The Jacob Grey Firearms Low Profile DPMS style AR-10 Warthog Fully Assembled Upper receiver is a perfect match for the Jacob Grey Warthog Billet lower receiver. Not only have we designed an upper receiver that is aggressive in styling, but also weighs less than standard AR-10 Upper Receivers. Excess material was removed from every spot possible without sacrificing the structural integrity of the receiver. Whats left is one of the most stylish, well balanced upper receivers on the market today. The matching machined billet aluminum dust cover is a precise fit to the upper receiver. The low profile .750 adjustable gas block allows the 'Warthog' Upper Receiver to perform flawlessly and accurately each time. With the assembled upper receiver weighing in at just 5lbs complete (bcg, ambi-charging handle and billet dust cover included), with the addition of a 12.5 1/10 twist .308 CMV Barrel, Jacob Grey Firearms has finally done what has been asked for years from AR-10 manufacturers. A pistol length .308 caliber AR-10 upper receiver with the agility and weight reduction to add to your AR-10 lower receiver without compromising any of the features and performance expected from your firearm.![]()
