I just checked out the video in the site posted above and the SureCycle IS non-locking and rotating. I don’t think it’s a big issue but I’d prefer the locking style.
It’s kind of like when I purchased a bolt handle for my old Benelli M1. The factory handle didn’t lock in place, but it also didn’t rotate. Some aftermarket makers made rotating handles and others made non-rotation handles. I went with a non-rotation for the M1
