Aero Precision AR-15 Enhanced Carbine Buffer Kit

The Aero Precision® AR-15 Enhanced Carbine Buffer Kit is a must-have for any AR-15 rifle build. Featuring an enhanced 6-position buffer tube, an enhanced carbine buffer and matched spring, and an endplate and lock nut, this easy-to-install kit fully supports and guides the bolt carrier group into the buffer tube to prevent carrier tilt and eliminate any unnecessary wear for smooth and consistent service for years to come. Carrier support extensions extend on either side of the buffer retaining pin to secure the pin in place and prevent the buffer tube from backing out under heavy recoil. Precision-machined drain holes on the buffer tube allow water and dirt to drain from the system in wet environments, while Mil-Spec 7075-T6 aluminum construction ensures long-lasting durability in a lightweight package. Compatible with most Mil-Spec upper receivers. Made in USA.
