Rugged can came loose

[Pbj ak]

Today I shot 150 or so rounds through my radiant and when I got home I checked to see if the can was still tight before sitting it down. I noticed it was loose and after I took it off, threaded it back on, and tightened the collar I could still turn the entire can with a decent amount of force. I wasn’t trying to heman it off but used what I thought was decent judgment.

Can anyone confirm if this is normal?

After messing with locking collar I noticed it would turn a little farther in the closed direction when off the rifle than when on the rifle. I ended up making a witness mark with a sharpie and when I put the can on the gun I turned the locking collar as far as I could by hand. The marks were ~1/4 of an inch off so I used a set of pliers and turned the collar the rest of the way tight (lined up the witness mark). The suppressor is definitely tighter (on the gun) than it was, but I was able to still loosen the can by hand.

Since then I have taken the can off and reinstalled it as tight as I can get it. Thought I’d shoot it a bit more to see what happens but wanted to see what you guys thought. I’ll also call rugged tomorrow to see what they say.

I hope all that makes sense.

I have zero experience w the rugged rifle mounts but I’ve read about them and used plenty of other mounting systems. If the suppressor can be rotated by hand despite the locking collar appearing snugged, something is definitely not right. perhaps The locking collar is seized and cannot fully tighten. Not sure.

many mounting systems are essentially a taper with no locking collar, such as the griffin or OSS mounts. Those don’t really come loose even without a locking collar. My guess is your locking collar has been dysfunctional since It was assembled and may just not have been noticed. I’ve never had to use rugged CS but they have a stellar reputation. I’m interested to hear what they find.

if I weren’t already invested in several mounting systems I’d be getting a rugged razor for next can purchase.

All I will say is the fewer moving parts the better. No a fan of the QD mounts with all the springs and collars.
Really like the Xeno mount, Area 419 for hunting and cooler applications.
The YHM is Ok also. No moving parts in the mount and the FH is easy to replace or maintain if needed to replace the spring. It also has a threaded/tapered attachment that locks on its own and the spring is extra.

Rugged has some of the best customer service I've encounted. I had a baffle strike so I sent the can back in at Rugged request. They fixed something with it, gave me a new end cap, paid for return shipping and re-coated the whole can for free because they upgraded the newer cans with the same service. They took care of all that for free.

They're sending me a new piston spring after I asked about the spring service life, so can't beat that customer service.

I love Rugged, but my one complaint is that they eat end caps for breakfast. I've had two end cap strikes on my Obsidian 9. The first I can explain (crappy Griffin Armament mount), but the second I cannot. I'll probably just end up buying a .45 end cap to avoid it in the future.

That’s what mine was doing and when I sent it in they fixed that problem. I’d reach out to them and explain what’s happening.

ive not had any strikes with my obsidian 9. For whatever reason I found it very difficult to keep tight with 1/2 x 28 threads. I switched to 13x1LH and havent had it loosen. Perhaps yours unknowingly loosened? Unless the projectiles are unstable it seems a loose mount would be most likely.

in terms of changing the endcap, I’d rather take an endcap strike and know to stop shooting than upsize to a 45 endcap and find out when the baffles take a hit.

the obsidian I’ve found tricky to fully tighten the cap that holds the piston in place. It has an unusual pattern presumably to facilitate hand tightening and not tool use. I acquired the obsidian tool from Hahnson brothers and it was well worth it.

I have a rugged obsidian in jail. It’s my first pistol can other than 22. I’ve considered just doing the Griffen cam lock so I don’t have to worry about the can unthreading itself.

Was this a cam lok or ez lok mount by any chance? If so what are your thoughts on the system, and would you get it again?

I'm looking for a 9mm suppressor as a first pistol can but the Obsidian has so many muzzle strike reports.

The first strike was with the Cam-Lok system. I actually noticed my POI becoming drastically different than my POA and that's when I realized it has loosened. I was probably a few rounds from disaster. I was personally unable to keep the Cam-Lok system tight for even a full magazine. Griffin worked with me and replaced all of my Cam-Lok stuff with EZ-Lok. EZ-Lok is fantastic assuming you aren't constantly moving the suppressor from gun to gun. When it's on there, it's on there, and isn't going anywhere. I think I've had it loosen once in ~4,500 rounds and I check tightness after every mag. Again, the only con is that the suppressor is *really* on there. I've had times that I have to put my barrel lug in a vice to have enough torque to remove the suppressor. That being said, I'd still go with it over Cam-Lok.

The second end cap strike was with the EZ-Lok and, as far as I know, occurred on a day that the can never loosened up. I shoot reloads that are accurate enough for easy 25 yard hits (so no keyholing), so the second strike is still a head scratcher.

Talked to the company this am and dude said to make sure it’s tight on the gun. I mentioned that I could get the can to unscrew after installing it and tightening everything down. He said it was a friction lock and even thought it would release with enough hand pressure it shouldn’t release when shooting. The friction lock is designed so the can won’t seize on the gun. I’m going to assume I didn’t have it tightened enough and roll with it. If I have further issues I’ll post here.

I too have encountered an end cap strike only with my obsidian 45. It was wearing the 45 end cap aswell. We’ll call it my fault. I’m now aware not all mp5 trilugs are created equal lol. I know someone mentioned being cautious of spring/collar mounts, so just a small testimony to that I suppose.

Anyway! Rugged took care of me. They sent me another end cap and I didn’t pay a cent.
