Tuning New Huma regulator with a loose screw in the bag?

Maybe it's just me, cause I'm nursing a recent rotator cuff surgery and I'm grumpy. But, if I owned a company, and an employee told a customer that we made a product for them, but we "have not been able" to make instructions for its use, he and I would have a discussion about such an asinine response. I mean really, a 2 sentence explanation is something they are unable to do? Good grief, but maybe I'm wrong, as my wife often suggests.

I'm with you on this one, but my wife also frequently suggests the same as yours.
 
My Huma reg came with that set screw installed in the reg purchased from AoA. It also came with another screw about an inch long to screw into the reg to make removal easier. I attached a piece of heavy string to the screw and can simply grab the string to pull out the reg. This is illustrated in several videos online for Benjamin Marauder rifles. My reg fills quite slowly but does not adversely affect shooting.
