Suppressors KGM RF22

[IowaPlinker]

A few years ago I bought an R556 from KGM and it came with an RF22.
Due to… reasons, I haven’t had much opportunity to shoot with it until last month.
While sighting in the Ruger mkIII, I noticed that my bullets would keyhole.
I took off the can and fired the pistol and no keyhole.
So I took the can apart and noticed it was much easier to get the front cap off than the rear cap.
Looking at baffles, I noticed strike marks.
I reassembled the can, taking effort to tighten both caps as much as I could.
Upon shooting the keyholes were still happening.
My question is; has anyone had this type of experience with this happening with a KGM RF22 before?
I plan to reach out to them to see if I can send it back for inspect and repair, if they do that.
Thanks for feedback.

I have a couple and haven’t had this issue.

I would initially suspect alignment with barrel threads but hopefully Ruger didn’t get that wrong. A small wood dowel close to bore size from Ace hardware would be a cheap way to check, not as ideal as a legit alignment rod but cheap enough to probably work a time or two if the dowel is straight.

If the baffles are floating an alignment rod won't tell you shit. They will shift back when removed. Call KGM and let them deal with it. It's not rocket science.

Rear cap will carbon foul quicker than the front. Totally normal.

Baffle strikes are an alignment issue. Check the barrel because it is Ruger, and send the can to KGM for a checkup once the cause is determined.

Did he say they were floating?

KGM can't correct for bad muzzle threads. Alignment still needs checked before it goes in.

It wouldn't be the first ruger I've seen that was out of whack. I've fixed a few for several friends of mine.

Its irrelevant. The point is if the can is not locked down or the baffles are undersized in a modular can, an alignment rod is only going to tell you if the hole is big enough, not if its in the right place.

I have a ton of rods from doing can builds years ago. Want to know how you avoid issues? Dont buy cheap guns/barrels made by idiots.

If you buy a quality barrel from a known quantify, these issues never happen. Atleast from a muzzle thread perspective.

It's a Ruger. When you pump out that many there's bound to be a few.

The fact is I'd be looking at the barrel before the can with a pistol that very likely has a warning about not using suppressors in the owners manual.

Well no shit. The other most likely culprit is impropper assembly built user. Hence the post. Both of those are far more likely than kgm making a bad can.

Are/Were not the DA Sierra 5 cans made by KGM?…
