After the Sandy Hook shootings the big conglomirate as you call them (Freedom Group which is owned (94%) by Cerberus Capital Management) has chosen to sell off their holdings.
Not sure if any of it has happened yet and if it has, who has bought them up.
They own Remington, Marlin, H&R, Bushmaster, Dyncorp, DPMS/Panther Arms, Dakota Arms, TC, S&K, Advanced Armament Corporation, Barnes Bullets, The Parker Gun Co., Mountain Khakis, Para™ USA, TAPCO, IAP Worldwide Services along with possible others.
The Freedom Group does not own the Smith & Wesson Holding Corporation or Strum Ruger, nor does it own Colt, Winchester or Browning.
