Very smart move for Vista to get the ammo business, and also for Sierra getting Barnes since they haven't offered a non-lead bullet.
Good move IMO for both Ruger & Marlin. Since Marlin is located in Ilion, NY and Roundhill (see below) will get that Ruger may have to move Marlin production again. If so, hopefully to a 2A friendly location.
Not sure about Franklin Armory getting the dried bones and really just the name of Bushmaster.
Not quite sure how things will play out for JJE. AAC is a worthy asset, Parker is a niche upper-end shotgun maker, H&R has pretty generic products, Stormlake is a solid asset. and DPMS is basically DOA right now.
Roundhill got a pretty good deal for the Remington firearms assets, and the Ilion, NY and TN facilities. We'll see what happens on that end, as per above.
Sportsman's Warehouse with Tapco, but what more to say there.
