20" 6.5 GRENDEL Stainless Heavy Barrel AR15 Upper Assembly with 15" 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 upper.Received the 6.5 upper I ordered in good condition, with ample amount of packing to protect it. For the money I paid, it was an awesome deal. Only downfall to it is that it took a little longer than expected to receive it. Ordered parts from other distributors to finish the build on the same day, and was waiting for the upper. No big deal though. Good quality at a fair price. Definitely recommend ordering from ar15part. Im definitely going to. Thanks Ar15part! Another happy customer.P. Randall
AccurateShopped hard for these and this seemed to be the best deal for my money when comparing features vs. value. Very accurate and very pleased with my decision.Bart G.
All goodEverything fit just as it should on my lower and seems very well constructed. No hick ups or FTF's at the range yesterday. Very happy and what a great deal.
