I've already sent this can in once because of baffle and end strikes while using it on my 9mm handguns. Relegated it to 3lug using their 3 lug adaptor and had a strike today while using it on my AK-V. 3 Lug muzzle device is a Hansohn Brothers seated on the barrel shoulder, not the gas block. Can, including mount is all Rugged.
Guess I will be paying to ship it back to them to have everything replaced again. Perhaps they need to open up the baffles a little or figure something else out with this thing. Love the can, suppresses very well. But I'm now not sure what gun I will ever use it on.     UPDATE So my can is in the mail and I sent a message to Rugged because their online form doesn't give the most room to type everything. I explained that after my can was returned to them the first time for baffle/end cap strikes I switched to the Griffin EZ Lok system but had since relegated this can to 3 lug (using their 3 lug adaptor). This strike happened with 3 lug. I also asked about 147gr ammo as it seems most of what I have read online is about heavier subs. I told them I love the way the can suppresses, along with using SC made guns, ammo, and cans, and wanted to make sure I could get the full potential from the can. The response from Travis was: "Hi d16man, The EZ locking system does not work with our suppressors and can cause issues which it sounds like what happened in this situation." SMDH. I don't even think he read my email. I just sent a response saying that yes, EZ Lok does work with their cans and that this baffle strike was because of their 3 lug system. I also asked again about 147gr ammo, maybe this time he will read my email and actually respond to my questions.Update 2 Travis is emailing me a bunch which I appreciate. He has asked for pics of thr Tri lug but even when I said it indexed off the shoulder and not the gas block (this is a PSA AK-V) he questioned what I told him. I can understand that and I sent him more pics. He also said 147 gr ammo was not an issue because that is what they use to test with. |

That’s crazy. I’ve never seen an obsidian with an end cap strike before

I’ve heard AK’s are notorious for not having concentric (is that the right word) muzzle threads.

Could you be having an ammo related issue? Were you using the same ammo when you had the strike last time? |

This time 147gr aac. As for concentricity, the HB tri lug is on the barrel shoulder, not the gas block. I fear there is something design wise with these cans due to the crazy amount of end cap and baffle strikes. It sounds great, but wondering if thr holes need to be slightly larger. |

This is the third time I've heard about AAC ammo causing baffle strikes.
I won't be buying any of their ammo, just not worth the risk. |

Aac has had a sub par rep with their 300blk destroying cans. I provide a bunch of examples here.
Although that's the wrong caliber. So I don't necessarily suspect it to be the ammo right away. I've seen more messed up obsidians than I have all other pistol cans combined. Was your end cap loose? I see that happen fairly often where I work at. For rugged cans, the Obsidian 9 only seems to suffer from these reocurring issues, so I wouldn't compare anything else to it. Did you diagnose what messed up the can the first time? Did you ever check alignment? I didn't see this stuff when I briefly read through. |

Big question is the bullet type People don’t really differentiate between AAC ammo with another manufacturers bullet vs the in-house AAC bullet. Like ive heard of issues with their 55gr FMJ 5.56 but nothing with the 5.56 with Hornady or Sierra bullets. I won a case of their 77gr SMK ammo in a match, NOT their 77gr OTM, and it’s been great |

With an obsidian you keep the clips aligned. To my engineer brain I could see that being an issue because it's going to change the linear pressure on that side of the can. |

This user had the same problems. After three trips back to rugged, Rugged says it’s not fixable. Poor manufacturing, or a design flaw.

Rugged has probably sold thousands upon thousands of Obsidian silencers.
*The below is for those not familiar with direct thread silencers, not saying the below is what the issue is with op's silencer but a general fyi* Ammo, alignment, an uneven barrel shoulder or thread pitch all play a roll and there could be a number of issues on why baffle and end cap strikes happen. Alignment probably being the number 1 reason. Its well know that you should always check and tighten your silencer after every magazine if using direct thread if not more often. If not tight, they can loosen up even after a couple rounds and cause strikes. Failure to check often will almost always guarantee a baffle or end cap strike. Its a good habit to check it after every magazine even if using a 3 lug, ez-lok or cam-lok.* I have an Obsidian45 and have used it direct thread, 3 lug and EZ-Lok with a variety of ammunition never a problem. *knock on wood* The dumbest thing i did with my Obsidian was when I changed it from short to full configuration, I forgot to put the end cap back on and blew all the baffles out and scattered them down my range. I found them all and went over them with a fine tooth comb. Reassembled it and shot it and it worked just like before i had my brain fart. My opinion is that the ez-lok will alleviate most if not all the issues people have with baffle and end cap strikes. Its also known that AAC ammo has caused issues as well. This specific silencer could have a manufacturing defect or it could be something else. Sucks your having this issue op, hope you get it figured out. You could always put a 45 end cap on it and try it that way as well. |

Subsonic vs supers creating not enough pressure and leading to baffle and end cap strikes......again, my engineer brain going. That makes the can a bad design if it can't run subs, which is a big part of having a can. |

But there is a known issue with using AAC ammo and having baffle strikes, enough thats theres two people in this very thread that say will never use AAC ammo in their firearms. Regarding the end cap, I confused your post with the other person saying they got an end cap strike. I think its obvious that a different end cap won't stop a baffle strike. That suggestion was direct towards them, not you. |

That comment was direct towards them, not you. Gotcha. On Saturday I shot AAC 45 through a can and in the past have used 300blk AAC with no issues. Difference is those are thread on cans. As foe Rugged, based on a previous thread referenced as well as others on this forum and other online sources, I think it is too tight of tolerances/design flaw, especially given the Obsidian 45 doesn't seem to have as high of instances of baffle strikes. I also shot an Obsidian 45 on Sat but it was on a Henry .44mag fixed without a Neilson device. |

Quote HistoryOriginally Posted By d16man: This is a known issue mainly with an Obsidian 9....it seems the 45s are GTG. And it isn't a known AAC issue. After reading the thread above, and more online, I am leaning towards any 147gr ammo being an issue. The thread above used 5 different kinds of ammo, none AAC, and he sent his can back 3 time. And a 45 end cap won't stop a baffle strike.... What’s the bore diameter on the 9mm obsidian baffles and end cap? -Is it at least 0.415”? -It looks like there’s enough material there to bore it out farther…. I had 2 different. .308 cans from another mfg… one shot great, the other had huge POI shifts and occasional flyers. After I repainted it I noticed the bullets were rubbing the pain off of the inside of the endcap bore. I measured the two and one can had .360 bore, the problem can had .348 bore. After boring it out to .360 it shoots great w/o any issues. |

I'd suggest checking booster housing ID and piston flange diameter, as well as condition of the o-ring in the retainer.
BPISTIN, as we call it, which is rugged, silencerco, YHM, TBAC, of course our stuff, and others, should have a piston flange diameter of .992-.995" and a booster housing bore of .996-.998". If the booster bore is large, the piston small, the o-ring flattened or any combination of those, strikes are likely. |

I haven't shot it much since getting it back from Rugged after my first baffle strike. It had their 3lug adaptor installed at the time of this baffle strike. |

It had their 3lug adaptor installed at the time of this baffle strike. That removes the retainer o-ring and piston from the equation, but not the booster housing bore, since the Rugged 3 lug uses it. And I can't tell you what spec is for the rugged 3 lug bushing, but the flange should be a pretty tight fit to the booster housing bore, and the bushing bore should not have much wiggle on the 3 lug barrel/adapter The SilencerCo AC2447 and Kaw Valley 3 lug adapters are self contained if you find you have a booster housing or 3 lug part issue |

Can went back today. I sent rugged a long email and asked specifically about 147gr bullets since everything I have read on here, reddit, SH, etc....seem to point to 147 gr being a part of the issue. I haven't sat down and done any of the math on pressure changes with weight and powder. Even my engineer brain wants to do that but I don't have the time with work. I asked if they could open the baffles and endcap (I doubt they will) or at least give me some better info. I prefer 147s to maximize using a suppressor.

I’ve frankly been underwhelmed by Rugged products. They’ve got a good warranty and their centerfire rifle cans should be nearly indestructible, but outside of that they’re a solid meh, IMO. I say that owning 4x Rugged cans.
I do have an Obsidian 9 and haven’t had any baffle strike issues so far with about 750-1000 rounds through it, almost all Speer Lawman 147s. Hosts have been exclusively a G17 and an Sig M18. Funnily enough, almost all using EZ-LOK.  Anyways, I’m now patiently watching to see if I should start paying closer attention to it. I haven’t had the can apart in at least a couple hundred rounds. |

The 9mm end cap on my Obsidian 45 looks like a disaster. Probably 5-6 end cap strikes while using their direct thread mount on a Lage Manufacturing M11. I finally switched to an hanson brothers trilug hoping to solve my end cap strikes.

I'm wondering if he was thinking Cam Lok...seems I remember Griffin didn't make cam lok for Obsidians when I switched. |

I'm now using the Kaw Valley Precision Mach 3 lug wit HB trilugs. Hopefully I don't have any more but the hit yours took wouldn't even register on my end cap anymore. I tried to have it serviced once by Rugged but they never responded to my service request form and I never followed up. |

If you want his email I will forward it to you. As far as I am concerned, Rugged's CS so far has been top notch. |

I think I read somewhere here about the same and Rugged only recommending using the 9mm end cap on the O45 in the short configuration. I haven’t read it directly from them though unless I missed it in their instruction booklet. |
