18" 6.5 GRENDEL Stainless Heavy Contour Barrel AR15 Rifle Upper Assembly with 12" Rail and A2 Flash Hider
The 6.5mm Grendel cartridge was first unveiled in May 2003 at the Blackwater Training Facility, where it remained supersonic at 1200 yard range. The goal of the 6.5mm Grendel design was to create an effective STANAG magazine-length cartridge for the AR15 platform that could reach 200–800 yd and surpass the performance of the native 556 NATO cartridge. Firing Factory loaded ammunition with bullets ranging from 90 to 129 grains (5.8 to 8.4 g), its muzzle velocity varies from 2,500 ft/s (760 m/s) with 129- and 130-grain (8.4 g) bullets to 2,900 ft/s (880 m/s) with 90 gr (5.8 g) bullets (similar in velocity to a 77-grain (5.0 g) 5.56 mm round).

6.5 Grendel upperSo far so good. The fit was good with my RRA lower and BCA BCG. It looks like it will be at least a 1 MOA set up, maybe better after some more rounds down the barrel.
