6.5 Grendel

Following months of design engineering and testing, CORE Rifle Systems is pleased and extremely excited to introduce a new rifle platform, barrels, and accessories to the CORE Rifle Systems line up for 2016. The 6.5 Grendel.

The 6.5 Grendel rifle is now available in two CORE platforms, the new TAC 6.5, and all the HARDCORE models. As part of this the 6.5 Grendel is also offered in both 18” and 20” CORE Rifle System barrel lengths.

The 6.5mm Grendel design goal was to create an effective 200-800 yard AR-15 magazine length loaded cartridge for the AR-15 platform that surpassed the performance of the native 5.56 NATO/.223 Remington cartridge. Constrained by the length of the 5.56 mm NATO round, the Grendel designers decided to use a shorter, larger diameter case for higher powder volume while allowing space for long, streamlined, high ballistic coefficient (BC) bullets. Firing factory loaded ammunition loaded with bullets ranging from 90 to 129 grains (5.8-8.4 g), its muzzle velocity ranges 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 5.56 mm 77-grain (5.0 g) round).

The case head diameter of the Grendel is the same as that of the parent case the .220 Russian, the 7.62×39mm, and PPC cases. This is larger than the 5.56×45mm NATO, thereby necessitating the use of a non-standard AR-15 bolt.

The 6.5 Grendel has proven to be highly effective as both a competition shooting round and a hunting round. Because of it’s flat trajectory the round has been successful in hunting  small to large game including Bear and Elk.
