What cans are being used that folks are complaining about?
I have a YHM Wraith that works great with the 15-22. No recoil spring problem. Nothing is barking. Works great on the Sig522 too. That said, the Wraith is a larger sized 1.25in instead of the typical 1in .22 can.... which works out to be a significant volume increase for the same length can (+50% more volume). So maybe the pressure is greater with the little 1in cans that is creating an issue? I've been told that with cans... size matters.
