JG10 .308 Win Complete Upper Assembly – 20″

The Jacob Grey Firearms Low Profile 20” DPMS style AR-10 Fully Assembled Upper receiver is a perfect match for the Jacob Grey 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. The high-polished nickel boron BCG allows for a smoother cyclical action and return to battery, while requiring less lubrication and reducing carbon build up. The matching machined billet aluminum dust cover is a precise fit to the upper receiver. The low profile .750 adjustable gas block allows the Upper Receiver to perform flawlessly and accurately each time.  A .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.
