I've seen that video before. Being these parts are tooled by CNC I believe and all I would assume this has happened before. My only concern is failure over time even if I didn't have any initial issues. Especially if the seers don't align properly wouldn't they prematurely wear???? Either way I will be trying mine as soon as my kit ships and from what I am told should be in a week or so.
I thought there was another company out there doing whole Trigger jobs, you have to send them your housing from what I remember as they fit it in place.
