We broke barriers and won awards when we released the piston driven .308 Revolution. For 2019 we've introduced the Revolution DI (Direct Impingement). By popular demand you get the same technology same durability same features and same AR-15 size but in a smaller direct impingement system featuring our 9-position adjustable Dictator gas block and Renegade rail. There is virtually nothing left to upgrade. - The original Revolution weighed in at a paltry 7.35 pounds turning heads for its incredible light weight and small stature for a .308. The Revolution DI weighs even less at 6.81 pounds with a 16 barrel making it ideal for just about any situation you put it in. - Caliber: 6.5 Creedmoor - Barrel: 20 - Rail Length: 14.5 - Weight: 8.6lbs - Length (Collapsed): 40.5 - Color: BLACK
