Bushmaster's Optics Ready Carbine is designed to provide a platform for your imagination: any optics, any purpose, anywhere. The ORC comes with a receiver-length Picatinny optics rail and two 1-1/4" riser optics blocks (perfect for holographic sites, scopes, or red dots) without a lot of extra factory accessories that you're going to replace anyway. But the ORC isn't a bare-bones rifle by any means. Its 16" M4 profile barrel is chrome-lined in both the bore and the chamber with an A2, birdcage-type flash hider to control muzzle flash. A heavy oval M4-type handguard provides a fore-grip while maintaining the ORC's immaculate balance and control. The ORC's six-position telescoping stock reduces overall length by 4" when collapsed for convenient carry. Every ORC is shipped with an operator's safety manual, a detachable box magazine, an orange safety block, and a black web sling. A one year Bushmaster warranty comes standard.
