Build your ultimate AR15 with a complete piston driven upper from Hardened Arms. Available at an Introductory price of $649.99 for a limited time. Featuring a forward porting gas block with adjustment screw, a single piece carrier and our 10" Talon rail. Enjoy the benefits of an AR15 platform with the reliability and gas system of an AK. The system vents at the gas block rather than gas key of the carrier leaving you with a cleaner running upper. Please note these are available in a very very limited supply as we only received a small shipment from our piston supplier.
