Aero Precision 308 Carbine Buffer

The Aero Precision M5 .308 Carbine Buffer is a specialized action buffer designed for short-stroke .308 carbines with collapsible buttstock assemblies. This buffer is essential for ensuring reliable cycling and predictable recoil impulse in compact firearm configurations.

Weighing 4 oz, this buffer is optimized for the unique spring-mass relationship required for proper bolt carrier group dwell time and extraction reliability. It is specifically engineered to accommodate the reduced receiver extension travel and lighter spring rates found in carbine-length platforms.

The M5 platform designation ensures compatibility with .308 carbine upper and lower receiver sets, making it a vital component for operators, precision rifle builders, and law enforcement agencies. Proper buffer selection is critical for maintaining extraction reliability and overall firearm performance in mission-critical situations.
