I do somewhat recall some things with Brownells and the ARs, but at that point I was getting tired of the behind the scenes infighting.

I just assumed they decided to split with each other professionally before they started to dislike each other personally.

Ian not wanting to bite the hand that feeds is understandable to a degree, but him walking that path only helps him and the toxic parts of the fanbase.

Oh I dont recall fully, so don't take what I'm about to say as facts..

But I believe the "official" reason was that InRange was taking up time Ian needed to travel to do episodes for Forgotten Weapons.

and I believe the unofficial reason was something to do with the company that originally made and sold the What Would Stoner Do AR for them, And how they ended up outing themselves as assholes for using like..right wing dog whistles and antiLGBT things for discount codes, Which Karl has zero issue calling out on, but Ian was more interested in avoiding making a public stance on any of it and risking being political, and causing any harm to his relationship with that company. So Ian parted ways and, if I recall, has had zero interaction with InRange since.

Again, I reiterate, its been a while since i last brushed up on it, and I may have details wrong, so do not take this as hard and true fact.
