I ordered some lenses from salj838, and while the cut of the lenses is amazing and it seems like they should work fine.. they definitely don't sit right. Problem is, this isn't the first pair of lenses for the R2 I've gotten. I've got some cheap Revant ones that came with them, and I have linegear as well. All the lenses seem like they should fit perfectly, but they're so loose I wonder if I'm missing something. Is there a gasket or something that holds the lenses in place that I'm missing? I've got the screws in there, but seriously, if I clean the lenses I can pull the lenses out even with the screws in place. Any ideas? I've tried using multiple 100 mph tape shims, but no luck. I'm about to glue the f'n lenses in.
