One of the members here was part of the 51t design and explained how they'd made changes to his original design/tooth count which made it less optimal. I forget the exacts. But none the less, if you hold the latch open when mounting the can, you won't dull the latch teeth.
I'd buy a 51t can in a minute if I needed a suppressor and found one priced well.
