffin have shown!

After I spoke directly to the rep they are going to try and replicate it in house with an M14 they have along with my can, mount, and broken shim to see if there is an alignment issue. They said they'd get back to me today or tomorrow. They originally suggested me shipping my rifle to them and I said no way am I sending my Springfield M1A to California.......

He did have to talk to management to get it sorted. I'm pretty happy with that! |

I would call right now, and tell them I'm sending the stripped barreled receiver, so they can check everything, and do whatever is needed to get it right.
Then, if there's a problem, it's all on them. As the suppressor was sent to them in California, also sending an easily replaceable rifle to them wouldn't worry me. If absolutely necessary, have any competent gunsmith put an index line on the barreled action (for easy reassembly), pull the barrel, and just send that. |

What did the alignment rod tell you after installing the new mount?
If the OD of their shim is small enough to let it slide over far enough to obstruct the bore, they should really look at using a different shim. Even if slid all the way to one side or the other, it shouldn't be able to obstruct the bore. |

I dropped them into the mount and made sure they were flat against the mount shoulder, then lowered the rifle into the mount. When I put it together before I stacked the shims on the muzzle and screwed the mount down. I think one of the shims caught and bent when I was putting it together before, hence it probably folding over the muzzle and breaking. When I eyeballed it at the range prior to shooting I saw no bore obstruction though. I checked my AR10 and it was dead nuts in the middle. I also checked some other cans and rifles I've been using over the years. Rem AAC-SD with a TBAC CB9 was to my eyeball perfectly centered. AAC MPW9 with an ASR mounted Omega was pretty darn close. Just barely off center. |
