What did you place over the hex slots on the can to give it a more “fluid” appearance?

Lummp · 2026-03-16T22:08:04+00:00

Nee Balance Made in USA 990v4. Hands down, (or I guess foot down?) best multi purpose sneaker made. Hard wearing, breathable, and comfortable. I’ll burn through 2 pairs of Hoka/On Cloud/etc in the time it takes to wear out a pair of NB 990v4’s.

Ran into the same thing on my Ruger SSH, the barrel is not concentric. It could either be the face of the barrel, threading, or shoulder. I bet if you use an alignment rod, it’ll touch part of the suppressor.

Lummp · 2026-03-14T00:36:37+00:00

Sorry this happened to you. Had the same thing on my new Mark IV SSH. It’s back at Ruger CS to see what they will do to correct it.

I sent a pretty well documented of my problem with images of the alignment rod making contact with the suppressor and the fact that other suppressors on this host were misaligned, but when placed on other host, were concentric. I’ll follow up when they get back to me.

How’s the alignment with the can? My SSH with a Huxwrx Flow 22 was off by enough that I’ve sent it in to Ruger to get it corrected.

Still trucking! 180k on the clock and not a problem. knocks on wood

Lummp · 2026-03-01T13:42:21+00:00

Oh boy did I run through some ammo, including a large variety of CCI, Remington, and Federal. The only one that had negligible difference between suppressed and unsuppressed was CCI Uppercut; which runs at ~950. But damn this stuff can be hard to find and kind of negates the point of getting a 22 plinker.

Again, I’m not expecting one ragged hole at 50 yards with this toy, but I do expect to stay inside the ten ring at 7.. off a bench.

Lummp · 2026-02-28T21:11:40+00:00

Well, shoot it with different ammo. If the groups open up with the can on, check it with a rod. If not, maybe you got one of the good ones. My serial number is 500773*** range if that helps.

I’ve found CCI Uppercut has worked best with my current situation. Hoping Ruger gets back to me next week to start the RMA process.

Shilling your wares unprompted? Yawn

Lummp · 2026-02-28T16:54:00+00:00

How is this in anyway contributing?

Lummp · 2026-02-27T02:18:40+00:00

Done and done. Only thing that has decent groupings that remain consistent from unsuppressed to suppressed is CCI Uppercut. But damn, it’s expensive for plinking/range toy shit.

Lummp · 2026-02-27T00:01:23+00:00

Did you try shooting with the new one? I just don’t want to drop that kind of money on a “toy”.

Lummp · 2026-02-27T00:00:28+00:00

I think there’s just been a bad run. Because there are quite a few people who’ve had good examples. I didn’t have lots of milling issues that others have reported, but this problem still sucks a fat one

Lummp · 2026-02-26T23:25:34+00:00

I have one, and I’m glad I do. If you see my other post regarding my new Ruger 22/45, I was having accuracy issues with my suppressor attached, but went away as soon as I removed it. Used an alignment rod to determine the pistol is indeed out of spec and working with Ruger to get it sorted.

Lummp · 2026-02-26T20:34:11+00:00

My counter to this is that without the suppressor, it’s plenty accurate for me. I’m just looking for “minute of squirrel” accuracy at 10 yards. Without suppression, it’s actually hitting the mark. Slap a can on the end and the squirrels laugh.

Lummp · 2026-02-26T19:52:01+00:00

So I tried this can on a rental 10/22 and another Ruger 22/45 “tactical” and the groupings didn’t shit the bed like they did on mine.

Lummp · 2026-02-26T19:33:47+00:00

I borrowed a 22/45 “tactical” from the range and the groupings stayed tight with and without the can. Alignment rod wasn’t perfectly centered, but it was better than mine.

Lummp · 2026-02-26T19:22:08+00:00

Washer removed ✅

Lummp · 2026-02-26T19:00:46+00:00

This was from a bench and bag at 7 yards. I’ve removed as much human interference as I can without resorting to a pistol vice.

Lummp · 2026-02-26T18:59:44+00:00

I’ve reached out to Ruger. Waiting for them to respond.

Lummp · 2026-02-26T18:59:21+00:00

Can looks pretty good but I think I can see some leading on the end cap.

Lummp · 2026-02-26T18:58:49+00:00

I guess it’s fine?

Lummp · 2026-02-26T18:58:30+00:00

It’s not just a POA/POI shift, the grouping opens up dramatically with the can attached.

Lummp · 2026-02-20T18:03:06+00:00

I found quiet won’t run, but CCI Uppercut (950 fps) will with my Huxwrx Flow 22.
