The 6.5mm Grendel bridges the gap between the 5.56 NATO and 7.62 NATO rounds, delivering greater terminal energy at range than either cartridge. If you want to start an AR-15 build chambered in this unique cartridge, here's what you need.
This is a Complete Upper Receiver, quality-made in the USA, with forged 7075-T5 upper, forward assist, and dust cover. The 16" M4-profile barrel comes capped with a Knight Stalker flash hider. It comes complete with a 6.5mm Grendel-sized Bolt Carrier Group and Charging Handle.
