So I got a WE M4 Charging handle as in the link below as I hear the original one will break at some point.

It is beyond tight to install. The original handle slips in and out of the upper with no fuss and slides smoothly; the DYTAC one has to pushed up into the receiver when you line up the ears and you can only push it forward a few mm before it's wedged.
The package itself is labled WE M4 GBB. Has anyone else put one in? Any feedback? I don't want to hammer it in, and I don't want to grind it either. I have a film of grease in action so it's not a dry metal on metal situation.
