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).

Excellent workmanshipRight out of the box I noticed the quality of the upper. Will buy again.David Rasmussen
First purchaseReceived 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 businessElmer
Fits like a glovePackage 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.KK
Good UpperOnly shot 20 rounds but put 4 into 1.5" group functioned perfect.Jeremy Stagg
