2/3/21 - This is a mint, as-new-in-box example of a rare Armalite AR-10B Rifle, chambered in 7.62x51mm NATO. In 1995, former Army Ordnance officer Mark Westrom, owner of Eagle Arms, purchased the ArmaLite brand and the company became ArmaLite Inc. Shortly thereafter, ArmaLite Inc. introduced the completely new semi-automatic-only AR-10B rifle series. Notably, the AR-10B was not designed using the original AR-10 drawings from either ArmaLite or Artillerie Inrichtingen, but instead was based on the AR-15A2, with parts scaled up or redesigned as needed to fire the 7.62×51mm NATO cartridge. The AR-10B prototype was composed of individual sub-components tested on a special lower receiver made of two slabs of aluminum fitted to a Knight's Armament Company SR-25 upper receiver assembly, and prototyped using computer analysis. The full prototype AR-10B was the first rifle off the production line. This one comes with the original box (serialized to the gun), packaging, owners manual, four 30-rd magazines, and two 15-rd magazines. The gun is mint, and the bore is mint.
