I got a GMR super safety to work 100%.

RTBA / CMMG .22 kit with 16” RTBA barrel
Taylor Tactical reduced power (blue) hammer spring
Bore Buddy weight using aluminum rods

I did replace the GMR lever with a 10% larger “printed” lever to eliminate the slop between the cam and the original lever to correct timing issues.

Runs great with CCI SV and Mini Mags.

Now all of them have the Copperhead Safety/Cornfire in them. This setup seems to run very well in all three. I think it's the design of the lever. Being rounded, it seems to have the most consistent amount of pressure on the trip. The Atrius is very similar in design.

Have to clean then every 400-500 rounds but all of them seem dialed in pretty well.

I have several videos on my YouTube channel, check them out.

In this video, nothing was changed between the unsuppressed and suppressed strings of fire.

Thanks,
 I want a three position and think I may go the atrius rave 140 route.

Might order the trip and rave trigger tomorrow. I also might get the recoil spring kit.

What is the secret in getting the rare breed trigger to work? Trigger kicker is working way better than my Partisan trigger.

With the Rare Breed I used the factory 5lb recoil spring, steel weight housing with all 4 steel weights. Just go slow with small increments when adjusting the trip. It ran best with the old red box Federal (hotter) ammo.

I tried my upper on another lower with an early Partisan in it(the one with the lighter hammer spring). It didn’t work at all. I think if I replaced the hammer spring with the newer, stiffer one it would work better.

One thing I have learned: Try lots of different ammo. One gun may run well with Remington Golden Bullet. The other may run well with Winchester Super X.

I can see where you're coming from, 'cause I know where you've been and I can see where you're going 'cause I can see the direction you're headed in. I just don't know where the hell you're at right now.

Well I dont understand this thing, today three mags and not a single malfunction.

I did use a newer CMMG mag, a mag thats still 12yrs old.

I never thought about using the new partisan hammer spring. I have the old and new one.

Running 100% with CCI mini mags today,update in OP

My No Tune uppers came today.  I sprayed dry lube on it, and put it on an ARC FRT lower.  I fired 4 rounds single, then switched to 3rd and emptied the mag.  I was using CCI Mini Mag.  

I had a CMMG suppressor on it and was ringing steel from about 10 yards.  I didn't bother to put an optic on.  I just wanted to see it it would work.

I walked back to the house with a smile on my face.
I love a good double entendre.

Today I got my arc fire and my BB trip.

Took the trigger kicker lower off and replaced it with the new arc fire lower.

Worked just like yours did, I should have just went with the recommended frt triggers in the first place.

With that said congrats, and to others doing 22 builds, use a arc fire/atrius style FRT.

Bore buddy recommends it for a reason.

Tell me about the CMMG can, I am thinking about getting one.

The CMMG can was one of my early can purchases last year.  I got it because it was about $175 and I know the CMMG name.  I think it is the
predecessor to the Zeroed, but the pictures look like mine, inside and out.  I have only shot it on a rifle with high velocity rounds.  It's like my
KGM R556 suppressors, it's not the quietest, but it works well and didn't break the bank.  I get the sonic crack, but not the boom at the barrel.

I will be picking up a threaded Ruger 22/45 upper next week and I'm hoping it will be quieter.

.22lr is velocity rated in a 16” barrel, so you will have to use subsonic ammo for it to be quieter in a rifle.

.22lr ammo doesn’t reach supersonic speeds in a shorter pistol barrel so you can use standard velocity rounds and it will still be much quieter in the pistol(provided yours isn’t a long barrel pistol).

Thank you.  I'm still learning.

I wish I had gotten the short barrel No Tune upper.  If it was available when I ordered I missed it.
I love a good double entendre.

Well mine shoots win M22 ammo as well.

I have thousands of rounds of that ammo vs mini mags. Mini mags are cheap still but it's nice it will shoot my 22 stash.
