The original Alexander Arms Grendel is the rifle that introduced 6.5 Grendel to the world. The 18-inch stainless barrel was chosen to maximize the cartridge's inherently efficient powder burn, and the entire platform was designed from scratch around the new caliber rather than adapted from 5.56. Type: Rifle Action: Semi-Automatic Caliber: 6.5 Grendel Capacity: 26 Year introduced: 2004, USA Weight: 72 oz Overall length: 37" Status: Active Intended use: Long Range, Hunting, Competition
