Aero Precision Enhanced AR-15, LR-308 Carbine Buffer Tube Aluminum Anodized Olive Drab

Aero Precision took a whole new approach when designing the Enhanced Receiver Extension Buffer Tube by including features like carrier support extensions, position guide drain holes and ramping the design of the tube. These features add reliability, security, and simplicity that traditional mil-spec buffer tube options historically overlook. FeaturesCarrier Support Extensions - Fully supports and guides the bolt carrier group into the buffer tube after a round is fired, preventing carrier tilt and unnecessary wear on key components. The Carrier Support Extensions also extend on either side of the buffer retaining pin, securing the pin in place while simultaneously preventing the buffer tube from backing out under recoil.Position Guide Drain Holes - Each position guide features a drainage hole that removes water from the system in marine environments. During routine operation, smoother cycling is achieved by allowing additional air to escape during the compression cycle of the rifle....
