The LAR-9 Carbine brings the 9mm pistol-caliber AR format to a 16-inch rifle-length barrel configuration. The blowback system is tuned for reliable cycling with the wide range of 9mm ammunition available at rifle volumes, and the 16-inch barrel extracts maximum velocity from the cartridge. It competes directly with the Colt 9mm Carbine at a lower price with Rock River's fit and finish. Type: Carbine/Rifle Action: Semi-Automatic Caliber: 9mm Capacity: 33 Year introduced: 2006, USA Weight: 32.5 oz Overall length: 32.5" Status: Active Intended use: Competition, Home Defense, Training
