I agree with literally everything in your post but one thing: the state of Magpul today. Magpul developed and released the Gen 1 pmag the same year as the Masada (2007). Since pmags feel ubiquitous, like IPhones, they feel like they’ve always been here. Between their massive foreign and domestic military magazines contracts, they are a much more substantial company. 2020 Magpul is a $50 million a year in revenue company that can absolutely afford to put together the ACR the way it should be. Even if they contract out the receivers, barrels, and bcg’s to Remington. I think Magpul has a golden opportunity to profit from the mismanagement of Bushmaster and steer the ACR-ship right.
