20" 6.5 GRENDEL Stainless Heavy Contour Barrel AR15 Rifle 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).

    20” 6.5 Grendel Upper

    Everything about it looks good and solid. I can’t wait to find a range long enough to see how accurate I can get with it.

    First purchase

    Received my 6.5 Grendel upper and 10 round magazine in two days. Everything was packaged nicely and 100% satisfied with the price and a product. They will definitely receive my future business

    Fits like a glove

    Package arrived within the week I ordered. The only reason I'm not giving a full five stars, cause I noticed a few scratches along the handguard and the bcg was bone dry. Other than that it works like a dream. Took it to the range and ran around 100 rounds with no hickup.
