I saw that one but since I don't have the factory nut and factory muzzle device retainer clip I kind of ignored it. I suppose I could just loctite it to the barrel threads. Quote HistoryQuoted:

This is what you'll need then https://www.hkparts.net/shop/pc/3-Lug-Adapter-For-CZ-Scorpion-Evo-5p17616.htm I have the flash can model so the factory carbine handguard covers my threads but I see your concern if that's not your case. |

I have the same issue, no retaining clip on the flash can pistol/carbine but it doesn't matter. That adapter should butt up against the handguard nut if you're using the factory handguard. For me, I plan on using rocksett anyway to keep it secure and can easily be removed albeit with the 3 lug adapter tool. |

I can't help you with the Griffin 3 Lug issue but my In Lead We Trust 3 Lug muzzle adapter fits perfect in my Obsidian 3 Lug mount, so I'd say it's the Griffin. Just so you know, that was one of the 3 Lug mount brands that Rugged advised me NOT to use. Both TROS and ILWT are GTG muzzle devices for sure with the Obsidian. I contacted HK Parts and asked them what the deal is. They said that Griffin does not build their 3 lug adapter but there can be variation in the part and they offered to send me a replacement after getting mine back. I asked them if they could instead send me the Scorpion 18x1 3-lug instead and they said yes. They did say they've had reports of Obsidian suppressors not working with their 3-lug adapters on occasion so I guess we'll see when the new unit arrives in a week or two. |

I received the Scorpion 18x1 3 lug from HK parts today, it also does not work with my Obsidian.

Our 3 Lug Mount is designed with tight tolerances and we've found from time to time some 3 lugs have issues with it. If you can send an email to [email protected] we'll make sure you're fully taken care of.

I can confirm that the In Lead We Trust 3 lug adapter, which is supposedly built to the same specs as the standard HK adapter, does indeed work well with my Obsidian 3 lug mount. I have it on my Scorpion Evo and it's got a nice solid lockup.
Also, for the guys running an aftermarket handguard that now have exposed 18x1 threads, I also had the issue and found the below solution. Not perfect, but it definitely looks a lot better than just leaving the barrel/threads exposed. Evolution Gun Works 18x1 thread protector in the link below. http://www.egwguns.com/ar-rifle-parts/thread-protector-carbon-steel-18x1mm-for-tikka-varmint/ Pic from another owner on the Scorpion Evo FB group.

I have an obsidian, and I've had the endcap and 3 lug back off a little. I haven't had any issues with it because I've caught it in time. I'm curious if anyone uses loctite to keep these in place, or should I just apply more torque?

I planned on using rocksett when I eventually get a tri lug mount. Maybe overkill on a pistol caliber or it maybe not. Blue lock tight maybe good or it may not hold up to the temp. Why not just go w rocksett? Quote HistoryQuoted:

I'm mostly curious what other people have done. I haven't put any thread locker on yet because I'm thinking that I might want to make it easier to change to a different attachment method later on. I realize that without a locker on there it coming lose will always be a possibility, but if others aren't running into issues after only using torque and no thread locker, I'd just torque mine a little more. If the problem can only be solved with rockset or locktite, then so be it. Loctite makes a high temp version of blue, 242. It does not have the higher torque rating of Rocksett but should be okay for a pistol caliber weapon. |
