LR-308 Lowers are the heart of the rifle, housing the fire control components, mounting your recoil assembly, stock and buffer. Thanks to modular design the LR-308 platform is a proven and battle-tested design that certainly lives up to durability and standards of its operating nations. Typically Mil-Spec Lower Receivers are typically machined from a forging of 7075-T6 Aluminum. Offering a Lightweight and and incredibly durable/impact resistant weapons grade material. The LR-308 is a derivative of the AR-10 and is not directively compatible with AR-10 Style Upper Receivers. LR-308 lowers incorporate a 'DPMS' style cut in the lower 's buffer tower and upper receiver.

About This Brand: Aero Precision’s roots are deeply tied to aerospace, and their drive for clean, perfect engineering and machining stems from that. When you’re building something that will fly in the air, there is no margin for error. Aero Precision takes that same approach in the firearms industry. Not every manufacturer will have razor thin tolerance levels. Not every manufacturer will personally oversee the development, design, and machining of every part that comes off the line. Aero Precision is not every manufacturer.
