XO Carbon .260 Remington

If you’re considering a .308 patterned AR platform in calibers other than the tried and true .308, then look no further. The Executive Order (XO) in 20-inch trim is a lightweight, accurate, hard hitting carbine. Available only with a 20-inch Proof Research barrel, you can choose between .308, .260 Remington, and 6.5 Creedmoor chambering to fit your shooting needs. The longer barrel ensures that you can extract maximum velocity from your projectiles. Ambidextrous controls make operating the XO a cinch for any shooter.
