Have a Performance Center 15-22. Installed a Rise Rave 140 custom trigger. Did not work well. Consistently experienced dead trigger fails after initial ignition. Seemed the disconnector was not engaging.

Swapped back to the stock trigger, and no further problems. Long story short, Rise to their credit worked the issue well. Replacing spring rates, and even free upgrading to the Blitz. In all cases the trigger did not work well.

Continued to consistently experience dead triggers and also light strikes/ FTF.

Several types of ammo were used across testing sessions, with the same used for each separate session.

In all cases swapping back to the stock trigger resulted in no further problems. Rise says this issue is unique to them because I am the first customer with a Performance Center.
They have extraordinary success with standard 15-22.

So there must be something about the Performance Center. What that is, I and Rise have no idea. I can only suspect that something is different about the PC bolt, since I think the bolt is the only component with which the trigger interfaces for ignition.

I have not determined if a PC bolt is different from a standard bolt.

Does anyone know?

Does anyone have the Performance Center with a custom trigger?

More generally, anyone have an idea why a PC would not like a custom trigger?
