New for 2020 is our BKF M4 MOD-0 Forged Lower Receiver that is part of our new Duty Grade Series. It is available as a builders set, receiver set, lower or as completed weapon system. The Duty Grade Series will offer a vast number of BKF components that have been made with the AR builder in mind. Not only does the Duty Grade Series offer extremely high quality USA products, but it also offers very competitive pricing. This is not any old AR15 forged lower.
