another issue with my jm pro. looks like i ran into another common issue with my jmpro
I had to sand my pusher assembly down to get it sliding smooth over the barrel
I'm forseeing that to be a weak spot later on
I did not find any excessive wear or galling on Pin.
I think Mossberg, just miscalculated Pin diameter.
As you can see in the attached picture, they went from large diameter to smaller and smaller.
That looks ridiculously short for the job it does.
When I made my own pusher assy, I made the pins have over an inch of engagement into the pusher body.
I'm sure Mossberg will replace it. But, dang.
