Common issues with the Super Safety are covered in the Super Safety documentation. You should download the Super Safety release files and read through it before doing anything else. You can find the Super Safety documentation on the design page.

Hello,
I have a brand new CMMG dedicated 22lr upper that I have thrown on my P80 AR lower. I have installed a SS and the “Super Safe” mode is not working. I have a third party trip kit installed, and the semi mode works fine, but the SS mode does not allow the trigger to be pulled (like it’s on safe). I have noticed that if I rotate the SS forward about 5 to 10 degrees, the trigger can be pulled on SS mode. I believe the issue is with the lever not being long enough, or the trip bar being too far back. I have a 300blk upper than I throw on the lower and the SS works fine.
I was wondering if you could provide some guidance as to what to do. I am taking one of my spare levers and adding JB weld to increase the length of the lever on the buffer tube side of the lever. I am hoping this extends its length allowing the trip to push the lever more forward
There are two critical measurements on the trip to get the HTSS running with the CMMG 22lr conversion kit. The first measurement covers how far back the trip pocket travels when the bolt moves towards the rear. If you don’t get enough travel, even though the trigger is resetting, the hammer can release early which will follow the bolt and you’ll get what looks like a light primer strike. The second measurement is how far forward the trip pocket moves as the bolt is closing. This is all about how much cam rotation you get during the cycling of the weapon rather than how far the actual lever moves during the cycling. While these two are related, they are distinctly different. The lever has some play in the cam of the HTSS. If there is too much play, you will not get enough cam rotation. I had to modify the lever with 3d design software and print out a custom lever. In the software, I increased the size of the bulb (the part that slides into the cam) by 12% in both the X and Y axis. I left the z Axis as is because adjusting the z axis would increase the side to side width of the lever. I also started with the shortened lever that is available on many 3d printing sights. You can find it by searching for 22lr super safety lever, or CMMG super safety lever. With a tighter fit between the lever and the cam there is more cam rotation. Once I did this, I then modified the 3D printable trip, through trial and error, to get the most backward cam rotation, and then on forward movement of the bolt, to have the trigger completely freed up for another press just as the bolt closed. I am also using the bore buddy adjustable weight system. I used a casio digital camera capable of 1000 frames per second to see how much bolt bounce I had. I adjusted the weight until I had the least amount of bolt bounce. The entire bolt bounce duration, from initial closing through the bounce and to rest in the fully closed position takes about 4 frames or 4 miliseconds. I also have lighter springs on my hammer and trigger. I polished the sear and notch contact points. My trigger pull is about 5.5lbs as measured in the center of the trigger. I also cut the tail off my hammer. The 22lr has limited power. You have to rely on this power to cycle the bolt, cock the hammer, and reset the trigger. If you have a heavier trigger pull, you are asking the 22lr shell to overcome more pressure from your finger. A lighter trigger pull, proper timing and distance on the trip pocket that moves the lever, a lever with less play (Meaning more cam rotation for the same amount of travel of the trip pocket) all work together to make this cycle reliably in the CMMG kit. I don’t have much use for the bore buddy adjustable trip. It does not have enough forward travel adjustment for my set up, and I can’t imagine that it would for any other milspec FCG. If I didn’t know how to 3d design and print out my own parts, I never would have gotten this system running. I know you posted this question over a year ago but hope that you or others benefit from my findings.
Did you ever figure this out?
Bought SS with trigger already angled with detent cam and lever package. Put it in a brand new Daniel Defense MK 18. Went in pretty easy. Only thing is when you charge the handle. It was gritty and would hang up. Took it right back out and put back original MK trigger. To try and see if it was the rifle. I had never even shot it was new. It functions fine . Going to reinstall it again to see if i can figure it out!
I have two of your super safety systems. I have installed one on my mil spec Colt LE lower. It will not function, and does not let the bolt on BCM 5.56 upper receiver full cycle to the rear to engage a round. I would like to send pictures, but I can’t attach any. I would like some assistance or some direction as to who I can contact for help. These are all high quality components that should work. Thanks for your assistance.
