Aero Precision AR-308 M5 Enhanced Carbine Buffer Kit (.308)

The Aero Precision M5 .308 Enhanced Carbine Buffer Kit complements standard .308 rifle builds and includes an Enhanced Carbine Buffer Tube with features designed to improve reliability and simplicity.

AR15/AR10® Enhanced Carbine Buffer Tube Features

• Carrier Support Extensions: Supports and guides the bolt carrier group after firing to prevent carrier tilt and reduce wear. Extensions also secure the buffer retaining pin and help prevent tube backing out under recoil.
• Position Guide Drain Holes: Drain holes in each position guide remove water in marine environments and allow additional air escape for smoother cycling.
• Ramped Tube Design: Enables easy installation of traditional carbine stocks without using screwdrivers to fit the furniture over the tube end.
• Proper Thread Depth: Threads machined to correct depth to reduce risk of stock trapping when fully collapsed.
• Mil-spec Dimensions: Machined from 7075-T6 aluminum to mil-spec dimensions. Compatible with standard carbine stock options made for mil-spec buffer tube dimensions.
