Of all my cans, this is the only one I've had a strike.

During a conjugal visit I had an endcap strike with my Obsidian45 shooting low-powered supersonic 45-70 rounds, however, I did not have Teflon tape on the direct thread adapter like I should have.

I really only grazed the endcap but it did give me something to consider moving forward. The baffles were good to go.

I'm watching this thread closely.

Everyone I personally know who owns an Obsidian 9, myself included, has had at minimum an endcap strike and a few with baffle strikes. I know more people who have Sierra 5's who've had fewer issues than an Obsidian 9. Great sounding can though.

I have a thousand plus of 9mm and .38 spl. through mine with no strikes, direct thread.

I have estimated 500 plus through it with a Rugged piston and had one pretty bad endcap strike.  Before I switched to EZ-LOK,  I would only shoot it in the short (and wet) configuration to minimize the chances of another strike.

LOL, and indeed.  Certainly someone has figured out what the flaw is.  I just wish that person would tell us.

Well, shouldn’t be an issue of a narrow bore then… i think bullet dia +0.060 is pretty much the standard there….

I often wonder if the threads on the rugged pistons/accessories are cut on the looser side of tolerances, causing issues with staying tight and causing baffle strikes.

The obsidian is basically the same thing as a Silencerco octane and the octane has been around for 10 years, with practically zero issues with end cap/baffle strikes.

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.

Well that’s good to know! I hadn’t heard that and I’ve used the 9mm cap on the Obsidian 45 in long cfg w/o issues *yet* but only shooting 300 blk through it… I’ve only shot 9mm through with the 45 cap on it so far.



I’ve course it would be a bit of a stretch to say I “read” the manual… I did open it once though!

That's not what happened. Rugged never said they couldn't fix it.

Yes, I am aware that they stay aligned on Obsidian cans.  I also know other companies have them opposing. What I am wondering is, since there are a lot of reports of endcap strikes on obsidian’s, and the one pictured above shows the strike in line with the notches: are the majority of end cap strikes on obsidian’s in line with the notches? If so, than the alignment may be a factor.

That I don't know.  Would be interesting data for sure.


More data.  Mine from this last weekend.  Not sure what gun I was using it on when it happened since I was swapping hosts.  This is my second strike.  I was using EZLok for both so it's not a guaranteed fix.

again the end cap strike is inline with the clips in the baffles

Bummer. I was literally going to do almost the same identical setup with my AKV. I talked with the same Travis from Rugged today after reading this thread last night. He indicated it wasn't a good idea" AKV's are known for having their barrels squared with the gas block vs barrel shoulder". I told him I'd take it as a warning. It's s just strange because I've talked to a few people with trilug setup and it didn't mention any issues. I did find a Alpha Mount from JMAC that looks promising.. However, it has exposed threads which is kindy funky.   https://www.jmac-customs.com/2c-1-2-28-x12-alpha/

I have a similar Jmac muzzle device on my PAP M82 and it has worked very well with my nomad 30. I bet it works well with the AKV.

I know this does nothing for you OP but I was about to buy a 9 and 45 obsidian. But I will now pass and just get an octane 45.

I keep an eye on these threads as I have an Obsidian 9, but I run it in short configuration.  It's come loose enough to affect accuracy but no strikes, knock on wood.

Friend has an obsidian9, it had a end cap strike on a 32acp gun of mine that has known good muzzle threads.  The end cap damage was lined up with the baffle cuts.
